Meet Dr. McClaren


Dr. Jonathan McClaren

Clinic Owner/Clinic Director/Chiropractic Physician

The passion that fuels Dr. McClaren as a chiropractic physician began at an early age and with a steady desire for learning and practicing health and well-being. Over the years, many chiropractors have helped him heal from injuries, improved his function, flexibility, well-being, athletic performance, and helped prevent future injuries through education and rehabilitation. Based on these experiences, Dr. McClaren naturally chose to become a chiropractor! He is thankful every day for the ways in which he helps his patients heal and improve their quality of life.

He completed his doctoral training at the University of Western States, here in Portland, Oregon. Dr. McClaren completed his undergraduate training at the University of Colorado at Boulder. He is licensed to practice as a chiropractic physician in the state of Oregon, and is credentialed by the National Board of Chiropractic Examiners.

He has obtained extensive post-doctoral training in fields relating to the focus of his practice on traumatic injuries. He is credentialed in the diagnosis and triage of the traumatically injured patient, whiplash, rehabilitation, MRI spinal interpretation, accident reconstruction, electrodiagnostics, biomechanics, and other related fields.

He is certified in Spinal Biomechanical Engineering, by the State University of New York at Buffalo, School of Medicine and Biomedical Sciences, and the Academy of Chiropractic Post Doctoral Division.

He has published articles on MRI assessment of diffuse axonal injury, and the efficacy of radiofrequency ablation for chronic facet and radicular pain.

Dr. McClaren has extensive experience in treating whiplash and other traumatic injuries, and truly enjoys working with these types of patients.

He is a volunteer builder with Habitat for Humanity, and lives with his wife in Portland, Oregon.

Chiropractors specialize in the conservative care of the neuro-muscular-skeletal system (nerves, muscles, and joints).  This includes the spine and extremities (arms, legs). Chiropractors trained at the University of Western States receive well over 1,000 hours of training in the anatomy, diagnosis, treatment, and management of extremity conditions prior to completing their doctoral training, as well as complete over 1000 hours of clinical internship prior to graduation.

Because chiropractors specialize in the conservative care of the neuro-musculo-skeletal system (nerves, muscles, and joints), chiropractic training differs from medical training. According to a comparison study of University of Western States (chiropractic) vs Oregon Health and Science University (medical):

Chiropractic students study gross anatomy for 9 months including lecture and labratory courses on gross anatomy, dissecting cadavers, over 250 hours in total. Medical students obtain about 190 hours in gross anatomy.  Chiropractic education contains 40% more study in gross anatomy.

Chiropractic students have 3582 hours of classroom training prior to graduation.  Medical students have 2465.

Chiorpractic students receive 12 more hours in neuroanatomy training.

Chiropractic students obtain 348 hours of neurophysiology, neuropathophysiology, and diagnosis and treatment of neurological & musculoskeletal disorders, including brain structure and function.  Medical students have 217 hours of neurology/neurosurgery training.

Chiropractic students have 319 hours of radiology training.  Medical students have 24.  Chiropractic training requires 13 times more radiology training than medical school.

Overall, chiropractic students receive 732 hours classroom training in anatomy/neurology, while medical students obtain 490 hours.

Do UWS chiropractic professors also teach at OHSU? Yes

Are UWS and OHSU accredited by the same higher education accrediting organization? Yes
