Our Doctors

The doctors and staff of the Companion Animal Hospital welcome new clients and long time friends with their special brand of high quality, compassionate care.


Dr. Jennifer E. Kavran has been with Companion Animal Hospital since graduating from Michigan State University College of Veterinary Medicine in 2005. She lives with her husband, three cats, a cockatiel, and a budgie. She loves helping our remarkable clientele nurture and lengthen the bond they have with their animal companions. Over the past 14 years she has particularly enjoyed developing trusting relationships with longtime clients and their pets. It is rewarding to work as part of a team that is constantly striving to serve both the animals and their human caretakers to the best of their ability. In her spare time, she enjoys hiking, kayaking, snowshoeing, birdwatching, cooking and playing the harp.

Dr. Rebecca DeSimone comes to Companion Animal Hospital after practicing in Lansing for two years. She is a graduate from University of Illinois College of Veterinary Medicine, class of 2015 and moved to Michigan immediately after graduation. She grew up in a suburb of Chicago and loves calling Northern Michigan her new home. Her love for veterinary medicine is deep routed through her passion of working with people and animals. Dr. DeSimone has interests in preventative care, dentistry, and nutrition, but also the constantly evolving nature of veterinary medicine. She appreciates the long-term client relationship and loves treating your four-legged family members as her own as they continue to grow. In her free time, she enjoys hiking, bike riding and playing pickleball with her husband and spending time with their dogs Pebbles and Cooper.

What our Clients are Saying

The staff is fantastic. They were very attentive with my newly adopted fur baby, answered all of my questions and let me know the cost of treatments and meds upfront so there were no surprises at checkout. Top notch and highly recommended!

I wouldn’t take Cody anywhere else. Dr. DeSimone and your staff are extremely knowledgeable, compassionate and caring of not only my four legged babies but their Mom as well. Thank you for everything.

~ Carol R.

Oh my goodness not sure you could have done anything differently. You all were kind, accommodating, thorough, and excellent listeners. You ALL are FABULOUS!

~ Elizabeth B.

Sumo has severe cardiovascular issues that were discovered by a very thorough DeSimone and through this, led to treatment that saved his life. Beyond excellent care. Cannot recommend highly enough.

~ Ramona C.

The doctors and tech team are so kind and compassionate. They have great bedside manner and have really mastered the idea of relaxing the environment but still being direct and clear. We brought our French lop in for a sick visit after having some respiratory issues. The staff handled both her and us with such compassion and care. They even called a few days later to ensure we weren’t having issues administering her medications and to check in. They will exclusively be our vet going forward!
