Real Estate

Excellent resource for HOA’s to draw upon. Experienced, highly competent and very responsive. I have, and will continue to recommend Mark Biddison.

Civil Litigation

I’ve known Mark Biddison for over 30 years, he is a fine man and a great representative. He is always prepared! You’ll get the truth even when you don’t want to hear it. His advice and experience are sound. He is very responsive and never left us hanging when we had concerns. He always had detailed information about why we should take a particular path when we had questions. His ability to remain calm and clear when we were very upset was critical to feeling we were in good hands.
