Andrew Garten

Andrew Garten, PA-C

A transplant from the East Coast thanks to the US Navy, Andrew has set down roots in the Northwest. In the Navy he worked as a journalist, editor and in public affairs. After his second enlistment and honorable discharge as a Petty Officer First Class, Andrew moved into a brief career as a Graphic Designer, which came to an end in 2008 thanks to the recession.  After hearing his friend talk about the work EMT’s do, Andrew obtained an EMT pre-test book, read it in three days and took the entrance test on the fourth day and was accepted into EMT training. During his training, Andrew discovered that he really enjoyed medicine. Even before he got hired as an EMT, Andrew had chosen to become a Physician Assistant. The next few years would prove to be the most challenging and rewarding journey of personal, academic, spiritual and professional growth. Andrew spent a month of his training in Spokane and hoped to return permanently. After training and certification were complete, Andrew was referred to Northwest Spine and Pain Medicine and is happy to have found a place to call home.

James Foster


James Foster graduated from Walden University with a Master’s degree in 2016 and has been serving and caring for patients of all ages for the past two decades.  He has training and experience in Primary Care, Internal Medicine, Rehabilitation and Geriatric Medicine. A licensed nurse for twenty years, James spent much of this time caring for elderly patients in skilled-nursing and rehabilitation homes providing interdisciplinary service and care plans for individuals with acute and chronic health conditions. James served as the clinical team lead in Primary and Behavioral Health Care Integration for three years and also served for the Salvation Army Michigan Turning Point Program as a Waivered Provider of outpatient and inpatient psychiatric services for Christian counseling. “I consider my nursing services a privilege which has polarized my professional ambition and direction toward individuals affected by chronic health disparities.” This notion is based on a non-judgemental, stigma-free, humanitarian-holistic approach which places the individual as the center-focus and empowers self-management and ownership of their care.  Two decades of nursing has made James an advocate for wellness promotion which incorporates an individual’s personal, spiritual and cultural beliefs. “Nursing has transformed me to facilitate and focus energy towards realizing and actualizing a person’s goals, optimizing their full potential and their recovery.”

Dr. Don Halcrow

Don Halcrow, DC, PA-C

Dr. Halcrow obtained a Bachelor of Science in Biology and a Doctorate in Chiropractic at the University of Western States in Portland Oregon. For many years he treated patients in Bend Oregon where he developed a strong understanding of the connection between the body’s structure and its function. Utilizing conservative therapies he helped many people; however, he wanted to offer patients even more and therefore attended the University of Washington’s Physician Assistant program here in Spokane. Naturally he chose to continue to work in orthopedics where he assisted in surgery for the next three years and helped to care for patients of all ages including top college athletes from Oregon State University. Don’s focus however remains the same, to address a patient’s concerns from a functional point of view and to help them reach their goals for improvement. Overcoming a football injury led him to his career in health care and taught him that various modalities, from conservative treatments to minimally invasive procedures, can be employed to initiate healing. His own recovery motivated him to help others achieve the same success. Don appreciates the holistic, multidisciplinary approach that Northwest Spine and Pain offers to patients. Originally from Calgary, Alberta he now calls Spokane home and appreciates the many outdoor activities here. He enjoys time with his family and friends and is an avid skier, golfer, hiker and cyclist...“My dilemma”, he says, “is which activity to do on the weekend.”


Michelle Brothers, DNP

From an early age, Michelle liked helping others with injuries and illnesses, which came in very handy growing up as a farm girl in rural north Idaho. While attending Lewis-Clark State College she worked summer jobs as a CNA in long-term care and a clinical assistant in a rehabilitation and sports training clinic. After receiving her BSN and RN license she worked as a rehabilitation hospital floor nurse in Bakersfield, CA. Michelle's experience as a nurse instilled a desire to do more for her patients. She returned to college and graduated from Loma Linda University School of Nursing with her Doctor of Nursing Practice (DNP) and passed the FNP certification soon afterwards. Being raised in a family where alternative medicine was very popular, Michelle has great respect for both “traditional” and “modern” medicine. Various personal experiences cultured her passion for helping others who experience pain on a daily basis. She loves serving on medical mission teams, including living 3 months in Uganda where one of her favorite memories was helping a young boy walk again. She is very honored and proud to be part of the multidisciplinary team at Northwest Spine and Pain Medicine.
