Kevin B. Windsor, DVM
Practice Owner

Dr. Windsor earned a BS in biomedical science, with honors, from Texas A&M University in 1992. He then obtained a degree from Michigan State University College of Veterinary Medicine in 1997. In 1998, he completed a rotating internship in small animal medicine and surgery at Washington State University, where he specialized in soft tissue and orthopedic surgery. He then returned to Michigan, where he served as a relief veterinarian, specializing in emergency and general medicine, at various Metro Detroit area veterinary hospitals. In 2000, he joined Beverly Hills Veterinary Associates, Inc., and in 2013 Dr. Windsor purchased the hospital and became Practice Manager.

Dr. Windsor’s special interests include ophthalmology, surgery, dermatology, and internal medicine, including ultrasound and endoscopy. He attends more than 50 hours of continuing education per year. He is a member of the American Veterinary Medical Association, Michigan Veterinary Medical Association, Southeastern Michigan Veterinary Medical Association where he is past president, Veterinary Orthopedic Society, and American Animal Hospital Association. He passes his free time with running, swimming, golf, photography, and cooking. He lives with his wife, Sondra; his daughter, Mallory; son, Matthew; and two dogs—a Heinz 57 named Magglio Ordonez and a knuckle-headed golden retriever named Sully Sullenberger.

“I have been fortunate to call Beverly Hills Veterinary Associates my home for the bulk of my veterinary career. Our practice has grown as a result of referrals from friends and families like you. This is a testament to the passionate and hardworking team we have assembled. We know that it takes many people with years of training, experience, and dedication to achieve this high level care. We take your pets’ health very seriously and are proud that you have chosen to entrust them to our care. We want to extend to you our deepest thanks for choosing Beverly Hills Veterinary Associates.”

Jen Brown, DVM

After growing up in Troy, Michigan, Jen Brown attended Lake Superior State University, obtaining a bachelor’s degree in biology and chemistry in 1993. At Oklahoma State University, she received honors in soft tissue surgery, graduating with a Doctorate of Veterinary Medicine in 1997. In Dallas, Texas, she worked as a mixed animal practitioner (equine, exotics, and zoo animal medicine and surgery) at a general practice, interned at Animal Emergency Hospital in Dallas, and was part of veterinary teams at Dallas World Aquarium, Dallas Zoo, Oklahoma City Zoo, and Arbuckle Wilderness, where she worked with large cats (lions, tigers, cougars, and wildcats).

Dr. Brown returned to Michigan in 2001, working for various clinics in St. Clair Shores, Shelby Township, Lake Orion, and Clarkston. Working as a relief veterinarian allowed her the flexibility to spend time with her two sons, Emerson and Peyton, and her English setter, Buck, while working at emergency clinics in Flint and Clinton Township.

She has been a member of the AVMA, AAZWV, and AAFP while obtaining 50 hours of continuing education per year. Professional interests include cardiology, soft tissue surgery, emergency medicine (trauma) and critical care, and reptile and avian medicine, as well as senior care with emphasis on pain control.

When not at work, Dr. Brown can be found on the ice playing hockey. Being an avid Red Wings fan is only the beginning of her hockey obsession—this year, she plays for Senior Women’s Honeybaked AAA team.

“Beverly Hills Veterinary Associates has been the perfect place to allow me to emphasize the role owners have in the care of their pets. The talented technicians, animal care assistants, receptionists, and veterinarians at Beverly Hills Veterinary Associates, along with great clients, energize me every day. Knowing we are a team that includes owners in the preventive care measures for their pets, and can offer high-quality medical and surgical care, makes this hospital special.”
