Client Testimonials

"Having had the occasion to require counsel and legal representation recently, I turned to Sterling for clarification and professional guidance through a most challenging obstacle. Solid information and continual, trusted encouragement was provided to me throughout the entire experience and the results of the case left me grateful for his expertise and interest. His knowledge, skill and of course his personal attention to his clients allow me to recommend him with confidence."
"I found myself on the wrong end of a lawsuit. . . . Sterling handled my claim and to be honest I am so happy he did. Within weeks we had a settlement offer . . . . they offered a settlement that had little impact on my life, no out of pocket expenses and it [was] dismissed. I am thrilled with his ability to see through the facts of a claim and relay that to his opposing counsel and effectuate a settlement I otherwise do not think I would have got. I cannot say enough good things about Sterling. He is personable, approachable, knowledgeable, funny, and talented as a lawyer. . . . . I highly recommend him as a lawyer and his firm is great, they give their time and do not just give you time you are paying for but had contact both on an amicable (human) basis, as well as great legal communication."
