Dr. Willis is the first out of a long list of doctors to help me reduce my asthma symptoms. His treatment plan worked wonders for me...I highly recommend this clinic as an option if you are not seeing results through western medicine...

Can’t recommend AFM enough! Following their program and guidance helped alleviate lifelong IBS issues and hormone imbalances. ...their program and extensive lab work truly uncovered the issues of what others had said was “just stress”.

If you need to reschedule your call we ask that you contact us at least 24 hours before your scheduled time. Please call 858-264-4744 and one of our staff members will assist you in setting up another time.
Insurance generally does not cover the services that functional medicine provides, but this is what allows us to go beyond what conventional, insurance-based medicine offers, which is primarily abbreviated testing and drug-therapy only. The cutbacks from insurance companies limit the ability to provide people with the answers and solutions they are seeking when searching for an office like ours. Therefore, we do not bill insurance at this office but are happy to provide you with an itemized statement to submit to insurance on your own for potential reimbursement. Having said that, we do accept HSA and FSA, and we offer very affordable payment options or cash pay discounts for anyone who would end up needing care at this office. It is a very simple and easy process.
You do not need anything for the call, though we do recommend setting aside 5 to 10 minutes before hand to think through your story and the symptoms you would like to discuss. We find this will help you get the most benefit from the call.
Although we prefer in-office visits with our local patients, we have successfully seen patients all over the country, virtually, via zoom or phone appointments. We can typically send all test kits and requisition forms directly to the patient, as well as mail any supplies they may need throughout their care plan.
You can continue to see your primary doctor for your routine care. We are happy to communicate with your primary care provider if you would like us to, but we do not provide primary care services. We provide a whole-body approach that addresses all dysfunctions causing issues in the body. We utilize all-natural, research-based, dietary, and nutritional approaches to optimize the body, to heal from the inside out vs. merely using medications to mask symptoms. We then rerun labs so you can see all issues or symptoms have resolved. We encourage you to share the results with your primary doctor as they will be very impressed!
Providing out-of-pocket care is simple and easy. Initial visits are typically $295 and follow-up visits are $199. Please keep in mind that this may not include any diagnostics, nutritional products, or medical supplies you may need. Since each patient is unique in presentation, what you may need will be discussed and determined in an initial consultation, we will go over it in detail with you at that time. We do accept HSA, FSA, checks, credit cards, or convenient monthly payment plans as low as $99 per month. We can work with you if you need the help.
