Our Veterinarians

Our friendly and dedicated doctors and staff look forward to meeting you and your family!

Dr. Eric Howlett

 Dr. Eric was born and raised in Texas. Before finding his true calling as a small animal veterinarian, Dr. Eric  had a very broad science background including a Ph.D in Biochemistry and Cell Biology with Post-Doctoral training in Radiation Oncology and Public Health. After traveling widely in areas as varied as Nepal, Rwanda, Ecuador, and Tanzania, he has found a long term home in the Mazomanie area, graduating from the University of Wisconsin-School of Veterinary Medicine in 2015.  He has practiced in the area the past 2 years.

 He and his wife enjoy their free time on their small farm homestead caring for their menagerie of cows, goats, chickens, dogs and cats.

 Dr. Eric has certification and a passion for a fear free approach to reduce stress and anxiety for his dog and especially cat patients. He particularly enjoys building relationships with pets and their owners to better understand their needs and allow him to give the best advice tailored for that particular individual, whether that be the most pampered family pet, an old farm cat or dog, or the prized hunting dog or show cat. After getting to know you and your pet, he prefers to follow a shared approach for deciding on the best preventative, surgical, or medical care for your pets.

Dr. Liz Jacka

 Dr. Liz Jacka is a 2010 graduate of the University of Wisconsin School of Veterinary Medicine. A native Wisconsinite, she grew up in Kenosha and earned her undergraduate degree in Biology at UW-Parkside before moving to the Madison area in 2006. Since graduating from veterinary school, her career has revolved around practicing as a small animal veterinarian and teaching at the UW Veterinary School, where she enjoyed mentoring the bright new members of the profession.

  Dr. Jacka is passionate about wellbeing for both animals and humans. Her favorite thing about being a veterinarian is helping preserve the special bond between people and their beloved pets by getting to know you as an individual and offering medical solutions to support the best quality of life for your furry companion. A teacher at heart, she focuses on helping pet parents understand what is going on with their pet in order to make informed decisions about their care. Her special areas of interest include clinical pathology, endocrinology, animal behavior, and senior pet wellness and end-of-life care.

 In her free time, Dr. Liz loves running, reading, crafting, hiking, kayaking, and anything that involves the great outdoors. She and her husband enjoy exploring the world and have summited mountains together in the US, Canada, Europe, and New Zealand - with more adventures ahead! At home in New Glarus, WI, you can often find her in her garden or out hiking the Ice Age Trail with at least one of her three Australian Shepherds (Zoe, Cria, and Badger).

Dr. Mark Baenan

  Dr. Baenen graduated from the University of Wisconsin School of Veterinary Medicine in 1995. He began his career as a large animal veterinarian at River Valley Veterinary Clinic.  In 2003 he decided to pursue his small animal interests and, along with Dr. John Dally, started Spring Green Animal Hospital.

  Dr. Baenen has an interest in Dentistry, General and Orthopedic Surgery. He has special training in a surgical technique for the common orthopedic hindlimb ACL (cruciate ligament) injury for large dogs called the Swivel Lock technique. He also has been able to help many older dogs with progressive hindlimb weakness improve their quality of life with a simple procedure administering a steroid into the epidural space.

 He met his wife Nancy while in college.  In 1999 they started their family and have two daughters, Harper and Isabella, and a son Cameron.  He also shares his home with a blind Jack Russell Terrier, 'Milo,' and 3 cats (Cooper, Tucker and Carl).  In his spare time Dr. Baenen enjoys tinkering in his garage, expanding his knowledge, and building things.  He recently obtained his pilot license and built his own small airplane!
