Premier Functional Medicine
Institutional Profile
Premier Functional Medicine is a Phoenix, Arizona cash-pay practice co-founded and run by Andrea Jullette-Fantigrassi, DNP, ACNP-BC, and Michelle McGee, AG-ACNP. The practice holds a 5-star rating across 23 Google reviews and operates across functional medicine, hormone therapy, peptide protocols, regenerative medicine, and a dedicated aesthetics program. Peptide therapy is a core specialty, with the catalog including BPC-157, TB-500, Sermorelin, Tesamorelin, Semax, GHK-Cu, and Thymosin Alpha-1 — a depth that spans tissue repair, growth hormone optimization, and immune support. Hormone therapy is equally developed, offering bioidentical hormone pellets, estrogen transdermal formulations, and related delivery options. Reviewers mention Michelle McGee specifically for fat loss guidance, and reviewers describe seeing Andrea Jullette-Fantigrassi for IV hydration after exertion — citing same-day availability and personalized care. The aesthetics program is a notable Tier 3 flag, running dedicated service pages for BeautiFill laser liposuction, Dysport, chemical peels, Procell microchanneling, PRP facials, CO2 laser, fillers, and Brazilian Butt Lift, and the practice hosts aesthetics parties. No insurance is accepted — the regenerative medicine FAQ explicitly states most therapies are not covered, making this a fully cash-pay operation. Credentials from two board-certified nurse practitioners anchor the clinical credibility.

Notable Reviews
“She prescribed Semaglutide for my weight loss and I have slowly but consistently lost 27 lbs. She is patient, understanding and encouraging. I still have a way to go to meet the goal we have established.”
“Andrea and Michelle treated my tennis elbow that I had been struggling with for six months and it was gone after two treatments!! Had an ortho doc do injections and none of it worked until I went to Premier.”
“After coming back from a long day of hiking, I was tired and dehydrated. A quick stop at Premier Functional Medicine for an IV, and I was feeling great.”
“Michelle went above and beyond to provide me with expert after-hours assistance that was both comforting and effective after injuring myself at the gym.”
“Michelle McGee AG-ACNP & Andrea Jullette-Fantigrassi DNP are the best! They offer so many services in office. They have helped me and a group of friends and I would refer them to anyone!”
