    Our philosophy

    Our philosophy is simple: healthcare needs to change. ‘Find the provider who takes you off drugs, not the one that keeps you on.’ This has been our motto since day 1: allow your body the chance to fight, and beat, the attacking elements that are constantly swirling.

    You may not know this, but everything you need to fight disease is already inside you. The human body is among the most intricate, complicated, beautiful structures to have ever existed. Today’s culture has been nurtured to believe that pharmaceuticals are the answer to disease: they’re not.

    Preventive care is the single most important factor to long-term health and old age. We’re not here to change you. We’re here to guide you back to balance.

    I have been going to Retreat for about six months now and am thrilled with the results and guidance I have received. The changes to my body and overall health have been fantastic but I feel much better knowing that the path was rooted in principles of habit forming, behavior building, truly sustainable changes.As someone who has also grown wary and skeptical of healthcare due to experiences in the 'traditional' system, it was also refreshing to have the team approach me about moving to less frequent visits. I have so much respect for that approach and feel so confident that this team is truly invested in the right plan for each individual and open to catering your visits in a way that makes sense for where you are and how you are progressing.Without any exaggeration, I would describe my experience so far as life changing and I am very grateful to the team at Retreat that has also been great to my mother and her husband as well.

    Retreat has truly helped me take control of my health! I've been a patient for over a year now and have found out more about my own body, what nutrients it lacks and what works best for me. I started doing monthly IV's (as someone who is typically pretty dehydrated) and have found that I didn't get sick for over 8 months now - which is unheard of for me. I used to suffer from chronic sinus infections (including twice each winter at a minimum) and I haven't had one in a year!This service does not hit my insurance but is the best way to invest in myself - highly highly highly recommend!!!
    This treatment program has changed my life.Upon my first consultation I was asked what my goals were when considering my heath.Weight lossBetter sleepIncreased energyHelp with extreme inflammation.As I enter my 4th month of treatment and following the program Irina put together the results are as follows:Zero inflammation in my bodySleep soundly using nothing to help me fall asleep.Loss of 17 poundsEnergy that boosts my workouts as it was 15 years ago.What else is there to say? This a well-planned scientific approach to regaining your health.It is NOT difficult.I have recommended several people to Retreat and they are all succeeding and loving it.I'm very excited to continue to reach my goals and attain my maximum health benefits.100% onboard and now I know this is the way to reach my goals and maintain strong health benefits.

    I learned about Retreat Care Group through my colleague and it has been nothing but a great experience with the entire team, they are always there for you at any time you need an answer.When I met with Irina I was constantly getting sick, I had low platelets, low iron, low energy, blurry eyes, headaches and others. Irina looked deeper into why I was experiencing issues through blood panels. She educated me on what was going on and made recommendations in my diet and prescribed supplements based on her findings. Before I met Irina I was seeing a hematologist and my regular physician every 3-4 months for blood work and for years none of them was able to figure out was going. They only recommended monitoring my platelets and putting me on supplements for iron deficiency every other month.I highly recommend this place to anyone looking for the proper guidance to be a healthier you.

    Retreat has been a life changer for me. I have struggled with weight, anxiety and depression, stomach pains and problems, fatigue, sleep troubles and more for most of my adult life. Retreat runs extensive bloodwork and from that recommends a program that is specific to your body's needs. I have lost 30 pounds since starting and my stomach is much improved, my depression and anxiety have become drastically better, I have more energy and I sleep better and my bloodwork has showed improvements in my health! Irina Frenkel and her team and wonderful. I would highly recommend Retreat if you are looking for a wholistic and sustainable way to improve your health.

    Retreat Care Group is not only a great provider but a great environment to be apart of. Starting with the office manager, Jennifer, your time with Retreat is very simple, easy, efficient, and most important successful all thanks to her. I never have to worry about excessive papers, never seeing my receipts, confused on how to view my documents, etc. I can always count on her and I know Jennifer is there to help if need be no matter what. Everything is so easy to manage and constantly up to date. In regard to the provider, Irina is the best! She really try's to understand each patient and specializes their needs by a case by case bases. Not only does she make you feel important/valued, she makes you feel heard which can be difficult at normal doctors offices. I would without a doubt recommend Irina for any of your needs and especially if you are committed to make a long lasting change. And your package is created for YOU which is the most important part. Great team. Great building. Great results.
