    "Thank you for your help on Wednesday. You really saved us. It is always awesome to work with you. The ColdFusion server is running much better and we haven’t had any issues since." (2017)
  • Mike Chytracek

    "After a few hours with Charlie taking us on a pretty deep dive into both the JVM and our application logs and making a few recommendations, our CF11 server is running better and more efficiently than it ever has." (2017)

    "All the changes you made worked amazing, no issues since then...performance has been great." (2016)
  • John Kennedy, Sr. Dir of IT
    NASPA
    "I just wanted to thank you and tell you how well our SalesForce integration went. It’s been a huge success. With your help and tutelage, the oath SF process worked like a charm! 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)
  • Michael Duebner
    "The service and expertise we receive from Charlie is first rate. Charlie's approach to solving a problem is unique in that he doesn't just wave a magic wand, although you may choose this option, instead he explains in appropriate detail the changes that need to be made and what the impact will be. In the end, you not only are up and running, you also know why." (2016)

  • Alex Saberi
    Episcript Solutions
    "I want to thank you again for resolving the stubborn problems that we had with ColdFusion for quite some time. 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)

    [Referring to Charlie's blog posts and forum contributions] I just wanted to say that the thoroughness of your replies (present and past) on troubleshooting subjects are not wasted effort. Your efforts to encompass and discuss a wider view of the issues at hand in order to better understand a topic are always appreciated. As a usual lurker on various resources where you write, I don't always say thanks when something helps me out and I wanted to tell you. (2014)

    "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."

    The time we spent together was valuable. I refactored a troublesome scheduled task and the server has been running for 34 days straight now. (2012)

    "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."

    "Once again @carehart proves to be my special Devops super hero. If you need server troubleshooting help, he is your man! #ColdFusion #IIS" (written via twitter, reposted and attributed here with his permission) (2012)
  • Bryan Evans

    Thanks for your time. Our folks are very impressed with your knowledge and how great you've been to work with. You'll always be the first person we call if we ever run into a problem. (2012)
  • Ken Smith, Director, Technology Solutions
    AssettNation.com
    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)

    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.

    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.

    You were a big help to us and still are. Our ColdFusion programmers are always using your website as a resource. (2010)
  • George Chynoweth
    A US Military Agency
    Charlie is personable, with a ready sense of humor. His technical skills are superb: he can see the big picture and develop all the intricate details to bring it all together into a functioning system. 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.

    "I've been working in the IT industry for over 20 years and in all of that time I've never met anyone that I would recommend more highly than Charlie Arehart.
    Charlie simply never stops delivering on ways to help and improve things for his clients. Countless times we recevied advice from Charlie which has simply left us saying - "wow, why didn't we think of that!"
    Charlie is honestly as good as it gets!"

    Thanks for all your help. The server has acted flawlessly since we worked together. I'm so glad you were there with that service. Couldn't have done it without you, was a pleasure, and I always tell CF users about you. (2009)
  • Michaela Conley

    I have known Charlie for more than a dozen years. I have found him to be detail oriented and methodical in his approach to creating solutions to complex multi-faceted challenges. His ability to communicate without the use of technical jargon made working with him an exciting opportunity to learn from one leading experts in his field. (2008)
  • Byron Shank
    Home Reserve, LLC
    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.

  • 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
    Centric Web, Inc.
    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. It isn't often that when you pay for the extra support you actually get someone who really knows his stuff and is willing to really work through the details with you. (2008)

    "You were a life saver! Really, the server is performing better than when we purchased it. We hit a record today with # of simultaneous users and stand to do well in sales." (2008)
  • Kevin Hamada
    Director, Systems Technology (for a Fortune 100 company)
    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. Not only did Charlie find and resolve our bottleneck issue, but he also helped establish a preventative maintenance plan. The results of his interactions enabled us to move from having performance bottlenecks on our web servers every hour to servers that are now running smoothly.

  • "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.",

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",
