While teaching at Palmer College in the clinical sciences department Dr. Cofano had roughly fifteen student clinicians working under his license and supervision.

Dr. Cofano has published multiple peer-edited scientific journal publications on topics such as neuropathy, renal cell carcinoma, spina bifida, and Arnold Chiari malformation. While at Palmer he went on to receive advanced education in evidence-based clinical practice, permanent impairment ratings, MRI interpretation, personal injury cases, electrodiagnostic medicine, and chiropractic neurology.

With his specialized training in chiropractic neurology and electrodiagnostic medicine, Dr. Cofano specializes in treating spine pain, herniated or bulging discs, neuropathy, radiculopathy, sciatica and other neurological diseases. Dr. Cofano has years of experience in electrodiagnostic testing for neuropathy and radiculopathy and has been a former Director of Electromyography at a large multidisciplinary medical clinic in Daytona Beach, Florida. This background has made Dr. Cofano an excellent team member at Bellevue Pain Institute where he continues to uphold the highest level of professionalism and innovation when it comes to the most valuable asset, the patient.
Dr. Cofano believes that no provider should become stagnate and complacent with patient care. He also believes that treatment plans need to be individualized and personalized with constant attention to their progress and functional improvement. He is passionate about restoring function back to those who are neurologically impaired. By regularly attending seminars, educational courses and obtaining further education, he commits himself to patients improved health.

Dr. Mark Shelley, DC DACNB – Edmonds
For over 30 years, Dr. Mark Shelley has practiced chiropractic in the greater Seattle area. During his own journey of treatment for injuries, he discovered that in order to recover to the fullest degree possible, he needed the expertise of several disciplines. This realization inspired him to develop Olympic Spine & Sports Therapy, one of the first multidisciplinary injury rehabilitation clinics in the greater Puget Sound area.
Dr. Shelley grew up locally, graduating from Shoreline High School, then Shoreline Community College with honors. He then attended Sherman College of Chiropractic and graduated summa cum laude and class valedictorian in 1983. Dr. Shelley started his own practice in Edmonds, Washington, where he practiced as the senior chiropractor for 16 years. In 2000, he founded Olympic Spine & Sports Therapy.
Dr. Shelley has post-graduate training in nine different techniques including the Pettibon™ and Chiropractic Bio-Physics™ (CBP) methods. Pettibon and CBP are the foremost techniques that exist in the profession for posture correction and spinal rehabilitation. Most recently, Dr. Shelley’s continuing education has focused on new technologies of Functional Neurology and Clinical Nutrition. Presently, he is the only board certified Functional Neurologist in the Edmonds area.
Dr. Richard Leone, DC – Tacoma
Dr. Richard Leone has been serving the Tacoma area for over 50 years through chiropractic service. Educating and treating the people of Tacoma for spinal conditions has truly been his life’s work and he continues to devote his time to this endeavor.
Dr. Leone has become the foremost expert in the Tacoma area for herniated discs, bulging discs and spinal stenosis through treatment with spinal decompression and MLS Laser Therapy. He has been able to save countless patients from spinal surgery through this revolutionary treatment. After 37 years of solely treating patients with chiropractic care, he found that there was always a small percentage that did not respond to care and those were primarily disc condition patients – and they were typically the ones in the most critical and life-altering states of health. He shifted focus to an exhaustive education of the intervertebral disc along with spinal decompression and has since counseled well over 2000 patients for this specific condition.
Recently and through these consultations, peripheral neuropathy has again and again coincided with these disc conditions along with spinal stenosis. So Dr. Leone, along with Drs. Polzin and Shelley created a comprehensive protocol for peripheral neuropathy that has given hope to sufferers of this condition when they have been told countless times by their medical doctor – “you’re just going to have to live it.” The body was designed to heal itself without drugs or surgery – Dr. Leone has been saying this for 50 years and in that time, has been providing the most effective, natural, non-invasive and technologically advanced treatment for patients in the Tacoma area.
