Welcome to our website!

Karen grew up on a farm near Monticello, Iowa and Steve in Cincinnati, Ohio.  We met while working at hotels in Colorado, married and chose to raise our children closer to family in Iowa. 

From 1993 through 2002, we owned and operated Supper Club 528 in Cascade, Iowa.   Our daughter, Hannah, was 12 months old when we took over the restaurant and our son, Elliott, was born 2 years later.   The restaurant enabled us to build a successful business by providing quality food and service to our customers.  Although successful, running a restaurant can be taxing on raising young children which lead us to pursue another career.  In 2002, Steve obtained his real estate license and Karen followed a year later.  We moved our family to Marion and our children thrived at their new schools while also knowing that mom and dad would be home each evening to tuck them in bed.   

Service has always been the cornerstone to our success and continues to play a major role in our real estate career.  We differ somewhat from other "teams" in real estate by the fact that each client of ours is "our" client, not Steve's client or Karen's.  Through the years in business we have learned that we each have our strengths and when combined, we are able to provide superior knowledge and service to everyone.  

Whether buying or selling your first home or your fifth, we would welcome the opportunity to guide you through the process of the entire transaction knowing that your best interest is ours also.  

Welcome to our website and we look forward to hearing from you!
