Delivering Patient Care for a Lifetime


At Kalispell OB/GYN, we work hard every day to help promote and protect the health, safety and quality of life for all women. All our providers are strong advocates for women’s health care. It is our mission to provide the best care for women in all stages of life through a professional and compassionate health model, a conversational approach with our patients and a supportive team consisting of our outstanding physicians, nurse practitioners and physician assistant. Assisting them is our excellent support staff of RNs, LPNs and Medical Assistants, as well as the rest of our helpful, friendly office staff.

Established in 1962 by Dr. Van Kirke Nelson and later adding Drs. Heine and Sowell, Kalispell OB/GYN has provided quality OB/GYN care longer than any other OB/GYN practice in the Flathead Valley. We’ve grown and changed with the times and the area we serve has spread outside the Flathead Valley to include many surrounding communities, such as Libby, Eureka, Cut Bank and Shelby.

Drs. Nelson, Jonas, Lavin and deHoop took stewardship of Kalispell OB/GYN and enjoy the practice of general obstetrics and gynecology, with a combined total of over 75 years of delivering babies and caring for women’s health. With continued growth of the practice, we have just added a fifth physician, Dr. Jenna Huff, so we are better able to offer our patients the best possible care.

All our physicians are board certified in Obstetrics and Gynecology, are accomplished laparoscopic surgeons, offer minimally invasive and robotic surgery, vaginal surgery and prolapse repair. They participate in teaching the University of Washington medical students during their rotations at Kalispell Regional Medical Center and help train the residents of the Family Medicine Residency Program.

Our providers enjoy caring for women who are either pregnant or hoping to become pregnant. They are strong advocates of offering women the option of having a vaginal delivery after a prior cesarean section and, along with Kalispell Regional Medical Center, offer this service to their patients. Kalispell OB/GYN is also happy to collaborate with certified nurse midwives for women who desire midwifery care. We look forward to helping women make the best health care decisions for their families and themselves.
