The  Asthma and Allergy Center of Whatcom County  is a medical specialty office serving residents of Whatcom and surrounding counties for over thirteen years. Dr. Anderson has over twenty years experience in evaluating and treating children and adults with allergic and immunologic disorders. The full spectrum of services that fall within the expertise of the board certified Allergist-Immunologist are provided at the Asthma and Allergy Center. Our mission, as stated on the home page is to improve the quality of life of children and adults through the art and science of asthma and allergy care.

A large part of our work is in consultative services, assisting and working with primary care and other medical  providers in diagnosis and development of treatment plans for their patients.

We are contracted with, or accept most insurance plans active in Whatcom and surrounding counties. A brief call to the office is all that is needed if there are any questions about which plans that we work with. To ensure  that services will be covered by a specific plan, we will ask about the insurance provider when appointments are made. Any questions regarding the details of  insurance coverage can be answered by, or investigated by the front office personnel. Many plans include a co-pay  which is the patient's responsibility.  We request that this component of reimbursement be provided at the time of the visit. For those without insurance, we will request fifty percent of the payment for services at the time of the visit, and a payment plan arranged for the remainder if necessary.

Many insurance providers operate through  managed care plans that require a referral from the primary care provider before a patient can be seen.  It is a good idea to learn about insurance plans and special requirements before changing plans or after switching. A new plan could require a referral before being seen by a specialist when an established, familiar plan did not. A referral, if required, will need to be received by the Asthma and Allergy Center before services are provided. We will work closely with patients and primary care providers to help ensure that referrals are in place in a timely fashion. When referrals are required, it is important for patients  to understand the requirements of their specific plan. 




The Asthma and Allergy Center of Whatcom County is located in the Barkley District in Bellingham, just off of Woburn Street on Barkley Boulevard, across the street from the movie theater. The office is on the second floor of the Barkley Medical Center which is near Wells Fargo Bank located on the corner of Woburn and Barkley Blvd., across the street from Barkley Village.  We are not in the Barkley Village area of shops and restaurants.

Dr. William Anderson is board certified in the specialty of Allergy-Immunology. He earned this specialty designation in 1993 after acquiring the necessary knowledge and experience, and passing the board exam in pediatric and adult Allergy - Immunology.  He graduated from the Allergy - Immunology fellowship program at the University of California at San Diego, spending an additional 3rd year there, completing research projects and scientific articles, and gaining additional experience in pediatric allergy and immunology at  Children's Hospital and Health Center.  He also participated in the the NIH sponsored Nasal Dysfunction Clinic during his last year, learning valuable information about sinus disease and dysfunction of the sense of smell and taste. In addition to direct care of children and adults during his specialty training, Dr. Anderson was actively involved in both basic and clinical research. Prior to his training in allergy - immunology,  Dr. Anderson earned  board certification in Internal Medicine at the George Washington Hospital in Washington D.C.

Since his undergraduate studies at Oregon State University in the Department of Microbiology where he first became interested in the field of immunology,  Dr. Anderson has been active in medical research, pursuing an understanding of the basic mechanisms of disease. During medical school at the Oregon Health Sciences University in Portland Oregon, he contributed to research involving bacterial infections important in human disease. During his fellowship training in Allergy - Immunology,  he was actively involved in research in the basic disease process of allergic reactions and allergic inflammation important in nasal allergy and asthma. He also participated in clinical  research of new medications for the treatment of asthma.

Since entering private practice in 1994, Dr. Anderson has devoted his time to medical practice and the direct care of children and adults suffering from allergic and immunologic disorders. He has replaced his basic research in the field  with the pursuit of the latest published information on both the diagnosis and treatment of allergy, asthma and immunologic diseases, and on the basic mechanisms of allergic reactions and allergic inflammation.

With a strong  background in research, an understanding of the basic disease process in allergic and immunologic diseases, over twenty years of experience in diagnosing and treating children and adults with allergic and immunologic disorders and knowledge of the latest advances in the field,  Dr. Anderson is uniquely qualified to provide efficient, optimum patient evaluations, education and treatment options for children and adults suffering from asthma, allergy or  immune dysfunction.
