S. Craig Humphreys, MD
Fellowship-Trained Spine Surgeon

Dr. Craig Humphreys grew up in Alaska, with his family entrenched in the local community in Anchorage. His dad, Richard Gene Humphreys, first arrived in Alaska in 1955 working on the early warning defense system for the United States under an air force contract with International Telephone & Telegraph. Craig’s mother, Carolyn Humphreys, started elementary school teaching in Anchorage in 1970 at Northern Lights, Tudor, Scenic Park and Denali elementary schools, and ultimately retiring from teaching in Alaska after 25 years in 1995. Dr. Humphreys attended Sand Lake/Gladys Wood Elementary School in Anchorage, and then Dimond/Mears Middle School and High School, graduating in 1981.

During the summers, to save money for college, Craig got exposed to all of Alaska, doing heavy labor working long hours on the North Slope with oil companies. The long workdays in the summer enabled him to save enough money to attend The University of Notre Dame where he earned his undergraduate degree in biology.

After graduating from the University of Notre Dame, he attended Loyola Stritch School of Medicine where he received his medical degree.
He then completed an Internship and Residency at Loyola University Medical Center while also volunteering time as an MD in other countries, including India, St. Lucia and Lithuania.
Dr. Humphreys then completed a Fellowship in Orthopedic Spine Surgery at The Medical College of Wisconsin in Milwaukee.

In 1996, he joined the Center for Sports Medicine and Orthopaedics in Chattanooga, Tennessee, where he practiced for more than 15 years with a spine specialized practice attracting complex spine patients from across Tennessee and northern Georgia.

Through a long career as a spine surgeon, Dr. Humphreys was also involved in spinal research and has contributed to more than 70 publications. He has designed spinal implants and is currently working on a Total Lumbar Joint Replacement that maintains motion in the spine and instrumentation related to minimally invasive spine surgery.
In 2010, after a very successful career as a spine surgeon in the South, the Humphreys family began exploring a relocation back to Alaska to enable Dr. Humphreys to finish his spine surgery career where he grew up in the Kenai Peninsula.

Dr. Humphreys’ practice philosophy is to explore and exhaust all non-surgical options in advance of the patient considering spine surgery. This includes the use of spine-specialized therapy and injections that can relieve pain symptoms. Dr. Humphreys is at Kenai Spine, located at 240 Hospital Place, Suite 103 in Soldonta. You can contact him at (907) 260-5455.
