Krystel Elliott-Theberge is a family medicine physician with a strong passion for women’s health and prenatal care. She’s dedicated to supporting patients through every stage of life.

Amy is our empathetic, patient, and reliable medical assistant. She thrives on the variety that primary care offers, whether she’s recording vital signs, performing phlebotomy, irrigating ears, assisting with procedures, or managing behind-the-scenes tasks like coordinating referrals, communicating with patients, and maintaining equipment. Having worked with children her entire life, Amy has a natural affinity for our pediatric patients and brings a calm, reassuring presence to every interaction. Outside of the office, she enjoys exploring the outdoors, practicing yoga, spending time with her nieces, and volunteering at a local horse rescue.

Kristin Forbush is co-owner and office manager of the Osteopathic Center for Family Medicine. Alongside her husband, Dr. Jack Forbush, she helps lead a practice built on the belief that medicine should be personal again. Kristin oversees the operations, billing, and administrative infrastructure that allow OCFM's physicians to focus on what matters most — being fully present with their patients. Her care for the practice runs deep, and patients often experience that directly in the thoughtful, unhurried way OCFM is run.
