how functional medicine can help
Bring vitality back into your life
Functional medicine is an area of medical practice that seeks to undo the conditions that caused an illness to occur. By looking at your overall health situation, a functional or integrative medicine practitioner can develop a highly effective treatment plan that targets the root cause of the problem, illness, or disease. This is a different approach than that of traditional medicine, which typically only treats the symptoms of disease.
Functional medicine utilizes a combination of traditional medical diagnostics and treatment options along with lifestyle modifications and personalized nutrition and supplement recommendations to restore patient health and vitality.
The end result is a long-lasting or permanent solution to chronic health problems, illnesses, and diseases.
meet our founder
Dr. Tamara Lyday
Dr. Tamara Lyday has been a functional and integrative physician since 2017. Prior to that she spent 11 years as a family practitioner, but was never quite satisfied with conventional medical approaches. Her mother’s illness and subsequent side effects to traditional treatments prompted her to learn more about integrative medicine and she has not looked back.
Dr. Lyday noticed how her mother's cancer treatment seemed to cause autoimmune disorders and additional health problems. She was frustrated by the fact that traditional medical care did not take into account the many different side effects that could occur as a result of a treatment plan.
She resolved to find a better way to provide care by restoring patient health and committed herself to becoming a functional medicine practitioner. During that time, Dr. Lyday saw many patients who had given up on ever receiving an accurate diagnosis, let alone a cure, for their illness.
She pursued training and certifications in functional and integrative medicine, including specialty training and certifications in the treatment of mold-related illnesses and Lyme Disease. At the time of her certification, she was one of only 26 practitioners in the world who were Shoemaker certified in mold treatment protocols.
After 4 years as a functional and integrative medical practitioner, she opened The Lyday Center to provide a dedicated resource for people who are suffering from mystery illnesses and ailments that don’t respond to conventional treatment and are seeking natural solutions to their chronic illnesses.
Dr. Lyday is personable, offering down-to-earth advice with compassion and a sense of humor. She is committed to picking up where modern medicine leaves off and will help everyone she meets.

our philosophy
The Lyday Center
At The Lyday Center, we work with patients to tackle the mystery illnesses that have been ignored, glossed over, or minimized by other doctors. We treat the whole person because we know physical ailments can have emotional roots and we understand that feeling ill can take a toll on your mental health and energy levels.
We will look at your health by examining your diet as well as your lifestyle, environmental factors, work, and stress levels. Together, we'll develop a plan to help you reach your health goals.
We know you're tired of looking for answers.
At The Lyday Center, you'll find them.
“When meeting with traditional primary care and specialists they made me feel like I was crazy for not wanting pills and wanting to try something natural, that the problems were in my head, etc.
Essentially, Dr. Lyday made me feel validated and we were on the same page from the start.”
