    Veterinarian & Owner

    I arrived in Sullivan fresh from the University of Minnesota Veterinary School in 1983.  I am originally from Sheboygan County.  I graduated from Kewaskum High School and the University of Wisconsin - River Falls.

    My wife Susan and I have been married since June 1988.  Sue is the principal of St. John the Baptist school in Jefferson.  We have two children.  Joe is in his second year of graduate school in electrical engineering at Notre Dame.  Anne is in her first year of graduate school at the University of Wisconsin - Whitewater studying speech pathology.

    We have four furry members in our family.  Gertie and Maizie are our cats, Rusty is our horse, and we just added to our family a golden retriever puppy named Libby.
     
    My hobbies are gardening, cutting firewood, dabbling in woodworking and traveling.

    There are so many aspects of my job that I enjoy.  I love the endless variety of patients and clients.  I truly love the interpersonal contacts we make.  If I had to list my favorite thing, it would be delivering babies of all species.

    I have the best job in the world and am truly blessed to be a veterinarian, husband and father.
