About me

Thank you for taking the time to read my profile.  You can read more about me at  On a daily basis, I work with clients to understand and resolve family law disputes, be it a complex divorce or simple dissolution, interstate child custody or routine child support matter. I was former Chief of the Criminal Division of the Geauga County Prosecutor’s Office which provided me trial experience which is invaluable.  I use this experience on a daily basis.  As an experienced former assistant county prosecutor and graduate of the National College of District Attorneys, Career Prosecutors Course, I believe I can offer clients the breadth of experience to evaluate and understand legal disputes with the gravest of consequences.
