Why Choose Dr. Erez?
🚫 Zero-Guesswork Implementation
Navigating supplements and diets is overwhelming. We curate your entire regimen and send you direct links so you don't have to spend hours researching what to buy or wondering if the quality is good.
👂 Tell Your Story Once
Our comprehensive intake ensures Dr. Erez knows your full history before you even meet, so you don't have to repeat yourself or feel unheard ever again.
📈 Trend Analysis, Not Just Snapshots
Most doctors look at your labs in isolation. Because we see you quarterly, we track your biomarkers over time, catching subtle trends before they become major issues.
🔗 Connecting the Dots
You’ve likely seen specialists who only look at one body part (GI, Endo, etc.). We connect the dots between your gut health, hormones, and immune system to treat the whole person.
🧾 Comprehensive Insurance Support
We provide a ready-to-submit Superbill for your visits. Plus: If you have PPO insurance, we utilize it to cover labs whenever possible. If you need imaging or medication to address your root cause, we fight for Prior Authorizations to get them covered, so you don't have to battle the system alone.
🛡️ Our "Clear Path" Guarantee
We take the risk, so you don't have to. We are confident that our detailed process will provide the answers you’ve been missing.
The Promise: If you attend your 60-minute New Patient Deep Dive and do not feel you have a clear understanding of your health map or a tangible plan of action, simply notify us within 24 hours of your appointment. We will refund your money without question.
Discover Your Path to Wellness
Thorough Intake Process
Before we meet, I ask you to fill out a very detailed intake form that includes questions about your health history, environmental exposures, and specific concerns. This allows me to get a comprehensive view of your well-being and tailor my approach to your unique needs.
Based on your situation and budget, we'll decide on the necessary functional lab testing. From our visits, you will receive a superbill that you can submit to your insurance.


Comprehensive Testing and Treatment
Once I've assessed your situation, I design a specific testing regimen, supplement program, diet plan, and exercise routine tailored to you. I'll provide you with a detailed email with links and resources, so you have everything you need to understand and follow your personalized plan.
Your health journey doesn't end there. We'll stay in touch through emails, texts, or calls to ensure you're progressing well. Your follow-up appointments will be scheduled around your testing and treatment plan.


Open Line of Communication
You may have noticed in conventional medicine, the relationship between a patient and their doctor is often fleeting. Perhaps you've experienced those hurried appointments, rushed through in a matter of minutes. I understand how that makes people uncomfortable, even unwilling to fully share their concerns and goals.
That's why I'm passionate about creating a partnership with my patients. With me, you will never feel rushed or just another name on a list. I'm committed to a relationship where we openly discuss your health, your concerns, and your well-being.


Experience healthcare that's personal, proactive, and designed just for you.
With me, you'll find a medical ally who truly cares.

Accountability and Coaching
Unlike larger functional medicine practices, I run a one-man show. I personally read your emails, order your labs, and provide you with undivided attention and care.
I also act as a health coach, providing you with accountability – something often missing in healthcare. I use wearables like glucometers, Whoop, Oura, and Apple Health to keep track of your progress and even share my workouts with you. My approach is detailed, personalized, and focused on your optimal health.

Strive for Optimal Health
Whether you're here for weight loss, hormone optimization, reducing the risk of Alzheimer's, or just general well-being, I approach your care holistically. I look for risk factors that others might overlook, utilizing tools and tests that are specific to your concerns, and even offering cutting-edge screening methods for those focused on cancer prevention or cardiovascular health.

We Care About Patient Care

"Through his treatment, I've completely changed my prognosis and reversed multiple diagnosis."

"Within a few appointments Dr. Erez honed in on a diagnosis that all my other doctors had missed."
