About AAC

At Advanced Acupuncture Centre in Livermore, California, we combine the best of traditional Oriental Medical techniques with modern Western Science. We always strive to help our patients achieve optimum health with as few treatments as necessary, not as many as possible. Using a combination of Acupuncture, Herbal Medicine, many lab tests to determine imbalances and deficiencies, dietary counseling and lifestyle recommendations, we can not only help with chronic conditions, but also improve your overall sense of well-being and happiness.

While conventional therapies focus only on an isolated, symptomatic treatment, our effort emphasizes your total health and a state of vibrant well-being. Rather than just treating the current condition, we also look for underlying causes that keep you from achieving a vibrant state of balance.

We invite you to explore our website and learn about our unique methods and philosophy. You will be pleasantly surprised to find out that achieving a state of vitality and well-being is within your reach.

Dr. Aimee Austin

Dr. Aimee Austin, DAHM, L.Ac.

True healing begins with being heard.

Welcome! I’m Dr. Aimee Austin, and I believe that your journey to wellness starts with a practitioner who truly listens.

With over 22 years of combined experience as a bodyworker and acupuncturist, I have spent more than two decades perfecting a compassionate bedside manner designed to put you completely at ease. This rich history as a practitioner gives me both the technical expertise to address complex physical issues and the genuine empathy required to support your long-term healing success.

My Approach to Mind-Body Medicine

My passion for healthcare is rooted in the powerful connection between the mind and the body. I began my journey by earning a Bachelors in Psychology, focusing heavily on somatics, biofeedback, and how our mental state impacts physical health.

To bring this knowledge into clinical practice, being a California Certified Massage Therapist and Bodyworker was my primary focus until I went on to earn a Masters in Science and Acupuncture, followed by a Doctorate in Acupuncture and Herbal Medicine. Today, as a licensed Acupuncturist in the state of California, I blend this rigorous academic training with hands-on therapeutic care to help you achieve lasting, vibrant wellness.

Areas of Clinical Focus

I am dedicated to partnering with you on your health goals, offering specialized care for:

  • Stress Management – Calming the nervous system to restore emotional and physical balance.
  • Chronic Conditions and Pain Management – Providing supportive, long-term strategies for injuries and complex health issues.
  • NAET Allergy Treatments – Eliminating sensitivities to environmental and food triggers.

Outside the Clinic

When I am not working with patients, I find my own balance by embracing the healing power of nature. You can usually find me outdoors spending quality time with my husband and daughter, or caring for our lively family of two dogs and three horses.

I look forward to meeting you and supporting you on your path to health!
