Dr. Maggie Wilson
Owner and Veterinarian

Maggie Wilson

Dr. Maggie Wilson (Aleff) was born and raised in Knoxville, Iowa where she first developed her love for animals.  She was active in local 4-H and is a former graduate of the Knoxville High School (Class of 2001). Following graduation, she went on to earn first her Bachelor’s Degree, and then her Doctorate in Veterinary Medicine from Iowa State University in 2009.

Dr. Wilson started her veterinary career at the Knoxville Veterinary Clinic working as an associate for Dr. Craig Burk in 2009. In 2010 she married her husband Jeff, and they moved to Western Iowa where Dr. Wilson continued to practice first mixed animal, and then small animal only medicine while further developing her skills as a practitioner.

In March of 2018, Dr. Wilson and her husband Jeff had the opportunity to move back to Knoxville and purchased the Knoxville Veterinary Clinic from her former mentor, Dr. Craig Burk.  They were overjoyed at the opportunity to return to Knoxville with their two children, Collin, and Courtney.

Professionally, Dr. Wilson has a special interest in internal medicine, dentistry, and soft tissue surgery. She is also a Fear Free Certified Practitioner who takes pride in providing her patients with positive experiences while at the vet’s office.

In her free time, Dr. Wilson enjoys spending time with her family and her pets. The Wilson’s have 2 energetic dogs Izzy and Herman, and a lovable elderly cat named Crazy.
