Shane G. Machen, D.O.

Who would ever have believed that a bull riding, potato farming fisherman from Idaho would become a successful bi-lingual Doctor of Osteopathic Medicine and establish a practice in Idaho Falls, fast becoming a favorite with his patients, young and old? It’s true. Dr. Shane G. Machen, D.O. is simply a boy from Roberts who has taken a desire to serve, backed it with a quality education, moved to Idaho Falls, and created a compassionate and successful family practice that, as a Doctor of Osteopathy, goes well beyond that of an M.D. He has an exemplary bedside manner, putting the need of his patients first and foremost, and continuously strives to provide them with the best available quality of care by keeping abreast of the rapidly evolving advancements in medicine.

As a young man, he found that feeding cattle in -20° weather, training horses, wrestling, bull-riding, fighting wildfires for the BLM, and taking two years off to serve a mission in Chile has provided him with a respect for hard work and dedication. This also created a desire to share his talents and abilities, as he did in 2008 when he participated in a traveling doctor’s program in Guatemala.

Dr. Machen received his Associate of Science at Brigham Young University; his Bachelor of Science at Idaho State University; his Doctor of Osteopathic Medicine at Kansas City University of Medicine and Biosciences in Kansas City, Missouri; and trained in Family Medicine at the Research Medical Center in Kansas City, Missouri as well.

Dr. Machen was drawn to establishing a family clinic because of one important lesson he learned during his residency…Family medicine doctors were some of the happiest physicians he knew on rotations. And, above all, he wants to be happy, become an integral part of the community, and make a difference in the lives he touches.

He takes pride in being able to provide urgent care for his patients, thus saving them sometimes hundreds of dollars over a trip to an emergency room. He’s also great with kids and considers his pediatric services to be one of the most rewarding aspects of his practice. With his training in internal medicine he can effectively diagnose and treat a variety of illnesses, diseases, and infections. Musculoskeletal issues such as pinched nerves, spinal misalignment, and carpal tunnel, as well as neurological issues can also be effectively addressed through the scope of the Osteopathic family physician.

Dr. Machen is a family man. He met his wife, Esther, at Rick's College (BYU-Idaho), and they have been married for over 15 years. They now have four beautiful children, two boys (Stetson and Austin) and two girls (Cheyenne and Bonnie). Esther also practices medicine in Idaho Falls at her own dental practice. 

So now you know a little more about this Idaho boy. And the icing on the cake is he’s personable, he’s dedicated, and a caring family physician.
