Client Testimonials

"Dr. Tassie saved my life. I have been sick for 25 years; I’ve been to major hospitals in Boston and New York, and every alternative medicine person, all to no avail. The Holistic Health Center is real medical care. Thank you!" — Charlotte A.



"When I met Dr. Tassie 9 months ago, I was the “exhausted mom.” Everyone always says, “Nap when your baby does.” I did everyday...the problem was, my baby was 2 1/2 years old! If I didn’t get something done by 2:00, I just couldn’t do it that day- I was a mess! Now, I feel fantastic! I am homeschooling my 2 older children, easily keeping up with my youngest, AND training for my 1st half-marathon! Dr. Tassie changed my life- “thanks” isn’t enough. " — Elisa B.

Thyroid Health

Thyroid health can influence nearly every body process including heart function, metabolism, reproductive health, cholesterol levels and more. It is closely related to adrenal gland health and can be evaluated by assessing blood, hair, use of thyroid questionnaires or basal metabolic temperature testing, (although least reliable). Typical blood tests include measurement of Thyroid Stimulating Hormone, T3, T4, Free T3 and Free T4. Additional tests include Reverse T3 measurements, Thyroperoxidase Antibody and Thyroglobulin Antibody testing for autoimmune dysfunction. Hair analysis evaluates how thyroid hormone is functioning at a cellular level by assessing calcium and potassium and can frequently detect an issue before it is identified in the blood. These levels can be within "normal limits" , however, the patient is still experience symptoms, This is where holistic approaches are extremely useful and restorative.

Adrenal Health

The adrenal glands sit on top of the kidneys and secrete steroid hormones throughout the day in a cycle called the circadian rhythm. Abnormal rhythm can influence many functions in the body including energy production, immunity, bone health, fertility, sleep quality and thyroid function. A simple non-invasive test can determine if you are in adrenal stress or fatigue. Dr Tassie likes to educate patients on what that means for them, and how to reverse the process and the hormonal cascade of adaption.


Gut Panel: The health of the gut is often described as the health of a person. It no longer matters if you travel outside of the U.S. or not to be exposed to a wide variety of parasitic infections and with the number of gut disorders there is no shortage of symptoms that people can experience on a daily basis. Clinical indications for testing of the gut include inflammatory bowel disease, diarrhea, constipation, fat/grain/food intolerance, bloating, heartburn, excess gas or abdominal pain.

Anti-aging and Inflammation

Chronic inflammation contributes to aging, especially to the cardiovascular and nervous systems. It is now recognized as one of the key risk factors for heart disease and stroke and viewed as a contributor to age-related degenerative diseases, such as Alzheimer’s. Keeping inflammation under control can be a part of anyone’s anti-aging strategy, but some people are more susceptible to chronic inflammation than others. Identifying how much inflammation is in your system is an important first step in the anti-aging process. Certain blood tests like an Erythrocyte Sedimentation Rate, (ESR), fibrinogen and C-Reactive Protein, (hs-CRP), can be general inflammation indicators. Additional blood tests may also be useful. Measuring gut health through the gastrointestinal panel or the overall biochemical profile through a hair analysis can provide a general profile of complete health and can guide decisions about diet and nutritional supplementation. Recommendations for anti-aging and reduction of inflammation levels may include changes in dental hygiene practices, exercise, weight loss, smoking cessation and including components of an anti-inflammatory diet as often as possible.
