Nancy Ann Lark - Registered Dietitian Milford | Optimal Health Solutions - NancyHi, I am Nancy Ann Lark. I am an Integrative and Functional Medicine Registered Dietitian Nutritionist, Exercise Physiologist, and Wellness Coach who specializes in getting to the root cause of health issues.

Today, I take my training, both professional and personal experience, consider the timeline of your life, and take an in-depth look at various health factors and connect the dots to make sense of your unique health and wellness challenges.

Before I got to where I am now, I had my own health struggles that motivated me to thoroughly explore wellness.

My Approach

Nancy Ann Lark - Registered Dietitian Milford | Optimal Health Solutions - myjourneyMy Journey Toward a Healthy Life

From as early as I can remember, there were signs that my physiology was out of balance. I had repeated ear infections as a child that persisted even with repeated bouts of antibiotics. When I was ten years old, I was just overweight enough for my parents to take me to the doctor, who put me on a diet with amphetamines. While I had some success losing weight, I gained as much in emotional baggage in the process as I had lost weight.

As I got older, I developed a passion for preventive wellness, and I focused on educating and motivating patients in a healthy lifestyle as I gained personally useful insights along the way. 

But even though I walked the walk, over the years I began to develop a cascade of other health problems.  I was struggling with autoimmune, energy, fatigue and pain issues when I found functional medicine 14 years ago and started on the long road to decipher the puzzle of me.  And the journey continues today.

It was (and is) that journey that has motivated me to continue to study and research the physical; brain and spirit and emotional components of wellness to understand how we can create balance and allow the body to heal itself and restore health.

Lifestyle Medicine Health and Wellness Coach; Exercise Physiologist, Brain Health Transformation Coach

For most of my early career, I specialized in preventive wellness in hospital and corporate settings and in private practice. As an RDN/Exercise physiologist for Crittenton Hospital's Weight Management Center's program, and then as the Wellness Coordinator for Rochester Center for Obesity Research and Treatment, (RCORT) I developed patient protocols for weight loss while maintaining muscle mass and optimizing body composition using resting metabolic rate measurements.

For over 30 years, I have been motivating, educating, coaching and encouraging clients to wellness by creating a safe, non-judgemental, caring space for transformation and learning.

Integrative and Functional Medicine Registered Dietitian Nutritionist; Certified Brain Health Coach

In 2005 I took a position at The Center for Personalized Medicine where I was mentored by the founder of the Fellowship program in Anti-aging, Regenerative and Functional Medicine (A4M), which is now called, Metabolic Nutrition and Medicine.

By 2008, I had completed the Fellowship Program (A4M) as an Advanced Fellow, and in 2010 went on to become on of only two in the first graduating class of a newly established MS in Medical Sciences degree with a concentration in Metabolic Nutrition and Medicine, at the University of South Florida, School of Medicine. If was the first international program of its kind.

Certification as a Brain Health Coach with a focus of Neuroscience, through the Daniel Amen MD Clinics adds a powerful tool for assessing brain function, and expanded the window through which I look to create powerful and customized wellness programs for my clients.
