Jennifer Jamrog, DOJennifer Jamrog, DO, joined the Kalispell Regional Healthcare family in July 2017 as a physician specializing in pain management at The Montana Center for Wellness & Pain Management. She graduated from the West Virginia School of Osteopathic Medicine and completed her internship at St. Petersburg General Hospital in Florida. She completed her residency in neuromusculoskeletal medicine and osteopathic manipulative medicine in Fort Worth at the University of North Texas Health Science Center, where she was an adjunct professor in the Department of Family Medicine before moving to Montana. Dr. Jamrog believes that the body has self-healing capabilities, its structure and function are interrelated, and in order to achieve optimal health, it is important to incorporate the physical body, mind and spiritual health into a patient’s care. In addition to traditional pain management, she uses osteopathic manipulative treatment (OMT), which is hands-on care that can help the body restore normal function. She uses her hands to diagnose and treat using various modalities that can address the musculoskeletal system, lymphatic system, nervous system, cardiovascular system, respiratory system and gastrointestinal system. OMT can help many different patient populations with many different conditions. OMT can be gentle enough to treat a newborn baby or an acutely ill patient in the hospital and can also be strong enough to treat an elite athlete. OMT is often used to soften and relax various soft tissues, improve anatomical symmetry in the body, and even tone/tension and pliability within ligaments and tendons. In addition, it can improve removal of metabolic waste and supports the body’s natural healing ability. Dr. Jamrog plans to offer regenerative medicine to her patients at The Montana Center with ultrasound guided injections using prolotherapy and platelet-rich plasma.

Having lived in Colorado for six years, Dr. Jamrog appreciates all the outdoor activities that living in a mountain town has to offer. She enjoys hiking, mountain biking, skiing, snowboarding and yoga.
