About advanced health integrative and functional medicine.

Advance Health Integrative And Functional Medicine was founded by Dr Rashel Tahzib through her desire to deliver the best care to her patients and be able to do what is in their best interest.  Disappointed with the conventional medicine model of care for chronic health ailments she knew there is a better way, to address the root causes of disease, reverse disease and optimize health rather than manage disease and cause more disease by medical treatments and drugs that do nothing to address the root cause. 

She also wanted to be able to deliver the truth to her patients, and help them piece together the puzzle of how disease formed and why they may not feel well, and peel away the layers of disease back to a state of optimal health.   

Dr Rashel is a Functional Medicine physician, certified by the Institute for Functional Medicine,  she is among the first physicians in the nation and world wide to attain certification in Functional Medicine by The Institute For Functional Medicine.  She is also a board certified Family Medicine Physician as well as a certified in Anti-Aging and Regenerative Medicine by the American Academy of Anti-Aging Medicine. 

With over 20 years of clinical medical experience, her evidence based scientific approach and knowledge of Functional Medicine, combined with her personal experience with the health and disease process leads to the evolutionary personalized medicine she offers that works remarkably well with her patients.   Dr Rashel works very closely with each and everyone of her patients at Advance Health Integrative And Functional Medicine delivering concierge functional medicine.  Her patients become like family in the way they are cared for. 

Dr Rashel Tahzib at Advance Health Integrative and Functional Medicine practices Integrative medicine, offering the best of what treatments are available that are safe and effective and by the most natural means possible. Dr Tahzib also truly practices like an investigator, always doing extra, deep research when there are unanswered questions, and takes extra time providing information to her patients, because information is power and ultimately her goal is to put the power back in your hands where it belongs so you can live a long life filled with health and vitality, independent of drugs, debilitating side effects and health deterioration.

The central goal of her clinical practice is to address the root causes of your health concerns and cultivate healing and long-term well-being, rather than temporary fixes that often worsen root problems.  She routinely cares for patients who have been to numerous other doctors, clinics, and medical centers, including holistic clinics, and have not gotten results answers, or the correct treatment needed to restore their health and is able to peel away the layers of disease and effectively partner with and pave the correct path, diagnostics and treatments to restore health for her patients.

Health Is Your Birth Right! And You are Unique, Just ad your Health Care Should be.

My goal is for you to avoid the unnecessary suffering that arises when health problems are not properly evaluated and treated and the tumultuous journey that goes along with that process. Many patients I meet have seen numerous doctors, and alternative medicine providers prior to our meeting and do not have clear answers or good results.

Most patients that come to us have been failed by conventional medicine in some aspect, they have been misunderstood, misdiagnosed, unsuccessfully treated, and even created or worsened their health problems.

I have over 25 years of experience helping people find the answers to their health problems, by shedding light on the truths about health and disease and the root causes of disease in each unique individual.

One of my main goals is to when possible help you avoid the unnecessary side effects of pharmaceutical drugs and invasive surgical procedures and to provide you with empowering information about your health, the root causes of your ill symptoms, and offer you treatments plans that will nourish your health and well-being not only for today but for a lifetime.

I believe that health is our birthright and that our body intrinsically has the blueprint for optimal health and well-being. Our task is to partner to identify, and treat the root causes that are standing in the way and take your system off track.

Ultimately each individual patient and their unique story is far more important and powerful than the disease name and just as each individual is unique so should their medical treatment be, personalized and unique.

Toxicity, gastrointestinal dysfunction and emotional trauma in the milieu of genetics and environment are the gateway to disease. While positive emotions, whole organic foods, movement, nutritional supplements, and the body’s detoxification capability are the keys to healing and well-being.

However, many physicians don’t take the time to evaluate these unique factors, nor study them on an ongoing basis, ignore them or worse just deny that these facts exist.

Although the conventional diagnosis-pharmaceutical drug model works extremely well for acute care such as fighting acute infectious diseases or attempting to resuscitate a cardiac arrest patient for example it does not work for the modern-day chronic disease epidemic that millions are suffering from such as autoimmunegastrointestinal, cardiovascular disease and diabetes, obesity, allergies and other inflammatory diseases.

Functional Medicine addresses the underlying causes and multifactorial triggers of disease and is designed to reverse the disease process rather than mask or ‘manage’ disease symptoms for life.  Every One of you deserves the best care possible, everyone is unique, just as your health care should be. Functional Medicine creates an honest and effective path for the restoration of optimal health and well-being. 

Let's get to the bottom of your fatigue, gastrointestinal problems, brain fog, weight gain, sleep problems and other other symptoms you feel and eliminate them for good before they lead to other more serious health problems. Together We Will:

Investigate all aspects of your health, including genetics, environment, toxin load and exposure, diet and nutrient status, physical activity, stressors to identify the root cause(s) contributing to symptoms and or illness like gastrointestinal microbial imbalance, inflammation, toxicity, nutrient deficiency, hormonal imbalances, immune dysfunction,

Analyze not only standard labs but also advanced diagnostic testing as well as functional testing to reveal the underlying dysfunctions that are contributing to symptoms.

Develop Customized and personalized, integrative treatment plans. That include targeted nutrient replenishment, detoxification, gut restoration, exercise, diet, with immediate support of stress, sleep, energy, and mood.

Treat deficiencies and metabolic imbalances that contribute to chronic disease with an individualized, comprehensive approach that includes targeted research based nutraceuticals, bio-identical hormones, amino acids, diet, exercise, stress management techniques, and if needed medications.

Empower and educate you to implement customized functional medicine recommendations and lifestyle interventions to optimize your health not only for today but for years to come and the entirety of your lifetime. Once empowered with the tools you need by shedding light on what are the actual problems at play you are in a position to stay healthy for a lifetime.

I strive to deliver the most effective treatments, and engage in a partnership with each patient empowering you with the information needed about your unique biochemistry, nutrient status, hormone metabolism, genetics, microbiome, toxic burden and environment with the goal of becoming independently healthy for years to come and encourage each of you to take an active role in restoring and optimizing your health in this partnership. I look forward to working with you and embarking with you on your journey to optimal health and well-being.
