I am so very pleased with this clinic and the doctor I saw for primary care! I have multiple chronic illnesses and most doctors tell me they can’t or don’t know how to treat me due to my complex issues, but they were so kind and reassured me that they will get to the bottom of all of my health problems. I was looked at as a whole person and wasn’t just thrown medications to mask my symptoms. I’m happy to have found this practice and I’m excited to keep coming back!

Initially, I contacted Lam Clinic because I was having symptoms that I could not fit into the informative newsletters from Lam Clinic and I was scared. My father died of end stage kidney disease that resulted from diabetes. This hasn't been easy watching the same things happen in me. My PCP fights me at every corner because I want to be well and that causes me not to fit into the standard model for diabetes treatment! Dr. Carrie has been so patient with me. She has helped me to understand what my body is saying to me through my fear, anxiety and shame. I understand so much more about myself and can take personal responsibility for the choices I make with food and with the medical professionals in my life. I also need to say that EVERYONE with Lam Clinic have been pleasant to work with - from insurance, billing, and technical questions! If you want to get well, Lam Clinic is a tremendous resource!

Thank you Dr Carrie for your continual help with my GI issues and allergies, that is related to my Harshimoto condition. The lab test through your interpretation helped me to better understand my condition. I have not experienced a flare up for quite sometime now. I am grateful for your help.

Dr. Carrie Lam is kind and knowledgable; she worked through many difficult issues and gave me a plan of action. Prior to me becoming her patient, I worked with Adrenal coaching with Dr. Michael Lam, Mrs. Dorine Lam and staff. They helped me recover from complete exhaustion in 2019 , and when i could not find a doctor locally for my dizziness/sinus/ ear infection , they recommended Dr. Carrie; she and her staff came to the rescue. Thank you all!

What is Integrative Functional Medicine?

Functional medicine is a very specific area that focuses on a few key things: finding the underlying cause of a patient’s health problems, using a laboratory based analysis system to determine what is wrong, using supplements to correct problems with medications as needed, and focusing ever more and more on lifestyle changes such as diet, exercise, sleep and meditation.
