Dr. David Lauter, M.D., F.A.C.S
Medical Director, Bariatric Medicine
He has practiced surgery in the Pacific Northwest since 1992. During that time his private practice has included general, vascular, surgical oncology, bariatric and minimally invasive laparoscopic and robotic surgery.
In 2012, he closed his private practice to allow time to pursue a number of other interests including overseas humanitarian surgery with Doctors Without Borders/MSF. Since then, he has worked with MSF in the Central African Republic and Democratic Republic of Congo.
“The success of bariatric weight loss ultimately depends upon a patient’s commitment to living a healthy lifestyle, which is why it is so important that every patient undergo complete evaluation as well as begin a program grounded in success from the start. This is what NorthStar has always provided and the advantage of a complete and locally based program has to offer.”

Anna was born and raised in San Francisco and is the youngest of three children. After graduating High School in San Francisco, Anna attended nursing school in Hawaii. Anna graduated with her Family Nurse Practitioner degree in 2002. She has practiced in various specialties, and discovered her passion when she found the specialty of Bariatrics.
Anna’s career has taken her across the globe where she worked for the Saudi government as a nurse. After completing her graduate degree, Anna had the opportunity to work in conjunction with the US Army to develop and manage a bariatric program in Hawaii. It was at this time that Anna discovered her passion for Bariatrics.

She finds the element to success is a true commitment to oneself, and having the support of professionals providing guidance through the process is essential. Anna believes its important to show yourself you can lose weight and that your confidence is reborn once you achieve even a five pound weight loss.
Anna has worked at Stanford University and the University of California in surgical weight management. She helped patients reach their preoperative weight loss prior to surgery, and monitored and provided guidance for patients post surgery. She also participated in research studies regarding the positive effects of weight loss. Her most recent experience is in medical weight loss.
Anna loves to travel and experience many cultures. She has found that the immersion into other cultures has broadened her horizons and given her the ability to see things from other cultural perspectives.

Sleep Medicine Staff
Zachary Webb, MD
Medical Director, Sleep Medicine
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.”

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.

Christopher P. Mathews, RT, LRCP
Christopher Mathews is President and CEO of NorthStar Medical Specialists and NorthStar Associates, PLLC. His primary interest in starting the practice was to utilize his experience and background as a Respiratory Therapist to provide care in an outpatient setting serving patients with few options to slow the progression of their disease. Having worked in acute care settings for almost 14 years, he saw patients with chronic lung disease frustrated by their disease and wanted to help them manage their symptoms, improve their quality of life and help prevent recurrent hospitalizations. By providing a safe, evidence based outpatient treatment program Christopher envisioned a way to bridge the gap in care options in Whatcom County through Pulmonary Rehabilitation and outpatient Respiratory Therapy.
Christopher’s experience and knowledge in building this program 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.
