Mark J. Sullivan is widely considered the preeminent criminal defense attorney in Riverside and San Bernardino County Courts, and has been for over two decades.  

Esteemed trial judge Jack Ryan put it this way, "Mr. Sullivan is the consummate professional.  He is held in the highest regard by members of the Riverside County bench.  He is well respected by the local prosecutors and defense bar.  I have worked with and have had the opportunity to see several great attorneys in these past 35 years.  Mr. Sullivan is the best I have seen in Riverside County - and he ranks with the best criminal defense attorneys I've ever seen anywhere." 

Mr. Sullivan is one of only twelve Certified Criminal Law Specialists in all of Riverside County, California, and the only one in Palm Springs. He was recently voted the best criminal defense attorney faced by prosecutors in a local San Bernardino County District Attorney's office. He is Past-President of the Criminal Law Committee of the Desert Bar Association, and has served as a lecturer, author, arbitrator and judge pro tem.
