Welcome to Anderson Medical Specialty Associates

Welcome to Anderson Medical Specialty Associates. Dr. Paul Anderson and the physicians at AMSA offer innovative medical solutions and compassionate care for patients with a wide range of critical and chronic health concerns. Our practice areas include:

  • Assessment & Customized Care of difficult-to-treat conditions
  • Integrative Oncology
  • Intravenous Infusion Therapies
  • Hyperbaric Oxygen Therapy
  • Genomic Medicine

We are located in the North Seattle area with easy-to-reach offices in Northway Square East, just off of I-5. We are open Monday-Friday, by appointment only.

AMSA participates in many major insurance plans. Coverage may vary on different plans for the types of procedures and therapies we offer. Our experienced, caring staff can help you learn what services may be covered for you during your treatment at AMSA.


Our specialized treatment approach exists at the unique intersection of time-tested natural medicine and the most current technical research into the body’s immune and genetic health. To monitor the efficacy of our protocols and coordinate the complex care that many of our patients require, we offer our prescription-grade Intravenous and Hyperbaric Oxygen therapies and many lab services right in our AMSA office. All clinical medicine is administered by our highly trained and accredited physicians, nurses, and physician assistants, using state-of-the-art equipment and pure, safe, custom-compounded IV nutrients and pharmaceuticals.

Extending our scope of service, we now offer general women’s and men’s health visits as well as adjunctive pediatric care. And because we consider supportive care a valuable part of the healing process, many of our physicians are also trained in disciplines such as acupuncture, massage, cranial-sacral therapy, trigger point injections, and spinal manipulation.

We maintain an on-site dispensary stocked with many of the nutrient supplements that our physicians recommend. And our office team is always available to call in prescriptions or order specific supplements for you.


A Healing Environment in our Private Medical Facility


Our office is designed to help you and your family members relax during your doctor visits and treatments. Two large IV rooms feature comfortable recliners and respectful semi-private spaces for each patient. Our Hyperbaric Oxygen and Infrared Sauna chambers are housed in dedicated Physical Medicine treatment rooms. Every AMSA physician and nurse makes your comfort their top concern. They will check on you regularly during your treatments, with consideration and skilled attention.

Due to the environmental and chemical sensitivities in our patient population, AMSA is a fragrance-free office. We ask that you refrain from wearing perfumes or essential oils when you visit us.

Intravenous Therapy


Intravenous (IV) Therapy is a medical procedure that delivers micronutrients and pharmaceuticals directly into the patient’s bloodstream.

Hyperbaric Oxygen Therapy


Hyperbaric Oxygen Therapy (HBOT) is an intermittent, high-dose oxygen treatment administered within a special chamber.

Integrative Oncology


Integrative Oncology is the medical specialty devoted to improving quality of life and clinical outcomes in those with cancer.

Genomic Medicine


Genomics (or genomic medicine) is the use of your genetic signature or genome for more personalized medicine.
