Our Team

Christopher Keroack, MD, IFMCP

Chief Medical Director & Chief Executive Officer

As a functional medicine physician, I know that optimal health and balanced living is a realistic goal for every human being at every stage of life. Because of this, I am dedicated to assisting my patients in reaching their full potential in order to pursue life to the fullest. I help guide patients through foundational and personalized approaches to health that focus on dietary guidelines, activity regimens, stress management and sleep management that are specifically designed for each patient. Each personalized health and wellness plan takes into account the five foundational imbalances: Nutrition, Metabolism, Inflammation, Detoxification and Oxidation.

Sarah Lloyd

Chief Operating Officer

I have worked with Business-to-Business and Business-to-Consumer entities to help them grow and thrive for more than 30 years. My early training was under the Fortune 500 umbrella and then I crossed over to the consulting side and knew I had found my work “home”. In 1997 I had the incredible opportunity to incubate my own consulting practice for two years and then took it out on my own. Last year I joined New England Center for Functional Medicine as the COO. In its simplest form, I work with Dr. Keroack and the staff to continually improve the quality of our services and the health of our practice.


Sarah holds a B.S. from Springfield College and an Advanced Certificate in Marketing from the University of Hartford.

Modifiable Personal Lifestyle Factors

  • Sleep and Relaxation: Sleep and Relaxation: I have always been a great sleeper and didn’t understand why people had problems sleeping. Then I entered the perimenopause stage of life and became enlightened. I’m naturally an early riser, so I go to bed pretty early, usually by 9:00 pm and get up between 5:30 am – 6:00 am. I’ve learned it’s better to follow my natural rhythm and if I want to go out for a late night I take a nap in the afternoon so I can rally.
  • Exercise and Movement: I love being fit and was an athlete as a child and teenager. I’m not a huge fan of the gym, but I do love walking, yoga, Pilates and kayaking. I try to do something every day to keep my body moving and feeling fluid.
  • Nutrition: As a patient of Dr. K’s I’ve learned a lot about nutrition and what works for me. I follow a gluten and dairy free diet; both of these food groups make me feel crummy. Otherwise I eat mostly a Mediterranean diet. I also know that I don’t do well with high fat foods, so I’ve learned a lot about timing treats. My favorite indulgence is French Fries or a Gin and Tonic. I enjoy every bite or sip and then just continue on my normal plan. (Dr. K. has also helped me learn about supplements that help my system when I do indulge and that’s a game changer!)
  • Stress Management: I’m working on getting better at managing stress. I prefer active relaxation/stress management techniques such as gardening, kayaking, and walking in the woods. I meditate daily. I’m a big fan of baths and go for a massage on a regular basis. Several years ago when my eldest child went away to school, I got my first dog. Having my very own dog has been truly life changing. No matter how a day has gone, she is always right there, happy to see me, snuggle, and be a constant unconditional companion.
  • Relationships and Community: I live with my husband and one of our two daughters and three dogs. (The oldest daughter is launched). We make time almost every morning to have coffee together. We take a few minutes to be together so, as we go off into our very full and busy days we’ve started out connected. We also have dinner together almost every night. Even if it’s only a few minutes long, it’s a good way to close the day. I am very blessed to have extremely close women friends. I make time to share time with these women on a regular basis. On the flip side, I know I need to balance social time with time alone in nature. I regularly spend time in the Adirondacks alone and go on mini retreats several times a year to recharge and rest.

Modifiable Personal Lifestyle Factors

  • Sleep and Relaxation: I try to maintain healthy sleep habits. With a very active life working, grandparenting, and socializing with friends, sleep doesn’t always come first!
  • Exercise and Movement: I try to keep moving and that doesn’t always happen in a “formal” way. I am very active all day long. I make sure that I’m not sitting for long periods at my desk and make a point of taking my dogs for walks almost every day.
  • Nutrition: I try to balance life with proper diet. This means eating breakfast even though I leave early for work, bringing a healthy lunch and making dinner most nights. My husband and I like to eat out at restaurants, so I try to make good choices when we’re out.
  • Relationships and Community: I live with my husband and two dogs. I spend a lot of time with my children and grandchildren, which I really enjoy. My husband and I love sharing time with friends and have a very active social life.

Modifiable Personal Lifestyle Factors

  • Sleep and Relaxation: I have a VERY busy life with four children, a husband, home and job I love. Regardless, I tend to be wound for sound. To help support my system and get a good nights sleep I take a supplement every night,which really helps me sleep and sleep well.
  • Exercise and Movement: I’m currently training for my first full marathon! I had set a goal that if I could complete a half marathon in less than 2 hours then I would train for a full marathon. I never thought I’d do it. With Dr. K’s guidance around nutrition, pain management, injury and the importance of rest and recovery I met my first goal much sooner than I had anticipated and am now working on my second goal.
  • Nutrition: I prefer a vegetarian, gluten free diet. I’m noticing as I get older my nutritional needs are changing and I’m more sensitive to certain foods.
  • Stress management: Running is a big part of how I manage stress. I feel like I’m better in all the roles I play in life when I run on a regular basis.
  • Relationships and Community: I live with my husband, four children, 2 rescue dogs, 4 rescue finches, chickens and bees. We try to live as naturally and self sustaining as possible. Sometimes it’s nuts, but we have fun and laugh a lot!
