Phoenix & Goodyear, Arizona · Nurse Practitioner–Led Care

Longevity is the new luxury.

TAI is a private practice in regenerative medicine and aesthetic longevity. We look beyond "normal" lab ranges to identify the cellular and hormonal imbalances traditional medicine misses—and design precision protocols for profound vitality.

— The Philosophy

We do not
chase youth.
We restore
the system.

Longevity is not a product. It is a practice—a long, patient correspondence between biology and attention. At TAI, we begin where most clinics end: with a full map of the body's signals.

From there, we design a protocol that is unmistakably yours—regenerative, endocrine, aesthetic, measured. Nothing generic. Nothing rushed. Nothing hidden.

TAI Longevity & Aesthetics is a private, nurse practitioner–led practice with offices between Uptown Phoenix and the Biltmore and in Goodyear. We offer regenerative therapies including mesenchymal stem cells, exosomes, and PRP/PRF; peptide and bioidentical hormone protocols; medical aesthetics and injectables; functional medicine, NAD⁺ and IV therapy; and comprehensive biomarker diagnostics — for patients across Phoenix, Goodyear, Scottsdale, Paradise Valley, Arcadia, and the West Valley — with virtual care for patients in Arizona, Washington, Oregon, and Florida. Every protocol is designed and performed by Teresa Le, MSN, FNP-C.

what makes this practice different

Why patients drive past
a dozen clinics to get here.

01

One practitioner, start to finish

You will not meet a different injector every visit, or explain your history twice. Teresa designs your protocol and performs your treatments — which means the person holding the syringe is the same person who read your labs.

MSN, FNP-C1:1 ProtocolsNo Rotating Injectors
02

We test 90+ markers before we treat anything

Standard panels were built to catch disease, not to find the drift that makes you feel unlike yourself. We map metabolic, cardiovascular, hormonal, inflammatory, and nutrient status first — then write the protocol the data actually supports.

MetabolicCardiovascularHormonalInflammatoryNutrient
03

Regenerative first, prescription second

Where the biology allows it, we reach for the body's own repair machinery before we reach for something that only manages the symptom. Stem cells, exosomes, PRP/PRF, and peptides are the practice's spine — not an add-on menu.

Stem CellsExosomesPRP/PRFPeptides
04

Aesthetics that rebuild tissue, not just fill it

The same regenerative logic runs through the cosmetic work. Exosomes, PRP/PRF, and biostimulators are used to support the skin's own collagen and structure — so what changes is the quality of the tissue underneath, not only its volume. Injectables are placed with a restrained hand, toward the face you recognise in old photographs rather than a different one. Patients tend to describe the result less as looking altered and more as feeling like themselves again.

Seventy-five minutes, and no package upsells

Your first consultation is long because the conversation is the diagnostic. From there it is monthly follow-up and re-tested biomarkers — we change what needs changing and hold what's working. Nothing is sold to you in a bundle.

The Name
a letter from the founder
Teresa Le, MSN, FNP-C — founder of TAI Longevity & Aesthetics
Tai.
/taɪ/ — named for my son, Tayden Tai.

In Vietnamese culture, Tài represents talent and fortune—two qualities that, when held together, create abundance.

I believe every person is deserving of a life abundant in good health, love, and peace. That belief is the foundation of every protocol we write, every conversation we have, every door we hold open for someone who has been told their symptoms are "just part of aging."

TAI is more than my son's name. It's the promise I make to every patient who walks through our door.

the patient experience

A quiet practice.
Designed around you.

i. Intake

A full biological map

Seventy-five-minute consultation. Comprehensive lab panel covering over 90 markers. A conversation about what you actually want to feel like—not what a 15-minute visit allows.

ii. Design

A protocol, written for you

Your nurse practitioner designs a layered protocol across regenerative, endocrine, and aesthetic pillars. Every decision explained. No package upsells, ever.

iii. Continuum

Care that follows the data

Monthly follow-ups, re-tested biomarkers, and protocol refinement. We change what needs changing. We hold what's working.

The people
we get to know.

★★★★★ Five-star reviews on Google
★★★★★
After years of seeing multiple doctors, spending an incredible amount of money, and still feeling dismissed and unwell, Teresa was the one who finally connected the dots. She helped me uncover and properly address my thyroid dysfunction, gut issues, and underlying malnutrition—and for the first time, I felt heard, taken seriously, and guided with a clear, thoughtful plan. One of the best health decisions I've ever made.
— Angela D.
★★★★★
After my pregnancy, I struggled to lose weight and didn't feel like myself. With Teresa's guidance on peptide treatments over the past few months, my results have been truly life-changing. She is professional, knowledgeable, and incredibly compassionate—I felt supported and confident every step of the way.
— Faith
★★★★★
I found Teresa by chance on a trip to Arizona. Now I fly 2,308 miles a few times a year for her services. She does incredible work, has shockingly great prices, and a personality to match it all. On a scale from 1 to 10, I'd give her a 17.
— Lisa E.
★★★★★
I've been receiving peptide therapy from Teresa and I feel great. Not only are her products high quality—she's very knowledgeable and makes sure to explain everything thoroughly. Highly recommend her for anyone exploring peptides. I've never felt better.

Chapter 06
before you book

Questions we're
asked most often.

A physical is built to rule out disease. If nothing is broken, you're sent home. Longevity medicine asks a different question: where has your biology drifted from its own optimum, and what would it take to bring it back? That means testing more markers, reading them against optimal ranges rather than population averages, and treating the drift while it's still reversible.

No. Patients come to us from both directions — some have been dismissed for years with fatigue, brain fog, joint pain, or weight that won't move, and some feel fine and want to stay that way. Both are legitimate reasons to start. The work is the same either way: measure first, then design.

Teresa Le, MSN, FNP-C — founder and nurse practitioner. She reviews your labs, designs your protocol, and performs your treatments herself. There is no rotating roster of injectors, and no handoff between the person who plans your care and the person who delivers it.

Over ninety markers spanning metabolic, cardiovascular, hormonal, inflammatory, and nutrient status — including panels most primary care visits never order. Every result is interpreted with you, not emailed as a PDF with the abnormal values highlighted in red.

See the full biomarker library →

Seventy-five minutes, minimum. We go through your history, your symptoms, and what you actually want to feel like — then order the labs that answer the open questions. You'll leave understanding what we're testing and why. The protocol itself is designed after the results are in.

It depends on the protocol and on you. Some patients notice shifts in energy or sleep within weeks; regenerative and structural work is measured in months, because tissue repair follows its own timeline. We re-test rather than guess, and we adjust at monthly follow-ups based on what the markers show.

Protocols are priced individually, and memberships are available for patients in ongoing care. Because coverage varies by plan and by service, the fastest answer is a direct one — call (602) 699-4208 or ask at your consultation and we'll walk you through the numbers before anything is scheduled.
