Mike McDonald, DVM


With a vision of providing excellent veterinary care in the area, Dr. McDonald founded Bay Pines Veterinary Clinic 1977. He and his wife Joan planted a seed that has grown into a veterinary practice that employs 5 veterinarians and over 30 staff members. In 1998 they fulfilled a dream and built the new hospital to provide the best facility they could create to care for pets. Dr. McDonald graduated from Michigan State University College of Veterinary Medicine in 1975. Dr. McDonald chose Emmet County because of vast outdoor recreational opportunities. He still enjoys upland bird hunting with one of his 5 English Setters. You might also find him with fly rod in hand or on his bicycle or cross-country skis. Dr. Mac and his wife Joan have 3 grown children, Michael, Libby, and Stewart. The daily challenges of veterinary practice still excite Dr. Mac as much as they did when he was a student.

Kurt Erxleben, DVM


Even as a high school student, Dr. Kurt Erxleben was hanging around Bay Pines, volunteering in the clinic. Then came college and graduation from Michigan State’s Veterinary School and, as they say, the rest is history.

Married to Christyn, they have three children, Eden, Sara, and Noah and own multiple pets.

Tracy Dulak, DVM


Veterinary medicine is Dr. Dulak’s second career. After initially earning her Business Administration Management degree from Lake Superior State University and working in the business world for 6 years, Tracy returned to school and earned her DVM degree from Michigan State University. We are all so happy that she did! Tracy loves internal medicine, and has a special passion for treating geriatric patients. Tracy and her husband, Dominic, share their home with 2 rescue dogs, “Bean” and “Abbey” and 2 cats, “Birdie” and “Spartan.” When Dr. Dulak is not at the clinic, you can find her spending time hiking, camping, traveling, fly fishing, doing yoga, or just relaxing with her friends and family. Dr. Dulak also maintains our employee pet memorial garden at Bay Pines, which utilizes her love of perennial gardening. In the summer of 2008, Tracy became a partner with the Bay Pines Group and plans to make Bay Pines her veterinary home forever.
