Welcome To Advance Health Functional Medicine​

Health is Your Birth Right. A Refreshing Alternative

We are here to partner with you on the journey to optimal health and well-being. Dr Rashel Tahzib is and a Functional Medicine specialist, certified by the Institute for Functional Medicine and a board certified Family Medicine Physician.

With nearly 20 years of 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 with her patients.

The central goal of her clinical practice is addressing the root causes of your health concerns and cultivating healing and long-term well being, rather than temporary fixes such as simply masking symptoms with surgery and pharmaceutical drugs. One main goal is to help you avoid the unnecessary side effects of pharmaceutical drugs and invasive surgical procedures whenever possible 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.

Our practice uses the Functional Medicine model, a moving away from the conventional diagnosis-pharmaceutical drug model, or ‘name it and blame it’ game and toward systems biology and patient centered medicine designed to address underlying causes and multifactorial triggers of disease, and designed to reverse disease rather than mask or ‘manage’ disease symptoms for life.

Although the conventional diagnosis-pharmaceutical drug model works extremely well for acute care such as fighting acute infectious diseases, it does not work for the modern day chronic disease epidemic that millions are suffering from such as autoimmune, gastrointestinal, cardiovascular, diabetes, obesity, allergies and other inflammatory diseases

Once illness begins, multiple symptoms can overlap, such as fatigue, joint pain, weight gain, stomach issues like GERD and bloating, or hair loss, skin problems, hormone problems, concentration, muscle aches, mood changes, and diagnoses can overlap such as Hypothyroidism, PCOS, Irritable bowel Syndrome, Fibromyalgia, PMS, Insulin Resistance, Overweight, Hypertension, Depression, Anxiety, ADD, Autoimmune Disease, Arthritis. This can make it even harder for conventional doctors to shed light on the root causes of these problems using linear thinking and treating the body as separate isolated systems especially when pharmaceutical drugs are prescribed to mask the symptoms while each pharmaceutical drug can have numerous side effects that contribute to new ill symptoms and more of the very same symptoms and diseases they are trying to manage.

Dr Rashel interconnected beings, both within our body where every single cell is in communication with other cells and within our environment where every one of our cells is in communication with our environment. That means anything that we think, do, eat, drink, take, are exposed to, interact with and come into contact with at anytime from conception to present day all affects every single one of our cells and thereby our entire body. Therefore in order to reinstate health we must address the whole person that includes core imbalances such as nutrient deficiencies, toxicity and detoxification, hormone imbalance, gastrointestinal imbalance, nutrition, and lifestyle optimization that are central to the healing process.

Dr Rashel’s Treatment approach uses first thorough and complete history in utero to present day that helps her get to know her patient and how she or he has arrived to the point she is at today so that she can help uncover and address the root causes and start healing. She then uses advanced testing such as appropriate detailed hormone, adrenal, thyroid, immune, cardiovascular, metabolic, nutrients, amino acids, neurotransmitters, allergens as well as detailed Functional tests such as advanced intestinal cultures and markers, assessment of heavy metals and environmental pollutants, genetic testing and more.

The testing and clinical assessment is done with a unique approach using her invaluable skills and experience that has allowed her to create the unique approach and angle at getting right to the core of the problems and avoiding unnecessary tests and treatments that many undergo without being able to address and get rid of the problem. She helps the patients avoid the unnecessary Mary go round of testing even seen holistic or Functional medicine that some of the times is not what is going to make the patient better but rather just ends up costing them more.

Treatment Plans are tailored for each unique patient, no two are exactly alike, and can include customized nutriceuticals, amino acids, bio-identical hormones, thyroid supplementation, injectable vitamin therapies, dietary changes, lifestyle changes, and certain, medications when needed. Nutrient supplements prescribed are research based, highest grate in purity, and synergistic meaning each ingredient makes the others more effective and clinically proven to address the problems they are prescribed for being that the treatment plans are closely followed.

Dr Rashel partner’s with you to help peel away the layers that contribute to the disease process. She firmly believes that every one of us, when empowered to do so with the right guidance, has the inherent courage and capacity to reinstate the optimal state of health and well being that is our birth right.

Functional Practice Style

Health is Your Birth Right. A Refreshing Alternative

I am an advocate for the whole health and well-being of my patients and dedicated to identifying and treating the underlying root causes of disease in order to help reinstate a state of health and well being and minimize the years of life many patients spend sick.

Disappointed with the care that I received through conventional medicine and saddened by the fact that although wonderful in acute care, many of the treatments implemented by conventional medicine for chronic health ailments actually worsen or even trigger illness some of which can be chronic, debilitating and even life threatening, I developed my unique approach and protocols for wellness after decades of research, study and experience. Fundamental to my practice is the fact that we are integrated beings and all systems in our body are interconnected and in constant communication within and with the external environment.

Therefore, our environment from conception through life, tremendously impacts our health, and toxins, either physical or emotional can trigger and cause disease. These are factors that I address with each patient because wellness can never be achieved by addressing a single isolated symptom without regard to the remainder of the body as a whole or the root causes of where the symptom stems from. We will work together and take the time to decipher the root causes of your health ailments while we peel away the layers that have contributed to your current symptoms or state of health. Through this process It’s very common for most patients to experience large increments of on going improvement in their health as the layers that contributed to illness uncovered and addressed and have full resolution of symptoms.

My Practice is set up not with the goal of booking as many patients as possible in a day or hour like some, but in a way that will give me plenty of time to really listen to and hear you, and you plenty of time to tell your hear your story, so that I can make the best assessment and plan for your path to recovery and optimal health. You connect with a doctor who is actually trying to figure out why your health isn’t optimal and address the core issues no matter how complex. You receive answers to your questions and the kind of care I wish I had when I needed it years ago. And we get to even have some fun in the process, and the opportunity for you to learn about your own body, biochemistry, physiology and genetics and environment while we uncover and identify and treat the root causes of your symptoms or any Diagnoses.

This knowledge will place the power of health back in your hand where it belongs.

This is described beautifully by Dr. Jeffery Bland, in his book the Disease Delusion, that illustrates that diseases’ as we have known them until now, don’t in fact exist as a disease entity. They are symptoms of other underlying processes that once identified and treated result in the disappearance of the so-called dis-ease. Through the functional model of medicine I work with you to identify these processes and thereby markedly improve your current health and long- term quality of life.
