Dr. Frances Mark, Pharm.D.

With over three decades of experience and a deep commitment to holistic health, Dr. Frances is an advocate for those grappling with health challenges. As a seasoned expert in herbal supplements and natural remedies, she's dedicated her life to uncovering safe and effective drug-free solutions for a multitude of medical conditions, driven by her own unique sensitivity to medications.

In my 30s, I suffered from numerous miscarriages due to severe heavy metal and organophosphate toxicities that had gone undiagnosed. It was a challenging and painful period in my life, one that drove me to embark on a quest to reclaim my health.

Experiencing this at a relatively young age was incredibly disheartening. I was determined not to accept this as my fate and decided to channel my experiences into helping others who might be facing similar struggles. My journey to recovery ignited a passion for researching and offering the most sophisticated and cutting-edge functional testing to our patients, ensuring they receive accurate diagnoses as early as possible.

My own miraculous survival story adds a profound layer to my mission. Born prematurely at just 2.5 pounds in the 60s, in an era before NICUs existed, I overcame seemingly insurmountable odds. It became clear to me that I was meant to survive for a reason — to extend my hand and expertise to those in need.

From a young age, I discovered that I had a unique sensitivity to medications. Prescription drugs often resulted in a range of adverse effects that were more severe for me than for the average patient. This personal challenge set me on a path to find better, non-drug alternatives as well as natural healing methods.

My pursuit of knowledge led me to earn my doctorate in clinical pharmacy from the prestigious University of California, San Francisco. During the early 1990s, before the age of Google, I became a valuable resource at the UCSF Drug Information Center. I diligently researched and provided answers to drug-related inquiries from healthcare professionals across the nation utilizing my passion for herbal supplements and natural remedies to help individuals who, like myself, struggled with medication intolerance.

For over three decades, my life's work has revolved around discovering drug-free solutions for various medical conditions. It's an absolute honor to share my extensive knowledge of natural healing with you.
