About me

     I focus my practice on the areas of OVI/DUI criminal defense and Social Security Disability. I graduated from Salmon P. Chase College of Law and was licensed to practice law in the state of Ohio in 1998. While earning my degree, I was honored by being chosen by the American Inns of Court, an honor given due to my committment and aptitude toward litigation.

     I am licensed to practice law in Ohio State and Federal Court. I have worked in both the public and private sector and my background is comprised of experience representing clients in many areas including: criminal, civil, property, probate, juvenile, business and family law. I have litigated cases in Hamilton, Clermont, Butler, Warren, & Brown Counties.

     I am passionate about my work and my clients best interests. I understand how trouble with the law can wreak havoc on every aspect of your life: family, employment, day-to-day driving privileges, and future endeavors, be it personal or employment related. I want to help you prevent any further interruptions by this matter to your life. My ultimate goal is your satisfaction, a goal which I work diligently to achieve.
