Katrin Witz, DVM, Practice Owner

Dr. Katrin Witz was born and raised in Germany. She has always had a great interest in animal health. Growing up she gained experience by volunteering at shelters and veterinary clinics, as well as helping the elderly care for their pets. After moving to the US, she worked for many years as a Certified Veterinary Technician at a busy, well-equipped small animal clinic.

Dr. Katrin received her Doctor of Veterinary Medicine Degree at the University of Wisconsin, School of Veterinary Medicine. In August 2014 she purchased Oconomowoc Animal Hospital from Dr. Lauridsen. She looks forward to serving the community by providing compassionate veterinary attention to all patients. She values patient care, client education and strives to practice with integrity, treating each animal as her own. She treasures the human-animal bond and tries to guide the owner through all stages of their pet’s life by providing preventive care, medicine, dentistry services and surgery.

Dr. Katrin stays current with the ever-evolving field of Veterinary Medicine by attending continuing education meetings and being an active member of the WVMA (Wisconsin Veterinary Medical Association) and the AVMA (American Veterinary Medical Association).

When not at work, Dr. Katrin likes to spend time with her husband, 2 children, along with their menagerie of furry, feathered and scaly family members. Together they enjoy hiking, camping, kayaking and exploring the great outdoors.

Kirsten Zellmer, DVM

Dr. Kirsten Zellmer is a 1995 graduate of the University of Wisconsin School of Veterinary Medicine. She started her career by working in Sullivan for three years, followed by an 18 year stint at Bay East Animal Hospital, an AAHA accredited practice located in Green Bay, WI. The move back to this area in 2016 came after her husband was promoted and relocation was part of the the package deal She joined our practice in October of that year. Dr. Zellmer has a special interest in feline medicine and the effects of nutrition on health in general, and she also enjoys the detective work involved in figuring out a complicated case.

Dr. Zellmer has four grown children, three girls and a boy, one of which is married and the other three who are working their way through college and post-graduate study. “Empty nester” is not exactly an appropriate term–along with her husband, she shares the house with a nutty old English Springer Spaniel named Rosy, a mildly psychotic/brain damaged part squirrel grey cat named Ember (“Kit”) and a funny little Guina pig named Lily (“Pigget”).

Dr. Zellmer loves spending time in the oudoors, especially doing things like gardening, camping, hiking and traveling with her family. She is a strong believer that keeping the environment healthy is a good way to keep people and their animals healthy as well.

She loves working with reptiles, birds, and small mammals, too.
In her free time, Dr. Lauren, her husband and two young sons love to camp, travel, hike, and watch wildlife.

Sarah, Technical Team Member

Sarah’s love and fascination for animals started when she was very young with her own family pets. Not only did she push her cat around in a baby carriage and train the family dogs, she bred hamsters and guppies for the local pet store. As a teenager she began rescuing birds and other local wildlife. She also had summer jobs at local horse stables and the Michigan City Zoo. Her interest didn’t wane as she continue into her college years where she obtained a Bachelor’s Degree in Psychology with an emphasis on Animal Behavior and a minor in Biology. Sarah also had some amazing experiences working for John Ball Zoo and volunteering at wildlife centers in Grand Rapids during the summers.

After college, Sarah moved to the Milwaukee area and worked at a pet store, ran her own pet-sitting business and volunteered for a local no-kill shelter. She gained valuable experience working at another large veterinary clinic for 13 years before coming to work at Oconomowoc Animal Hospital in 2014.

Sarah is married with 2 wonderful children and a house full of furry, feathered and scaled family members.

Laurie, Client Care Specialist

Laurie has been working at the front desk of Oconomowoc Animal Hospital since September 2002. She loves animals and enjoys working with dogs and cat. She also enjoys seeing our new reptile friends. One of Laurie’s favorite things at OAH is interacting with pet owners. She has made many wonderful friendships over the years.

Amanda, Client Care Specialist

Debbie, Client Care Specialist

Debbie has been working in various veterinary clinics for nearly all of her adult life and has been at OAH since 2016. She enjoys critters of all shapes and sizes, and if she’s not at home with her 4 Golden Retrievers, 2 cats and 24 chickens, she’s enjoying her work at our veterinary hospital! She always has fun exchanging stories of life with pets with our wonderful clients.

Debbie’s golden boys keep her running, as they keep busy with agility trials, field and obedience competitions, and occasionally play “pretty dog” at conformation shows. When she gets some time to herself, Debbie enjoys gardening, which can be challenging when the dogs try to help her!

Tasha, Client Care Specialist

Tasha has always had two loves–animals and art. In 1995 she joined those two passions and became a professional pet groomer. She enjoyed making pets feel better and look great. Over the years, the physicality and strain of dog grooming took a toll on her. Tasha and her husband, Mike, decided to start a family, and she transitioned to the front office in veterinary service. She joined Oconomowoc Animal Hospital in summer of 2019.

Tasha’s priorities remain her family (both furry and non-furry), feline behavior and stretching her creative abilities when she finds time. She is happy to have found a home at OAH where the like-minded environment shares her love of helping people and animals.

Kristi, Client Care Specialist

Kristi moved to Oconomowoc in 2020. She has lived in five states over the past 20 years and finally settled in Wisconsin near her husband’s family. She has a MSW (Master of Social Work) from Nebraska and worked as a social worker before taking time off to be home with her two boys. Her sons are now in college and she wanted to do what she loves best, helping people and sharing their love of pets. She joined OAH in 2021.

Kristi and her husband have 2 dogs at home, Shih Tzus Lacey and Stella. When she’s not at Oconomowoc Animal Hospital she enjoys reading, gardening and traveling to see friends.

Heike, Administration

Heike joined Oconomowoc Animal Hospital in November, 2014. She was born in Germany and lived there until June of 2010. She has had different jobs throughout her life and most enjoyed a professional office environment. She is working on many office and administrative projects at OAH.

When Heike came to the United States she spoke very little English and has worked very hard to learn the language. Heike is lucky enough to see her grandchildren daily and when not at work she enjoys exloring her creative side creating art projects experimenting with different types of medias, reading, gardening and spending time with her husband, Ralf, and their cat, Pirate Annie.

Jack

Jack spent a few days with us when he developed his first urinary obstruction. While we do our best to control their pain and discomfort, it’s not always fun for them to be here. Once he was feeling better we sent him home. He re-obstructed within 24 hours and his family was at a crossroads.

We gladly took Jack back in and he’s been a part of our OAH family since June of 2017. He has 20+ women who fawn over him daily, feed him his special urinary food, rescue him from dogs, bend to his every whim and listen to him complain loudly when he thinks he’s dying because we’re not punctual enough with his dinner (his opinion).

He has several beds throughout the clinic and relishes spending some occasional supervised time upfront. He can only be in our reception area under very close supervision because he likes to go shopping. His favorite is the largest bag of Hills I/D dog food and he will chew his way into the bag in a matter of seconds!

You can frequently find Jack on our Facebook and Instagram pages because we just can’t stand how cute he is.

Clarence

Clarence the bearded dragon joined our OAH family in June of 2019 after he was surrendered to a local pet store. We don’t know much of anything about him except that he is a super chill, friendly boy, unless we try to feed him kale (see more about that below).

His tank is in the office so he can watch some of the hustle and bustle of daily life in the clinic. He gets especially excited when kitties spend some time in the office. He loves when kids come to visit him and he likes to show off his bug-catching and eating skills for his visitors. He loves spicy veggies like mustard greens, cilantro and arugula along with the occasional blueberry, strawberry and peppers, but if we even try to slip a small piece of kale in with his hand-fed salad, he will go and pout in the corner.
