    Veterinarian & Owner

    I grew up in Mukwonago and received my undergraduate degree in Biology from Purdue University.  I then attended the University of Wisconsin School of Veterinary Medicine where I graduated in 1999.

    I worked for several years in the Milwaukee area before coming to Sullivan in 2003.  I became an owner of Sullivan Veterinary Service in 2005.

    My favorite aspect of being a veterinarian is that no day is ever the same.  I love the variety of cases I work on everyday.  I have a special interest in orthopedic surgery and feline medicine.  

    I currently reside in Hebron with my husband and our 2 children.  Our family also includes two dogs and three cats.

  • Richard L. Loof, DVM


    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 teaches of St. John the Baptist school in Jefferson.  We have two children. 

    We have four furry members in our family.  Luna and Maizie are our cats, Rusty is our horse, and a golden retriever 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.

  • Aliceon M. Eckerle, DVM


    I was born and raised in Waukesha, and started working at a veterinary hospital while I was in high school.  By that time, I realize that I wanted to work with animals in some way.  I received my undergraduate degree at UW-Parkside in biology and then went on to veterinary school at Ross University in St. Kitts (located in the West Indies).  I graduated in 2011 and have been practicing small animal medicine ever since.  I started working here at Sullivan Veterinary Service in 2018.

    I have been married since 2014 and currently live in North Prairie with our 12 year old son.  Of course our home is full of pets; 3 dogs (Kenzie the Westie and Isaac & Bruno the Papillons), 2 cats (Alex & Olivia) and 2 reptiles (Rango the bearded dragon & Monty the ball python).

    I love getting to know my patients and their families and watching them go through different life stages.

    When not at work, I'm usually taking care of my menagerie of animals.  My other hobbies include cooking/baking and archery.  But most nights are spent cuddling on the couch with all my furies.

  • Lea Ann Murack

    Practice Manager

    I grew up on a dairy farm in the Town of Concord and have always enjoyed being with animals.  I have known the doctors here at Sullivan Veterinary Service since I was a little girl.

    I graduated from Lakeside Lutheran High School in 1986, and came to work here at Sullivan Veterinary Service in 1994.  I have always wanted to be involved with veterinary medicine, and since I also enjoy accounting, this has been the best of both worlds.

    I still live in the Town of Concord with my husband and our daughter.  We share our home with our Brittany Spaniel, Lucy and Fiddler, my horse.

    Veterinary Assistant

    I began working for Sullivan Veterinary Service in 2012.  Working with animals has always been a passion of mine.
