"I've known Mark since 2007 and he has done both my corporate and personal taxes since then, and I must say that since 1970, I've had only 2 other CPAs and they were very good accountants, but Mark is by far the best of them all. He is always accessible and has acquired extensive knowledge about oil and gas tax matters which are beyond most corporate tax problems of today."
- W. G. Horst, President, Twin Western, Inc.
“I have known Mark since 2005 while working with him in the forensic accounting department at Clifton Gunderson. Mark was very passionate about accounting, smart and had a very impressive work effort. Our career paths have gone in very different directions since then, but when I started my own business and heard Mark had started his own accounting firm, I gave him a quick call, and he didn't disappoint. In two ten minute phone calls (one on a Sunday morning) he has given me a custom strategy to help grow my business through proper tax strategy and financial management. He has reduced my operating costs while providing tremendous value as a consultant and look forward to working with him.”

"Mark has a exceptional knowledge of the Texas tax laws and he is very easy to deal with. He really took the burden away from our stressful and complicated tax situation we were dealing with. He is not only a fantastic CPA, but he is even a better person. 1000% The best CPA I have ever worked with."
