"Charlie is a consummate professional - not only is he an exceptionally knowledgeable ColdFusion consultant, but he's also an outstanding educator and mentor. My team and I have been developing ColdFusion applications for decades now, and Charlie is our go-to resource for any circumstance in which we feel out of our depth. His rates are exceptionally reasonable: by way of illustration, a single half-hour session with Charlie saved our team from dozens of hours of code refactoring. He's incredibly prompt to reply to our requests, his answers are thorough and insightful, and his technical skills are unsurpassed. In addition, he never fails to follow up to ensure that his consultations fully addressed our needs. We trust Charlie with our most valuable CF projects, and I can't recommend him highly enough!" (from LinkedIn) (2019)
Michael Fleischmann
Co-Founder at Permia
"Charlie Arehart has been a tremendous asset to our business. He has prodigious knowledge in so many areas related to IT. I got to know him through his CF server troubleshooting business and I have been delighted with his stellar service, vast knowledge, availability and professional approach to teaching and problem solving. It has been a pleasure working with him and I highly recommend him for server troubleshooting. He is also very experienced with SQL server database and other technology platforms. If you are stuck and are looking for a top-notch IT professional to remotely augment your staff, give Charlie a call. You will not regret it" (from LinkedIn) (2019)
Dr. Ajit Thomas
CTO at MaxBounty
"Having worked with you more than once now, I've been extremely impressed with your quick response time, problem-solving ability, professionalism, and interest in not just fixing the problem yourself but also building up our own troubleshooting skills. Your methodical, step by step investigation transformed a confusing, hair-pulling server issue into a clear problem with a simple solution, which in this case turned out to be a low level cloud infrastructure issue that had nothing to do with CF or our app code. You are a web app troubleshooting rock star, and anybody with significant CF deployments ought to keep your contact info handy." (2019)
Conan Saunders
"Thanks to you, the problematic server is much more stable, and we're continuing to squash bugs with the assistance of FusionReactor." (2019)
Kyle Shiflett
Mental Wildfire
"Thanks for your help. I've been used to figuring things out on my own, and with the assistance and guidance you provided, it actually led me to new things to look at which I was able to build upon. In fact, your help was so above par in giving me insights and tool recommendations that I've not needed to reach out again for technical assistance for a long time. But rest assured that if that need does arise in the future, I would not hesitate to reach out to you first." (2019)
Brian Cain
Development Team Manager, CareersInFood
"I have enjoyed immensely working with you on the CF issues. Your energy and devotion to help a person learn and resolve issues makes you a 'one of a kind' person. One I will ALWAYS appreciate and respect. I want to thank you for the time and patience you have always showed to me." (2019)

Nick Powell, Director of IT
American Association of Individual Investors (AAII)


"We really get value out of our sessions with Charlie. I refer to him as the 'CF counselor', like a marriage therapist—but for dev/ops teams. He gets us all to take a close look at issues and review them, then we generally reach breakthrough's with his direction. Of course, and to mix metaphors: sometimes I do wish he could just "paint the house and mow the lawn for us", rather than leading us in how to "do the work" for ourselves, but we know that what doesn't kill us makes us stronger. :-)" (2018)
Jason Solarek
Bridge Store & Network
"We really appreciate your recommendations. One of them I honestly don't think would have ever crossed my mind, but was the first step that got us going. The troubleshooting help you provided was extremely valuable as it got us looking at the right spots in FusionReactor which enabled us to uncover errors and possible sources of our CPU spikes. Thanks so much. As always, we'll be ringing your number when we are in our next crisis! We appreciate having you in our corner when trouble hits. Our conversations always prompt us with lots of new possibilities to research!" (2018)
Dan Rutledge, CEO/CTO
"All I can say is wow. I'm feeling so good after you solved the biggest tech problem we have had for years, that I just went out and signed up for a an expensive class I've been wanting to take. We probably spent 35+ man hours on our own trying to solve a problem which you solved in less than an hour. With 10M visitors hitting it a year, a tech problem affects many people around the world. So I'm breathing a big sigh of relief now. Should have called you sooner." (2018)
Mike Robinson
"I personally really appreciate you. You've shared a tremendous wealth of knowledge out there with the ColdFusion community and so many of us have benefited from your time, efforts and sharing. Hope our paths cross again in the future!" (2018)
Holly Swartz
"Everything has been going smoothly, memory usage hovers at about 10% even with heavy loads, cpu is solid as well. Thanks again for your help, and if there is anything else we need assistance with I will definitely contact you." (2018)
"You're like Batman, Superman, and the other superheros! It was a total delight 'meeting' you (online) and experiencing your expertise in ColdFusion. We could tell in just a few minutes that you and your knowledge are exactly what we've been needing to help us figure out why we were crashing a dozen times per day. You're awesome—and we're sold on FusionReactor also. Thank you sooooooo much." (2018)

  • Garrett Diehl, System Administrator

  • Lee Farrell
    "Everything is running great since we meet. Sessions came down to about 45k from 1.5 million over a few days since we made the code change. Heap is flat maintaining about 2gb and never trending upward like it did before. I think that's the fix we needed, about that and some related issues. Site performance is great and this is the first time in a long time we've gone so long without a reboot.

    I'm now reconsidering some environmental upgrades we were considering, now that things are running fine where we are. Your assistance was invaluable: you helped us find in one two-hour the solution we'd been seeking for over a year on our own, so your time was money well-spent."

On day one, the CF site had to offer its own SF login and handoff to two 3rd party sites. Those integrations worked seamlessly and perfectly! And that, my friend, is in large part due to your heroic efforts with me over a holiday weekend. Charlie, I can't overstate how important and valuable your time and work with me was. My success with this SF integration – and all the moving parts – could not have occurred without your few hours of guidance and help. Thank you, and should I have a need for help in the upcoming months, I won't hesitate to ask for your help again. BTW, a big thank you for your CF posts and pearls of wisdom I have read across the web. Priceless, honestly!" (2016)

In the end, you not only are up and running, you also know why." (2016)

Initially, we had little hope that much could be done after trying every single solution that was suggested online. I was amazed later to see how much deeper you were able to go in your trouble-shooting and eventually finding the cause of the problem and resolving it. I'm not only relieved that you fixed the ColdFusion outage problem, but your fine-tuning and optimizing of CF and IIS has made our websites noticeably faster and lighter. The CF uptime has been 100% since we last spoke! No problems there whatsoever. I couldn't be happier!" (2015)

    "Charlie's the uber-santa. Let me explain: there's a movie called, "I Am Santa Claus". It's a bizarre documentary from 2014 about five guys who are professional Santas, ie; they get hired to be at a department store or mall or to go to people's houses. Some are better than others. Some are higher priced than others. Some have been doing it longer than others, etc.

    But for all of them, whether they're members of the Fraternal Brotherhood of Santa's or whatever the union is called, there's this ONE GUY who they all recognize as the real deal. The uber-Santa. The Guru Santa to whom they all eventually will make a pilgrimage to learn how to be the best Santa they can be.

    That's Charlie. :-) Well, you get my drift. Charlie gets sh*t done."

    "I've been using CF since 1995 and love it. We brought Charlie in to help with some ColdFusion performance woes we've experienced lately. It turns out the recent problems had nothing to do with ColdFusion inherently, or code (as I suspected), but rather was an issue with some configuration settings. Charlie helped us find, understand, and change what was needed, and since then we have had no unexpected restarts!

    He should have meta tags that reflect 'Mental Health Professional' as prominent as 'ColdFusion Performance Guru'. As an entrepreneur, who's spent my whole life creating value out nothing, Charlie's the greatest value-proposition I've ever had the luxury of working with."

  • 2011

  • Ken Smith, Director, Technology Solutions
    We contacted Charlie because our server was performing poorly. In helping us analyze diagnostics and logs, he demonstrated pretty quickly that the problem was not in fact CF, but Apache. That helped take the pressure off our consideration of our app or the server (or CF) being the problem. While we investigated Apache, Charlie suggested we might consider IIS instead, noting that IIS 7 was quite an improvement. Though we had some Apache experts identify some needed changes (for our Windows 2008 R2 setup), we ultimately tried and like IIS 7, and our site is screaming. So, thanks, Charlie, for everything: keeping us from second guessing our application, and turning us on to IIS 7, so we have the super fast site we'd been missing. (2011)
  • Garrett Christian
    CTO, Terra Dotta, LLC
    When we first approached Charlie with a critical issue affecting our production systems, I certainly expected good results, based on his reputation and extensive writings and contributions to the ColdFusion user community. Indeed he did get us through the vexing issues (due ultimately to configuration settings) and got us on our feet again, but what came as a surprise was the wealth of knowledge that Charlie provided in wide ranging areas of system management and troubleshooting. He pointed us to tools and techniques, shortcuts, and undocumented nuggets of information that we continue to find useful and which have made our engineering and support teams stronger and more able to tackle adverse events.

    It's Charlie's patient, methodical attention not just to problems, but his attention to the education needs of his clients, that makes his consultation service unique. He's a gifted communicator and teacher. He starts without preconceptions or assumptions and builds his investigation by observing key diagnostics, all the while carefully questioning and listening, picking out details that reveal the need to give the client more insight to have a foundational understanding of the areas involved.

    Charlie's always reasonable, forthright, and honest with his billings. We're glad to have him as a resource when needed, and we will certainly continue to rely on him going forward.
  • Nicolas Glinoer
    Walking men, a digital agency
    Our server is doing much better - and your help getting us started with FusionReactor was extremely invaluable - thanks again! While we didn't find any one silver bullet that was bringing the server to its knees, in the process of looking into things based on what we learned during our brief session with you, we ended up optimizing a lot of things afterward (code, configuration, caching, etc.). Being able more readily see the impact of spiders on things was also really helpful.

    Our situation is significantly better now. We could not have done it without the insight you gave us into the treasure trove of data provided by FusionReactor. We won't hesitate to get in touch again for our future CF-server needs - it was a pleasure to collaborate with you.

His training skills are very strong: He not only explains and teaches well, he challenges one to think. He handled our heterogenous group with amazing grace (and patience). The entire office was delighted with Charlie's efforts.

    I have worked with several world class consultants in this arena, and while all were exceptional, I give Charlie my highest recommendation. I intend to use his services again when I have need.

    We were having some trouble with one of our applications eating up memory so I searched Google for 'coldfusion consultant'. I clicked on Charlie's website www.carehart.org and instantly recognized his picture from a number of postings that I had read on Adobe's DevNet page. (Here is an example.)

    I sent him an e-mail with a general description of the issue I was having, he responded very promptly.

    Working with Charlie has been a joy. He helped me quickly identify loose ends in the server configuration as well as areas in code. The best thing about the experience is that rather than just peek at code and server configurations and then make changes, Charlie walked through both with me over the phone and online. The whole process became a learning experience with my own personal instructor looking over my shoulder.

    I feel smart for having chosen Charlie as go-to resource.

  • 2007

  • Karin Stevenson, PowerWeb Development Manager
    CyberWolf, Inc.
    We started working with Charlie Arehart in February of 2007 when looking for help with some of ColdFusion's more challenging aspects which had suddenly started to affect our operational stability.

    Charlie was extraordinarily helpful, not only by working side by side with our IT staff, analyzing even the (to us) most obscure bits and pieces of the ColdFusion setup and configuration on the servers, as needed, but also by pointing us to many tools that have proven invaluable to us since then (from general load testing tools to log analyzers and ColdFusion monitoring).

    Thanks to Charlie we were able to understand and remedy issues on multiple levels within short time. His great ability to teach while solving problems makes him an extremely valuable partner to have.

    Even today, with a lot more experience under my belt, I consider Charlie my "CF Guardian Angel" and never hesitate to consult him when I have a problem. And I never walk away from a discussion with Charlie without having learned something valuable.
  • Barbara S. ONeal, President/Co-Founder

    I was very pleased and impressed by Charlie's professionalism and knowledge, not only with FusionReactor and ColdFusion but with other simple shortcuts as well.

    I've worked with Charlie for about six years, but have known of his excellent reputation in the ColdFusion world for about ten. I work for a large Fortune 100 company. My group is responsible for the company's internal web site, which has over 35,000 users and gets close to 2,000,000 hits/day.

    Charlie has been a very valuable resource for my group. Working with Charlie is an absolute pleasure. His outstanding communication skills enable him to teach people unfamiliar with the software, as well as explaining technical details to experts in the field.

    Charlie has helped with examining and quantifying performance for ColdFusion. He explained the different components and how to measure, examine and understand the feedback from these components.

  • "Folks, this is the holy grail of "does anybody know of a tool that can do...." if it exists, it's on this list. not only was i suprised by how all-encompassing this list was, but it's also remarkably up-to-date. it's one thing to put forth the effort to compile such a list. it's another to put forth the effort that it must take to maintain it and keep it useful. Twice in the past two weeks i've been duly impressed by two of the many resources that charlie manages. i figure that if nothing else, that deserves a public "thank you" at the very least. so, thanks charlie. i'm sure i speak for quite a few people when i say that all of your efforts on behalf of the community are appreciated.",
    Charlie Griefer in a blog entry discussing Charlie's CF Tools/Resources to Consider list.

He's a tremendous asset to the community, has produced countless excellent presentations and articles and columns and he works very hard to provide much needed, approachable information for people new to ColdFusion.",
    Sean Corfield, in comments on a blog entry
  • "Thanks...to one of the true leaders of our community. I can still remember reading some of his first articles in cfdj, and I was really impressed, because to me, I wanted to learn more, do more, and be as efficient as possible. To me, he seemed [to ask], "how can I help people from any level of experience in cfml, program faster, easier and more efficiently?" From his tips about CF Studio and Homesite, to his different articles on developing. I mean we all knew synax of Cf, but putting it together in a professional and efficient manner isn't something that we had the ability to take classes on. So in bits and pieces, he is the guy that gave you that extra depth, made things faster for you to develop. Gave you some undocumented features and knowledge of how CFML works. I think that it is because of cf writers and programmers like Charlie Arehart [that] I wanted to blog and become a writer. Remember your committment to the cf community: is not just about how many articles or books; it's about your passionate committment to the craft of programming in cfml. Thank you Charlie",

    Allen Underwood, Consultant, UPS (endorsement as offered on LinkedIn)
  • "I worked with Charlie for over 3 years and found him to be one of the nicest, smartest and most patient people I have ever met. His knowledge of CFML is second to none and his overall IT knowledge is amazing and ever expanding. Finally, he is a wonderful teacher!",
