About me

With over 25 years of law practice I am stil very driven to provide the highest quality legal representation of our clients with a compassionate understanding of the often volatile and stressful life events which my clients are enduring.

I enjoy traveling with my family and spending down time at the Lake where we enjoy an active lifestyle of boating, skiing and fishing.

    I shared office space with Mark and he was always offering helpful advice. His staff is AMAZING. He is very good at client contact. Great family law attorney especially if you have a good deal of assets. Plus he is a wonderful person. Definite credit to the Clay County Bar Association!
