Your Local Trusted Advocate and Counselor

With each passing year, new legislation and court decisions further alter the legal landscape. Although the pace of change will not let up, you can be confident that you will confront these challenges and achieve the best possible results with us as your advocate.

What you can also expect is outstanding customer service. You will have your communications promptly returned and I will always make myself available to answer your questions. You can also expect to know the status of your case at any point in time through electronic access to case files and periodic status updates. As a result, you will always know what shape your case is in and where it is heading.

The Attorney-Client Relationship

From the first time we meet to the last, you can be certain that you will always be treated with courtesy and respect. Everything you tell me will remain confidential and will be heard without judgment. You also deserve and can expect zealous advocacy.


“[A]n advocate, in the discharge of his duty, knows but one person in all the world, and that person is his client. To save that client by all means and expedients, and at all hazards and costs to other persons, and, among them, to himself, is his first and only duty; and in performing this duty he must not regard the alarm, the torments, the destruction which he may bring upon others.” 

- Lord Henry Brougham,  TRIAL OF QUEEN CAROLINE 3 (1821).
