Dr. Ellen Richardson
Dr. Ellen Richardson was born and raised in Massachusetts and moved to Madison to attend school. She fell in love with the Madison area, and quickly determined that Dane County is where she wanted to put down roots. After graduating with Honors from the University of Wisconsin-School of Veterinary Medicine in 1992, she spent the next ten years mentoring with other veterinarians, until opening Mazomanie Animal Hospital in 2002. Dr. Richardson and her husband Ken live in Cross Plains and have two school aged sons. They share their home with four cats, (Henry, Stripes, Bandit and Toby), a miniature poodle, (Belle) and a chihuahua (Sylvester). Dr. Richardson enjoys getting to know clients and their families while providing individualized medical care to pets over their lifespan. Her practice interests include client education, soft tissue surgery, internal medicine, and dermatology. In her spare time she enjoys gardening, reading, and kid-related activities.
Dr. Didi Heisler
Dr. Heisler has lived in Washington DC, Los Angeles, and Lawrence, Kansas, among other places. She moved to Wisconsin in 1998 and took a job as a biomedical research administrator at UW-Madison before going on to pursue her lifelong dream of becoming a veterinarian, graduating from the University of Wisconsin-School of Veterinary Medicine in 2006. She joined the Mazomanie Animal Hospital as a part-time veterinary associated early in 2014. She also teaches biology part-time at Madison College. She lives in Middleton with her husband and two school aged sons as well as their coonhound mix, Shelby and Shelby’s cat, Layla. Dr. Heisler’s practice interests include parasite prevention, dental health and oral surgery, and helping pets achieve and maintain a healthy weight. In her spare time she enjoys biking, running, and cross country skiing as well as cooking and baking.
Kathleen Johnson, Client Care Specialist
Kathleen earned her BS in Art from UW Madison, and worked locally as a designer for 18 years. Her experience with the Mazomanie Animal Hospital began first, as a client, appreciative of both the staff and the practice philosophy. Kathleen then joined us in 2015, fulfilling a desire to reconnect with Veterinary Hospital Support, after managing a veterinary practice in California for 15 years. Kathleen lives in Mt. Horeb with 4-year old “Harry” feline, and youngster “Sofie”, canine. She enjoys gardening, sewing, and hiking.

*** In Memoriam ***
Hawk came to Mazomanie Animal Hospital in 2014. Since then, he stole the hearts of clinic employees and clients alike. What everyone noticed first about this 12 year old Maine Coon, was his striking blue eyes and “larger than the average housecat” proportions. He enjoyed greeting visitors over the front counter, especially if they were buying food. He made numerous supervisory walks around the clinic every day, to make sure we were all working to the best of our abilities. He was the clinic specialist in chair stealing, and napping on top of work papers. In his spare time, Hawk’s favorite hobbies were sleeping, eating, snuggling, and purring. We miss him greatly.
Please stop in for a tour, visit, or make an appointment. We have numerous years of experience in providing for and caring for your companion animals.
