Patrice was excellent in my care. She was friendly yet very professional. I didn’t even feel the needle stick when preparing to take my blood samples!

Excellent Customer Service!! I just completed my second year as a member of FunctionHealth and I can tell you that it's the only service I use. If I were to go to a doctors office and request the same tests....thousands of dollars. The value is unbeatable.

Thank you for the kind words, Michelle. We’re glad Function is helping make your results easier to understand and giving you deeper insight into your health. We appreciate you sharing!
I liked everything about the service except one aspect: I do not like there is no choice to not sign up for automatic renewal. One should be given a choice rather than having to go on the site and cancel prior to renewal.

honestly- the ai cx platform is so frustrating. It took me weeks to rebook an appointment that was misbooked by the team and it was just super disappointing.
