JEFF WIEMANN
Dr. Wiemann's Bio
Dr. Wiemann started out doing scientific research but was not fulfilled. The research world was just too far from everyday things in life that mattered to him. He states that “practicing medicine is very real and definitely what I should be doing with my life. I strive to become a better veterinarian and person every day. I really like cats, but dogs are my favorite animal by far. I am fascinated by the fact that humans and dogs have been living and working together for over 100,000 years. The bond between dogs and people is unlike that between us and any other animal. I can’t imagine living without dogs.”

Shanae
Shanae 's Bio
Growing up in southern Minnesota, Shanae had always loved and wished to work with animals. It wasn’t until 2019 that she was finally able to pursue her passion and started working at a shelter, where she absorbed the knowledge of shelter medicine before transitioning to general practice. Life has bounced her around a bit, but she has settled in nicely with the Andover Animal Hospital crew. Her favorite part of working in Vet Med is earning the trust of the more anxious and unsettled pets.
When she’s not loving on clients’ furbabies, she can usually be found drinking a vanilla white mocha, reading, traveling, spending time with friends and family, or getting easily distracted by any dog she sees. She’s a dazzling Dog Mom who embraces her quirks and just can’t sit still when there’s music playing.
