Extremely thorough, down to the last detail
Mr. DeVan is an incredibly thorough and understanding attorney who makes sure he turns over every stone. He went to great lengths to make sure he had all the information about every angle of the story, and in doing so, he made sure we were always a step ahead. He is an honest, straight-forward person and is highly recommended. Many thanks to Mr. DeVan and his firm!

Excellent Attorney
Mark is a good listener. He and his team conduct thorough background and research. As a result, his oral and written arguments were well structured. It was clear to even a casual observer how state and federal laws did or did not pertain to the facts and information brought forward in the case. Mark also did an excellent job keeping me informed of all developments and promptly returned my phone calls. Additionally, he maintained a positive, upbeat attitude which was invaluable. I would not hesitate to use or recommend him or his firm.

Endorse Mark
Criminal defense Attorney | May 29
Relationship: Fellow lawyer in community
"I endorse Mark. He is a highly skilled attorney that is well respected in the legal community."
Criminal defense Attorney | Mar 29
Relationship: Fellow lawyer in community
"I endorse this lawyer wholeheartedly. I had the opportunity to work with Mr. DeVan on significant matter because I knew the defendant well. Mark is obviously a proficient and dedicated lawyer. The case was a complicated one, involving numerous motions, including pre-trial motions and briefs, a pre-trial hearing and a trial of about 7 days over most of 2 weeks. Mark worked effectively with the client, his family, other lawyers, and investigators and consultants. He managed the case excellently throughout, including the gathering of evidence, preparing for witness testimony and cross examination, jury selection, and conduct of the trial itself. He showed excellent judgment about what aspects of the case deserved extra attention and which ones didn't. His fine work and the successful outcome are consistent with what one would expect of one of the finest criminal defense lawyers in the area. I have since made referrals of others to Mark and have received very positive reports back."
Criminal defense Attorney | Feb 24
Relationship: Worked together on matter
"I first knew of Mark DeVan by reputation. As I got to know him better and then to work with him, I realized that his reputation as an excellent attorney was well deserved. I would have no reservations on recommending him to anyone who desired his services."
