Why did you become an attorney?

To help people start and run their businesses profitably and with the least stress possible. The law and lawyers can be very intimidating, especially when a client's closely held business is at stake. I try to help people in a way that helps them both understand the law and feel comfortable and confident in dealing with it. I find it especially rewarding when I've successfully navigated a complicated business or real estate deal for my clients.

What experiences (work and personal) help you to be a better attorney?

Working with a variety of people under all sorts of circumstances, in varied businesses, and with differing resources and skills has helped me to become a better attorney and person. In addition, I have focused my entire legal career on closely held business and commercial real estate and business issues, giving owners the information and advice they need to be successful  My dad owned his own business, so I understand that my clients can't easily separate their work from their personal lives. As a result, I address clients' issues in a way that recognizes the business, real estate, legal, and personal concerns.I was one of the first lawyers in Ohio to be certified by the Ohio State Bar Association as a Specialist in Business, Commercial and Industrial Real Property Law. In addition to my law degree, I have a Masters Degree in City and Regional Planning from The Ohio State University which has helped me in my real estate work.

What made you choose your primary specialty focus of law?

Closely held and family businesses and their owners have unique challenges and problems but some lawyers and larger firms aren't attuned to these issues and can't relate to them. I have over 30 years experience helping small business owners navigate legal issues and nurture their businesses. In addition, I am the son of a small business owner and feel I have unique insights and skills because of the real-life business lessons I learned from my father as well as from my clients . My real estate focus began as a natural extension of my interest in business and city planning but has grown to include an interest in all aspects of commercial real estate. To further hone my real estate law talents, I've participated for many years on the Columbus Bar Association's Real Property committee and served as chariman of that committee for two years. I was one of the first lawyers in Ohio to obtain a Certified Specialist designation from the Ohio State Bar Association in Business, Commercial and Industrial Real Property Law.

Describe your personal interest and hobbies.

I live in Westerville with my wife of 36 years. We are blessed with three daughters, one of whom is married and has blessed us with two beautiful granddaughters. In my free time, I enjoy spending time with my family, riding my motorcycle, playing guitar, and listening to music.

Describe your charitable activities.

I have long been active in community and civic matters, including church and ministry activities, city government, and chambers of commerce. I am heavily involved with Rotary, the world's largest international service organization, focused on accomplishing charitable and service projects that address important world and local community needs. I’ve served as a District Governor and club leader for Rotary, implementing humanitarian programs for Rotary Clubs and The Rotary Foundation, which funds Rotary's efforts in 200 countries. I currently serve as Rotary Coordinator, helping 12 Rotary districts in six states effectively serve their communities and the world.
