About Dr. Anderson

Dr. Loy Anderson combines her 25 years’ experience in western medicine with the innovative and intuitive power of functional medicine to provide the best of both worlds.

After treating chronic disease for decades, she noticed her patients never really got well. While traditional medical care is excellent at dealing with acute care and health emergencies, Dr. Anderson started to observe holes in the approach. 

In 2010, after experiencing burnout, she learned that to care for others, she must first care for herself wholly— physical, spiritual, emotional, and mental— the essence of functional medicine. 

After attending a conference called “Heal Thy Practice” in 2015, she was again led to functional medicine and decided to commit her career to the cause. Loy says, “I will never forget the first day at that training; I felt like a parched traveler who had stumbled on an oasis and could drink my fill!”

In May of 2017, she opened the doors of her practice, Thriven Functional Medicine, equipped with the tools to help people achieve radiant, vibrant health. 

“I love what I do, and the very best part is seeing people reclaim themselves and achieve their life’s purpose.”

Dr. Anderson is passionate about educating and has lectured on women’s health, stress management, hormones, brain health, and of course, sleep.
