I grew up in Batesville, born and raised. My wife Casey and I both work as teachers for the Batesville Community School Corporation. She is a second-grade teacher at Batesville Primary School and I teach social studies at Batesville High School. We have 3 children, 13-year old daughter Mackenzie, 11-year old son Cameron, and 7-year old son Colton. We love this community and are grateful for being a part of it. I want to help provide real estate services for those that seek to live in and enjoy the abundant amenities that Southeastern Indiana has to offer. Whether it’s a community event, festival, concert, or parade, Southeastern Indiana provides endless opportunities for all those that call it home. Whether that involves moving to or moving from, I welcome the challenge, will embrace the opportunity, and will be honored to serve and represent others in their journey to find the place they can proudly call home.

There is no better place to live and work than right here in Southeast Indiana! That’s not just a sales pitch. Over the years, my profession has given my family the opportunity to travel and live in a number of great communities. In the spring of 2020, we were given yet another opportunity to relocate. We couldn’t do it. Southeast Indiana is more than a place you live. It’s a place where you want to settle down and make a home.

I became a real estate agent for two reasons. The first was to find a profession which would allow me the opportunity to give back, volunteer, and invest in making our community a better place to live. The second reason I became a real estate agent is that I love helping people make their dreams come to life.

Every day is an exciting new opportunity to help others discover and make Southeast Indiana their home too. It is my mission to help you not just purchase a house, but to help you discover and create a home.

My commitment to you is to give you a simple home buying experience with the honesty and open communication you would expect from someone entrusted with helping you discover your home. Give me a call today, and together let’s dream about your future in Southeast Indiana. I am a member of the National Realtor’s Association, the Indiana Realtor’s Association, the Southeast Indiana Board of Realtors, the Metropolitan Indianapolis Board of Realtors, and the Project Management Institute.
