Transformations and Gratitude

We are grateful to our clients who share their success stories with us every day. Here is what some of them are saying:

Carlee L.

“Of all the physicians I’ve consulted over the years, you have to be one of the kindest. Despite being an undoubtedly busy person, you listen patiently to my questions and address them as carefully as possible. And, while some doctors might feel threatened by my desire to participate fully in my medical care, you appear perfectly comfortable with that role, making me feel comfortable in return. Underlying all this is your slightly ironic sense of humor, without which, as far as I am concerned, life is not worth living. I might arrive for an appointment full of stress and anxiety, but your calming presence enables me to depart with a modicum of peace. The older I get, the more I understand that body and mind are not really dichotomous, and clearly you realize that too. All by way of saying I feel very fortunate to have found a doctor like you to shore up my tottering health in this uncertain world.”

“As someone who tries ‘a new diet every three months,’ I began a search for a food plan that would be sustainable for my body and lifestyle. I was lucky enough to have met Jenna, who has been a consistent source of knowledge, accountability and leadership. I had a bingeing problem, an overeating problem and a generally unhealthy mind-set about food. Jenna’s program has been comforting to me mentally and has helped me to feel more normal. I tried to do this on my own for so long, and it just didn’t work. I refused to be the woman who, in 20 years or so, was still ‘dieting.’ Thanks, Jenna.”

In Their Own Words

Our clients come to us looking for more than a quick fix. They are looking for answers and lifelong solutions to better health.

“I met with Jenna to discuss my emotional and physical health. She spent time getting to know me. I walked out of her office feeling better about myself, my goals and my overall interest in developing habits to live a healthier, less stressful life. She is smart, professional and easy to talk to. I look forward to having Jenna in my life “forever” and to taking her well-researched and educated “prescriptions” for a better and fulfilling life. I’d advise anyone to spend some time with Jenna, even if only five minutes!”

“I am a type 2 diabetic who has been taking multiple medications to control diabetes, high blood pressure and high cholesterol. During a routine appointment in 2016, I discovered my A1C number was 10.2, the highest it’s been since I started tracking my numbers 12 years ago. In addition, my blood pressure was 146/80, my cholesterol was 175 (45 HDL, 82 LDL), my triglycerides were 236, and I had a small amount of protein in my urine. Dr. Leonti suggested a different plan of action to improve my numbers. Before making more medication changes, he suggested a low-carb diet of eggs most mornings, salads, nuts, vegetables, meats, almond milk and fruit. After one month, we checked my progress, and the trend was positive. At my next routine appointment, my numbers were significantly improved. My weight was down 32 pounds after six months. My A1C number was 6.3, blood pressure was 108/78, cholesterol was 130 (53 HDL, 57 LDL), and triglycerides were 99. These were the lowest numbers I had achieved in 12 years. We were able to cut my metformin and Avapro dosages in half. I definitely feel better than before and have more energy. I hope to see further improvement in my numbers, and possibly eliminate the need for medication, by maintaining my current eating habits.”

“I have a feeling that a lot of people look to integrative health as a fast track to skinny. I am not a client who came to Princeton Integrative Health intent on losing weight. When I came to Jenna, it was because I had intense stress coupled with a thyroid disorder. I could barely get out of bed or off the couch at night. After Jenna told me about the program options at PIH, I knew I was a six-month candidate. That’s because it usually takes me a while to achieve success at something. I am now five months into the program, and I can honestly say that with Jenna’s encouragement, I have been able to make changes for myself that I never would have otherwise. During the first three months, we worked to lower the stress in my life and to make dietary changes in a way where I didn’t feel awful doing them. I am not an easy client based on my history, but knowing I see Jenna every other week gives me an outlet and incentive as well as someone to hold me accountable for my own health, mentally and physically. As a patient of PIH, I have learned the science behind what is happening in my body.”

“My first appointment with Jenna and Dr. Leonti was refreshing and helpful. For 60 minutes, they listened closely to my long, intricate and complicated health history. Jenna and Dr. Leonti bring the best of functional medicine and Western medicine perspectives into one space”

“The first time I was going to meet with Jenna, I almost backed out. But a voice inside my head said, “Don’t do this, you need to go.” It turned out to be the best decision for me. I felt very comfortable and safe talking to her. Since I started the program, I have felt incredibly different in mind, body and spirit… a very good different. Change is challenging and can be scary. The support was strong from Jenna and Jackie, who also joined the group. It is amazing to me how learning to eat in a healthy manner has had such a profound impact on my life!”

“PIH is a companion and an ally in my quest to determine the root cause of my health problems and to maintain a healthy lifestyle. Through various medical tests and consultations with the team, I have gotten a clearer picture of the status of my overall health, possible factors contributing to my various health issues, and what we can do to address these. They never promised a quick-fix-for-all-your-health-problems-solution, but they are walking with me through the process.

The whole team is very friendly, approachable and helpful. I have already recommended them to my friends and will not hesitate to do so again.”

“I have fibromyalgia, chronic fatigue and arthritis. When I came to PIH, I was also experiencing painful stomach problems with gas and bloating.

After some pretty unique tests, I learned there was help for me! The nutritionist, Jenna Richardson, suggested some pretty drastic dietary changes, and I started to experience improvement shortly after I started them. I even lost some weight during the process!

Dr. (Vincent) Leonti and Patti McDougall were very helpful and supportive. The coaching sessions were conducted in an atmosphere that is ‘comfy’ and safe. I learned to trust their recommendations and knew I could depend on their support along the way. This atmosphere at PIH is much different from most doctor’s offices (where I think they rush you through an appointment due to insurance rules and often prescribe a medication after a very short period of diagnosis). PIH takes extra time and looks at the overall situation instead of treating just one symptom.

I’ve been so pleased that I’ve already recommended PIH to my friends. Attend one of their information sessions, and I am sure you will also be pleased to join them for a journey to a healthier you.”

“A few years ago, I was diagnosed with an immune system disorder called Sjogren’s syndrome, and the only treatment I was offered was a drug designed to treat malaria. It was a drug I would have to take for the rest of my life, and the only thing it would do is, maybe, help alleviate some symptoms.

I decided this was not the option for me. I had heard about integrative medicine and attended a free workshop at PIH. They offered information that immediately resonated with me, and I signed up.

After initial testing, we addressed my issues with natural supplements, healthy lifestyle changes and ongoing support through follow-up visits and coaching.

Today I am feeling much better, and many of my symptoms are vanishing. I would definitely recommend PIH to anyone who is tired of following the traditional medical route and not getting relief from their ailments.”

“I like the fact that Dr. Vinny (Leonti) has a conventional medical background that complements Jenna’s awesome fountain of knowledge and experience.

PIH has helped me tremendously with my autoimmune condition, and I have experienced significant improvement. In addition to Dr. Vinny and Jenna, Patti is a caring nurse and a great listener, and Jackie (the patient ambassador) will make you feel she has known you forever the minute you walk in the door.

I hope to continue co-caring for my health with them for years to come!”
