Bob’s clients appreciate that he gets to the point. He is concise, direct and does not waste their time. They also value his dedication not only to providing outstanding legal counsel, but also for respecting their budgets. Whenever possible, Bob’s objective is to help his clients avoid disputes by identifying and resolving problems and obstacles early on. However, when disputes do arise, he has also been able to build bridges to settlement, on multiple occasions, in scenarios where the conflict was so acrimonious that even his client believed intense litigation was the only recourse. As a result of Bob’s innately creative problem-solving skills, he has taken seemingly impossible situations and helped make resolution possible.

Prior to practicing law, Bob served as an analytical chemist in the oil and natural gas industry, where he conducted analysis on soil and water for environmental contamination, directed tests on fuel recovery, and designed a fuel recovery system.
