Client Comments

"Mark Harrison is a seasoned veteran who is easy to work with, but who provides knowledgeable, practical, and straightforward legal counsel to clients involved in dealing with difficult legal issues. He has the highest level of honesty and integrity. Unusual among lawyers I have dealt with is Mark's candid approach in counseling clients if he or his firm is not, in Mark's viewpoint, the best lawyer or law firm to handle a particular assignment; he will suggest alternative counsel. This makes an initial call to Mark a good decision by anyone needing legal help."
