Meet Dr Rashel

As a Functional Medicine specialist in Los Angeles, California, and Denver Colorado my goal is to provide my patients with the highest level of personalized care, identify and treat the root causes of disease and help you avoid the unnecessary suffering that can arise from health problems that are not properly evaluated and treated and the tumultuous journey that goes along with that process.

About Dr. Rashel

Many of the patients that I meet have seen numerous doctors and alternative medicine providers prior to our meeting.

Most have been failed by conventional medicine as the approach has been misunderstood, misdiagnosed, unsuccessfully treated, and even created or worsened their health problems.

I have over 20 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 autoimmune, gastrointestinal, 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, every one of you is unique, just as your health care should be. Functional Medicine creates an honest and effective path for the restoration and protection of optimal health and well-being.

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.
