Mark Diehl Sullivan

Outstanding attorney - showed integrity, grit, extensive knowledge and intelligence, humility but with strength and aggressivness. Have worked with multiple other attorneys... Mark's responsiveness and attention to detail were by far the best. These qualities along with the outcome of the case woul...d definitely lead to using him again and recommending him to others.

We have hired Mark on 3 separate occasions; twice to review minor issues for us, and once for an extremely large problem that was potentially devastating. We last hired Mark to help us (and another great attorney, Richard R. Thomas, of Scottsdale, AZ) with a complex commercial litigation case involv...ing a $Trillion multinational corporation with unlimited legal/financial resources. We have known other lawyers with big egos and control issues. Not Mark. He is great to work with! Mark collaborated with our other attorney extremely well. Additionally, he welcomed our input as clients, and worked closely with us every step of the way. This was a particularly complex and challenging case that required attorneys to do detective work and extensive research. Whatever Mark didn't already know, he learned or figured out; he didn't just stick with strategies he was familiar with or had previously employed. Mark was impressively thorough! Further, his preparation for hearings, depositions, etc. was not only noteworthy, but admirable. Mark's high levels of professionalism, ethics, and true integrity served us well; and, we believe, added even more credibility to our case in the eyes of the judges. It is our opinion that any judge, jury, arbitrator, or mediator will not only like Mark, but, most importantly, really respect him. Mark's billing practices have been very fair, and he has deserved every penny. Mark has heard our "thank you's", witnessed our tears of joy, and has felt our genuine hugs... and there is still gratitude we have yet to express for what he has done for us. While we are hoping to never again be involved in any type of lawsuit, we would, without hesitation, put our trust in Mark D. Sullivan again.

The case Mark handled for me and my husband was a breach of contract, fraud and racketeering case involving multiple plaintiffs against a modular homebuilder that had closed up shop, leaving us all with partially-completed but fully-paid-for homes. Mark's representation of us included a hearing in C...heyenne in which we were seeking a preliminary injunction freezing the defendants' assets which were in danger of being liquidated. Ultimately, thanks to Mark's expert advice, we elected to have him guide our case through mediation, and we successfully avoided going to court. Without Mark's tireless efforts, his impeccable professionalism, and--perhaps most importantly--his vision in bringing racketeering charges to bear in the case, our outcome would likely have been very different. We remain profoundly grateful for Mark's comprehensive evaluation of our complaint, his faith in the strength of our case, and the herculean effort he exerted on our behalf. We recommend him wholeheartedly and without reservation.

As a member of a team to find a new Attorney to represent our Not for Profit organization, I was pleased to bring Mark Sullivan's name to the table. We did engage Mark's services and for the past 6 years he has proven his value over and over. His diverse knowledge and expertise continues to provide ...us with superior guidance through the complex process of negotiating with Lenders, Title companies, member disputes and contracts. It is Mark's "tough but kind" demeanor that has kept a calm perspective in even the most uncomfortable and challenging situations. His timely responsiveness, absolutely fair billing, and integrity have confirmed our decision in choosing Mark for all of our legal needs and has inspired us to unequivocally recommend him to members of the general public.

Mark D. Sullivan has represented our company for the past six years, enabling resolutions on various legal disputes with some of our customers in the hardware/construction arena. Prior to retaining him for legal counsel, we did our "do diligence" and discovered how extensive his background is in com...mercial litigation, including complex environmental matters. We immediately knew that Mark was the attorney to represent us concerning legal issues within the construction industry. In one extremely difficult case in particular, our company prevailed in District, as well as Supreme Court, with an affirmation in full of the District Court's judgment. We were awarded damages in full, including interest and attorney's fees and costs. This case was unusually challenging and required extensive research, writing time, and attention to detail. It is very impressive to watch Mark in action before the Courts. He always comes prepared using his skills and experience to persuasively present and argue the matters at hand. We have recommended Mark on several occasions to others requiring legal counsel. He is definitely the attorney you want representing you and standing by your side.
