    I have been in sales for 5 years, and absolutely love working with people.   Working ethically and transparently are important core values that I never stray from.

    I enjoy being outdoors with my two six-year-old kids.  We go hiking, biking, and picnicking as much as possible.

    When I have extra time, I volunteer at Milwaukee Parkside School of the Arts.  Once a year, I take a weekend off and go to Devil's Lake State Park to camp and hike with my dog.

    I have been selling high-line European automobiles since 1976 with leasing as a specialty.

    My hobby is collecting miniature art.

    I am an avid runner that belongs to The Badgerland Strides Running Club, and I participate in races throughout the year.

    I also enjoy sailing.  I was a member of the Milwaukee Community sailing center for years and owned my own boat.

    When I have free time, you will find me in Door County.
