About Us

Bob founded the Robert H. Keller Company in 1950 after working in construction management. He started small, with a two-flat building. He knew from the start that he wanted his business to be known for honesty, integrity and service. Over the years, he developed and brokered many properties in and around Madison. He kept his business operations small, though, to maintain that friendly, midwestern service he was known for.

When his three sons joined, the company changed its name to Keller Real Estate Group, and expanded to include more property management, real estate sales, financing and development.

He has been the President of the Realtors Association of South Central Wisconsin (1957) and received the Realtor of the Year Award (1968).

Bob is an avid three-cushion billiards player and recently opened the Madison 3-Cushion Billiards Club.

Dan has been managing properties for thirty years. He will dispatch the maintenance team to take care of any building or appliance problems you might run into as a resident. Dan received his Accredited Residential Manager (ARM) certification from IREM in August 2005.
