Healing Patients Throughout Maple Valley, WA and the Surrounding Area

Diseases and illnesses are named and categorized by measurable symptoms. Most people believe that when symptoms are subdued, they’re “cured” or “healthy” again without the cause of the symptom being discovered. Richard W. Koss D.O. PLLC  goes above and beyond traditional medicine to address your medical condition.

Founded over 140 years ago, Osteopathy is a philosophy of life that uses anatomical and scientific principles to treat the entire person, not just the spine. One of the main principles is that the body has an inherent ability for self-healing that comes from within the patient. An Osteopathic physician’s job is to remove any hindrances or blockages to health. If all systems are functioning at peak efficiency then chances of getting sick or staying sick are extremely low.

Richard Koss was awarded a BS in Physical Education Summa Cum Laude from Springfield College in Springfield, Massachusetts in 1976. He continued a Fellowship and Teaching Assistant position in Anatomy & Physiology for 2 years at Springfield. Dr. Koss received his D.O. degree at AT Still University College of Osteopathic Medicine in Kirksville, Missouri in 1982 and subsequently performed a rotating internship at Normandy Osteopathic Hospital in St. Louis, Missouri. He joined the US Air Force in 1983 and served in Family Practice as a Flight Surgeon, Chief of Air Transport, Chief of Emergency Services, and Chief of Family Practice. He returned to Kirksville in 1987 to pursue a residency in Osteopathic Manipulative Medicine. He joined the faculty at AT Still University in 1990 as Osteopathic Principles and Practice Assistant Professor. He then joined the faculty in the Osteopathic Manipulative Medicine Department at the University of North Texas Health Sciences Center in Fort Worth, Texas as Department Vice Chair. He has passed Specialty Board Exams for both the ACOFP in Family Practice and also the Osteopathic Manipulative Medicine exam, and is double Board Certified. Since 1999, Dr. Koss has been in private practice, specializing in Osteopathic Manipulation.
He presented a paper on the Bioelectric Properties of Fascia at the 1990 AAO Convocation in Cincinnati, Ohio. He was deemed Educator of the Year in 1997 at the University of North Texas. He was named one of “Seattle’s Best Doctors” in the 2002 issue of Seattle Magazine.

In his years of experience, Dr. Koss has seen amazing results achieved from his treatments but understands that Osteopathy isn’t the answer for everyone. He works closely with other medical professionals in the area and is more than happy to discuss and refer patients to alternative practices.

The first step to Osteopathy is the careful examination of the patient with the hands, along with any other standard medical examinations. Once the causes of ill health, and or disease have been identified, and the areas of restrictions located, then careful manipulation of the region will help the body recover and restore a healthier situation.


An initial Osteopathic treatment usually lasts about 90 minutes and includes a full history and review of all the systems and conditions, a physical exam, and an Osteopathic structural exam. Dr. Koss will typically offer some very specific, yet simple exercises to do. These exercises are more important than the treatment because they are designed to keep the treatment process going for as long as possible.

Follow-up visits are typically every two to three weeks and last about 45 to 60 minutes. They are timed to be when the benefits of the treatment and exercises slows or ends. As things improve the treatments will be scheduled farther apart hopefully to a time where you no longer need treatments.
