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!

Linda R.
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.

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.
Response from Function HealthJul 29, 2026
Thank you for taking the time to share your experience. We’re thrilled to hear you enjoyed Function overall. We appreciate your feedback about automatic renewal and will share it with our team.

Sofie
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.
Response from Function HealthJul 28, 2026
Thank you for taking the time to share your feedback, Sofie. We’re sorry the rescheduling process was so frustrating and took longer than it should have. This isn’t the experience we aim to provide. We’re glad our team was able to help get your appointment booked, and we appreciate your patience throughout the process.
