A Smarter, Root-Cause Approach to Lifelong Health
At Princeton Integrative Health, we believe lasting wellness begins by understanding why you’re experiencing symptoms—not simply masking them. The PIH Method combines Functional and Integrative Medicine, advanced diagnostics, and personalized care to uncover the root cause of illness and help you achieve vibrant, long-term health.
Our Philosophy
We Treat People, Not Just Symptoms
Traditional medicine often focuses on managing disease after it appears. The PIH Method takes a different approach by identifying the underlying imbalances that affect your health. We look at how your body functions as one connected system, creating personalized strategies that restore balance and support lasting wellness
- Root-Cause Resolution
- Personalized Care
- Evidence-Based Medicine
- Long-Term Wellness
The Tools Behind the Method
Every treatment recommendation is carefully selected based on your individual needs. Rather than offering one-size-fits-all solutions, we combine proven therapies and advanced technologies to support your personalized health plan.

Thank you Dr. Leonti!!!Posted on Google Elaine StewardTrustindex verifies that the original source of the review is Google. I am so grateful to be working with Christina Warner! She is exceptionally knowledgeable about hormone health. The staff is super friendly and helpful. I can't wait to engage in the services they provide!Posted on Google Kimberly DixonTrustindex verifies that the original source of the review is Google. My husband has taken a break from chemo due to the negative side effects to his body and internal organs.i researched IV Therapy, which led us to PIH. These ppl are incredible and the options they offered to help reinvigorate my husband’s immune system initially included Oxygen therapy (never offered through traditional chemo and immunotherapy) & mistletoe injections (do your research). For the first time in almost a year, I saw my husband truly resting. In as quickly as 1 week. If you’ve given everything else a try, and nothing is working, come here. Things will change and you’ll have options for all your healthcare done holistically and homeopathetically.Posted on Google Amy WoernerTrustindex verifies that the original source of the review is Google. I have struggled to feel well for over a decade despite eating clean, daily fitness, prioritize sleep, and doing alllll of the things. I was overwhelmed, defeated, and heartbroken to see myself exhausted and unwell during these precious years with my four young children. Dr. Vinny was the first doctor to really hear me and give me hope. He is as warm and caring as he is knowledgable. After meeting the rest of the PIH team I was even more certain that becoming a member was the right decision. Brianna is a very smart and easy to connect with. Her insights regarding gut biome and digestion have already created positive changes. Rupali is another terrific support. Her calm energy, reassurance, and suggestions are so valuable as I navigate life around my healing. The entire staff is accessible and genuinely dedicated to the care of their patients. I can always reach someone easily during business hours and messages through the portal are responded to quickly as well. I can’t say enough about PIH. If you’re feeling hopeless about yoke health, give them a try, you will be so grateful. You deserve to feel heard, supported, and well.Posted on Google Michael and Beverly MillsTrustindex verifies that the original source of the review is Google. Staff is very helpful with explaining and administering treatmentPosted on Google I TTrustindex verifies that the original source of the review is Google. Disappointing experience. Dr. Leonti dismissed my concerns and pushed me to join his program. Requests for a certain care were ignored and calls went unreturned. The front desk staff was rude, especially one woman with an accent. It's clear they only care about promoting their own agenda instead of helping for the greater good. Would not recommend.
