The daughter of veterinarian and hospital founder Dr. Herbert Preiser, Dr. Kristine Preiser has been the medical director of Preiser Animal Hospital since 2007. Kristine played Division I soccer at Iowa State and at the University of Montana where she also earned a BS in Biology with an emphasis in Zoology and a minor in Philosophy. Kristine attended Ross University School of Veterinary Medicine and then completed her clinical year at Washington State University where she graduated in 2007. Before becoming a veterinarian, Kristine held a number of different jobs including wilderness firefighter in the Tally Lake Ranger District in Montana; soccer coach in IL, MT, & AK, including the Olympic Development Program and the Head Women’s Coach of the St. Kitt’s and Nevis National Team for over 3 years; worked as a team member on the wolf reintroduction program through the U.S. Fish & Wildlife Department in Grand Teton National Park for a winter season; spent 1 year teaching the ways of the wilderness with troubled youths in Montana to encourage a positive lifestyle (AYA), and she also was a substitute teacher and Youth Soccer coach in Alaska for 2 years.

In her free time, Kristine enjoys reading and painting, playing any sports and anything outdoors, especially soccer and golf, and backpacking, skiing, hiking, kayaking, and camping with her dogs Roux, Bug, and Zwieback, and squeaking with her guinea pig Nome. When at home, her hobbies include organic gardening, raising chickens, beekeeping, reading, and stamp collecting and scrapbooking for her daughter. In 2019 she and Brett had their first child Charlotte Elisabeth and they both can’t wait to teach her the wonders of nature and animals!! You may also meet her rescue cat Kenai when you come to the animal hospital. Giving back to the community is important to Dr. Preiser; she has recently started a therapy farm in Northern Illinois for both people and animals, pursuing her wildlife license to help any and all animals heal both physically and mentally. She volunteered as medical director of Heartland Animal Shelter from 2007 to 2018, taking pride in treating every shelter animal like her own and not just a number. Her veterinary interests include surgery, geriatric medicine, wildlife, orthopedics, exercise rehabilitation, holistic medicine, and reproduction. She is also a huge Rory McIlroy and Bayern Munich fan!! She moved back to the Midwest to be closer to her father, but her heart and passion lie in the Northwestern mountains. Someday she’ll be reunited with the wilderness, she says! 🙂 While she loves what she does in her practice, her dream job would be Dr. Oakley, Yukon Vet! If you watch that show, you’ll know why!

Client Service Representative Team Leader

Mandi's Bio

With a deep love of animals and an insatiable wanderlust, Mandi has carried her passion for critters of all shapes and sizes from coast to coast. As a teenager, her first job was at Chicago’s very own Brookfield Zoo, working as a junior docent and helping in the Children’s Zoo with animal demonstrations and teaching young children about the fantastic creatures right in their own backyards. After meeting the love of her life in the early 2000s, Mandi and her husband relocated to the small, Viking town of Poulsbo, Washington in the Pacific Northwest where she began work at a critical care and emergency veterinary hospital and fell in love with veterinary medicine. Three clinics and two baby seal rescues later, the lovebirds moved back to the Land of Lincoln, where she joined a large, private animal hospital in the north suburbs of Chicago for five years before stepping away from the field in 2020. Mandi has returned to veterinary medicine and joined Preiser Animal Hospital this summer as a lead client care coordinator and boarding director.

When she isn’t writing children’s books, dancing on quad skates, learning the fine art of tattooing, or hanging out with her two fabulous cats Luna and Pippin, you can find Mandi on the road, taking the scenic route and chasing sunsets. She loves music, photography, reading, scary movies, peach tea, drag queens, serial killer documentaries, and everything Halloween! Come in and you’ll meet Mandi right away ready to greet you with a smile!

Karen says the best part about her job is going to be getting to know all of you and your 4 legged family members and that no two days are ever the same. Please come in and meet Karen–she ALWAYS has a genuine smile on her face!


Client Service Representative

Angie's Bio

Bio coming soon!

Kenai and Miss Priscilla!

Welcome Committee
Welcome Committee Bio
We have quite a welcome committee here at Preiser Animal Hospital. Although rarely will you ever see all 3 of them in one room at one time there are 3 black cats that roam the halls of Preiser Animal Hospital. Chugach (aka Chewie) and his sister, Kenai came to Preiser Animal Hospital as strays once upon a time. Dr. Preiser took one look at their big orange eyes and fell in love instantly. Unfortunately, her German Shepherd had different aspirations for them.  And for that reason, they came to call the hospital home.  And it truly is their home. About a year later, along came a kitten named Priscilla, also a stray, and Chewie was instantly smitten. Shortly after her arrival, Priscilla injured her arm and required a little more TLC. Chewie nursed her back to health and they have been living happily ever after since. Chewie can usually be found either on the sign-in clipboard or laying in the outgoing mailbox. Kenai is the brains of the operation.  She is also our interior decorator at times, using her nails to help re-design the upholstery. As for Miss Priss. She is less enthusiastic about dogs so she tends to take cover until things quiet down.  But when no one is around you will find her stretched out on the waiting room floor with her belly waiting to be petted or begging for water at the faucet (she has us trained quite well).
