Dr. Burden is also board certified in Bariatric Medicine.

In 2000 Dr. Burden entered the field of Bariatric Medicine, joined the American Society of Bariatric Physicians and founded Northwest Medical Weight Management, a clinic devoted to medical weight management and the health problems associated with obesity. After a number of years of successful clinical practice, Dr. Burden joined NorthStar Medical Specialists.

Dr. Zachary Webb is medical director of sleep medicine at Northstar Medical Specialists and focuses his practice entirely on the management of sleep disorders. He is board certified in neurology and Sleep Medicine. In 2005 he completed his neurology residency and fellowship training and moved to the Bellingham area.

Dr. Webb has an interest in all aspects of sleep medicine. He considers good communication to be vital to diagnosing and treating his patients. “Most sleep problems are treatable. Helping patients understand the cause of their sleep disorder is instrumental in successfully treating the problem.”

Dr. Webb’s wife is also a physician, who practices pediatrics in Mount Vernon. They moved to this area one year ago because of proximity to the Cascade Mountains and the Pacific Ocean, as well as having family nearby in Seattle. Both he and his wife grew up in the Pacific Northwest and had always hoped to set up their practices in this region. In his free time, Dr. Webb can be found biking, hiking, spending time with his wife, woodworking, and gardening.

He directed the St. Joseph’s and St. Luke’s Hospital Pulmonary Rehabilitation programs before their discontinuation in 1988. His extensive background in Pulmonary Rehabilitation from the University of California, San Diego’s renowned training and research center, make his expertise uniquely valuable.

He has been part of the clinical and administrative staff since the very early stages of the practice as a licensed Respiratory Therapist with over 13 years of acute care experience prior to joining NorthStar in 2001.

Christopher’s expertise in Pulmonary Rehabilitation and Respiratory Therapy were only further advanced by his ongoing professional interests in Sleep and Bariatric Medicine. Bringing these three medical disciplines together in a complimentary, accessible environment has been the long term vision of the practice.

Christopher’s true happiness though, is found at home in Bellingham with his wife Carolina and two children, Thomas and Sophia.
