How it works

From first consult to your first year.

Prévant is a 12-month concierge relationship, not a one-off appointment. Here's exactly what becoming a member looks like — from your free consult through your annual review.

Erin building a personalized care plan

Becoming a patient

Four steps to your first visit.

  1. 01

    Free 15-minute consult

    A short video call with our team to hear your story, answer your questions, and confirm Prévant is the right fit. No obligation and no medical advice — just a conversation.

  2. 02

    Enroll & complete intake

    Choose monthly or annual membership and complete our secure intake — full history, current medications, prior labs, family history, symptoms, and the goals you want to work on this year.

  3. 03

    90-minute new-patient visit

    Your first visit with Erin is 90 minutes — unhurried, comprehensive, and focused on root causes. She reviews your intake, listens to your story, and orders comprehensive baseline labs.

  4. 04

    Your personalized roadmap

    Your labs, history, and goals become a written care plan covering hormones, metabolism, sleep, cognition, cardiometabolic health, and prevention — with clear priorities for the year.

Your first 12 months

What each quarter actually looks like.

Membership is built around four unhurried visits a year, with direct messaging in between. This is the typical cadence — your plan is tailored to what you're working on.

  1. Months 1–2

    Establish the baseline

    Your 90-minute new-patient visit and comprehensive baseline labs. You leave with a clear picture of where you are today and the first two or three levers to pull.

  2. Month 3

    First quarterly follow-up

    Review early progress, re-check any flagged markers, and adjust the plan. Between visits you have direct messaging access for questions and small tweaks.

  3. Month 6

    Mid-year deep dive

    A more substantive visit to reassess hormones, metabolism, and any advanced testing ordered earlier. Refine the plan based on what's actually moving — and what isn't.

  4. Month 9

    Third quarterly follow-up

    Tune the plan, coordinate with any outside specialists you're seeing, and prepare for year-end labs.

  5. Month 12

    Annual review & year two plan

    A full year-over-year comparison of labs, symptoms, and goals. You leave with a refreshed roadmap for the next 12 months — including whether any specialty testing is worth repeating.

Between visits

Care that doesn't disappear between appointments.

Direct messaging

Secure messaging with Erin for questions, small adjustments, and check-ins between quarterly visits — no phone tag, no portal ping-pong.

Labs & specialty testing

Standard labs run through our outside partners (often billable to insurance). Specialty testing — advanced hormone, gut, cardiovascular — is ordered as needed and priced with you first.

Care coordination

We coordinate with your PCP, gynecologist, cardiologist, or any specialist you're already working with. Prévant is additive to your care team, not a replacement for acute care.

Ongoing progress tracking

Your labs, symptoms, and goals are tracked over time in the Prévant portal so you and Erin can actually see what's changing — not just react to one snapshot at a time.

If you're looking for a women's health care provider, you should stop reading reviews now and make an appointment with Erin Phamvan. She is absolutely wonderful and my appointment with her was the best medical visit I've ever had. She's up to date on current medical practices, listens attentively, is nonjudgmental and really cares about finding ways to improve your overall health. My appointment wasn't rushed at all and she followed up with me afterwards with recommendations based on my lab results. Someone else in the reviews said she found her forever doctor — I agree!

I mean it when I say that I found my forever doctor. Erin has always made me feel extremely comfortable, and that's important to find when it comes to a women's health doctor. Not only is she extremely knowledgeable, but she is non judgmental and makes difficult discussions easy to have. She genuinely cares about women and seeing them healthy and informed. I will be following her for as long as she's practicing.

I can attest to all of Erin's great reviews. I had her as my practitioner for my first and second trimester and I honestly chose her because we have the same first name. Sounds silly, but I'm happy I did. My baby was not planned and I had a lot going on but she never judged. She was very supportive of any decision I made with her there to guide and give me medical advice. She has comforting bedside manner and kept me informed about every test, ultrasound, diagnosis, etc. Erin really personalized my care and would sit with me during our visits to make sure every question or concern I had was addressed. She was very honest about possible results that may be unfavorable, but reassured me of her support and guidance. Even at one of the off site labs, the technician said she was familiar with Erin and thought she was one of the best and is good at what she does, assuring me that I was in good hands. I liked that she was younger and had a more modern, patient centered view on medicine.

Every single question I had was patiently and comprehensively answered. A full history was taken and listened to. As a result, Erin was able to sensitively communicate with me throughout any exams that were done. As someone with a lot of nervousness and apprehension with doctor visits, I left feeling informed, supported, and secure in my treatment.

Erin is very affable, leading to good, solid patient/provider rapport. She is also very knowledgeable, and communicates well with patients, addressing concerns in a clear and timely manner. I highly recommend her.

Erin Phamvan is simply and utterly a one of a kind provider. She is a beautiful, compassionate woman who took the time to get to know me and my situation. She literally went above & beyond measures to make sure I left feeling confident about our health plan. She listens with pure intention, makes you feel heard/seen and even ordered tests that no other provider would think twice of doing for me. She deeply cares about her patients and strives to get to the ROOT of problems. She's not like every typical provider from my past who has just shrugged me off and handed me yet another trial-and-error pill. I had only wanted to hug her and cry, but we couldn't with the pandemic. We are exactly on the same page and am so unbelievably thankful for her and her knowledge with nutrition and women's health!! Seriously. She is hands down the best and I've been through several since I moved here to Nashville. I feel so fortunate to have found a wonderful person and will root for her forever.

Erin is the best of the best. In every single appointment I've had with her she takes the time to truly understand my unique situation and make me feel heard. She is extremely personable and makes it feel like I'm talking to a friend! Erin is highly knowledgeable and studied, and even went above and beyond between my appointments to delve into books and podcasts regarding my case.
