    This is an update to a review I left back in January 2026. I appreciated that Dr. Willis reached…read moreout a number of times to see how they could make this right with me. Considering I still have health concerns that I'd like to correct I felt he provided a sincere concern on how to rectify the situation. As a business owner myself that was is important to me. I am willing to go along with the program designed for me (which is much different than the first time around). I cannot say if it is going to make a difference since it's only been a week. Health issues can be very complex and achieving the desired results can and usually does take many paths. I encourage anyone seeking optimal health to at least talk with AFM with their concerns and ask the honest questions and do the research on understanding your individual health concerns. Thank you Dr. Willis for responding to my previous review.

    Advanced Functional Medicine San Diego takes a truly holistic and personalized approach to health…read morethat goes far beyond traditional medicine. Instead of simply treating symptoms, they focus on understanding the root causes of what your body is experiencing. Through comprehensive and rigorous testing, you gain real insight into how your body is functioning, where your limitations may be, and what imbalances might be affecting your overall health. What impressed me most is how Sara took the time to review the results in detail and develop a clear, individualized plan designed to restore balance and bring your body back to optimal health. Their approach combines science, nutrition, and lifestyle strategies in a way that feels thoughtful, thorough, and empowering. If you're looking for a proactive and holistic path to improving your health--one that actually helps you understand your body rather than just mask symptoms--I highly recommend Advanced Functional Medicine San Diego.

    Where do I begin? Made an appointment with him on a Sunday for the Wednesday several days later,…read moreand he texted me that same day (on a Sunday!) to get more detail to best prepare for more appointment. He called when I was free, and in chatting with me he realized that it had been a rough road for me over the last couple of months and was eager to help. He suggested that I actually come into his office the next day instead(!). Fast forward to appt time, he took my lengthy history of sinus issues, persistent coughing, constant congestion, the works. You could almost see the wheels turn as he tried to put the puzzle pieces together to proactively help me with all of my symptoms that I was experience and figure out the best solution to alleviate them for me. He spent 70 minutes with me, listening, talking, allergy testing, asthma testing to get to the bottom of it. In this day and age when doctors cutting appointments short is rampant, it was so refreshing to be heard and to feel like I had an expert in my corner who wanted to help me feel better as much as I did.
