TAI Longevity & Aesthetics is a private, nurse practitioner–led practice in Phoenix and Goodyear, Arizona, founded by Teresa Le, MSN, FNP-C. Specializing in regenerative medicine and aesthetic longevity, TAI goes beyond standard lab ranges to uncover cellular and hormonal imbalances traditional medicine misses. Every protocol is built on a foundation of 90+ biomarkers, a 75-minute first consultation, and four integrated pillars: Biological Diagnostics, Regenerative Medicine, Hormone & Peptide Therapy, and Aesthetic Medicine. From mesenchymal stem cells and exosomes to bioidentical hormones, peptides, and medical aesthetics, every treatment is designed and performed personally by Teresa — nothing generic, nothing rushed, nothing hidden.
