I tell people that Gerald is a wizard. Right after the first consultation, he found things that specialists at Standard, UCSF, Palo Alto Medical Foundation missed. My migraines are gone and my digestion is finally fixed. I feel amazing!

Vickie P.

After starting my nutrition program, my menstrual and back cramps are much less intense and for a shorter duration of time. The nutrition & herbs also helped with my sinus allergies and headaches that have plagued me for years. They’re now greatly reduced!

Jamie K.

I developed muscle spasms and eye twitching after a medical procedure at a hospital. The doctors there wanted me to take more drugs. I decided on a different route and found my home for wellness. No more muscle spasms. No more eye twitching. I highly recommend!

Makaela M.

The practitioners were able to explain to me in detail what’s going on with my body and how my diet has caused a large part of my health issues. My fatigue and lack of energy was due to many chemicals from work, building up within my body. I highly recommend this place!!! The staff is very friendly. These people are awesome!

Robert D.

I had the worst digestion ever. Had to use a bathroom without notice at random times during the day. Upon the initial consult, I knew which foods were causing the issue and my digestion has been flawless ever since. My belly has also shrunk too! Great people. Great place.

Bill H.

I had hives for months and cystic acne that got worse with menstruation. Hormone imbalances and skin issues have plagued me for years. I started a program to eliminate chemical and heavy metal toxicities and now my skin is clear, my digestion is flawless and my hormones are balanced.
