Your Partners in Health: Meet the CNC Medical Team
Ethan Lazarus, MD

Jamie Shriver, PAC
Stacy Gill, RDN
Mary Ellen Doukakis, RDN
At CNC, we understand that there’s no one-size-fits-all solution for weight loss. No single meal plan, supplement, or medication can guarantee lasting results. Why? Because every person is unique—physically, anatomically, psychologically, and genetically. Add in factors like trauma, upbringing, education, and environment, and it becomes clear: your health journey is as individual as you are.
While sugar intake is down and the use of diets, supplements, and weight loss medications continues to rise, health issues such as cancer, GI conditions, premature death, and excess weight are also increasing. That’s why our clinic takes a whole-person, nonjudgmental approach to care.
Here, we don’t just focus on eating habits—we help you uncover the many influences behind your choices, so you can build a healthier relationship with food and your body. Our mission is to give you the knowledge, tools, and confidence you need for sustainable health and long-term well-being.
Our Medical Providers
Our medical team takes the time to understand your full health picture, reviewing your medical history and medications with you. We’ll discuss the risks, benefits, and costs of any treatment options transparently, so you can decide what’s best.
Yes, our providers can prescribe FDA-approved weight loss medications, but our care goes beyond that. We’ll recommend, refer, or prescribe any treatment or support that benefits your overall health—not just your weight.
Dr. Ethan Lazarus, MD
Double Board-Certified in Obesity Medicine & Family Medicine Past President, Obesity Medicine Association As our lead physician, Dr. Lazarus has over 20 years of experience helping thousands of patients understand that the struggle with weight is about biology, not willpower. He is a nationally recognized expert who tailors evidence-based medical treatments to each patient’s unique circumstances.
Jamie Shriver, PA-C
Jamie is a vital part of our medical team, working closely with patients to monitor their progress and provide ongoing support. Testimonials frequently praise her monthly check-ins and encouraging presence, which are key to helping patients like Cindi, who lost over 100 pounds, stay motivated on their journey.
Heather Thomas, PA-C
Heather is praised by patients for being “beyond helpful, responsive, and compassionate”. She is dedicated to ensuring every patient’s journey is safe and effective by combining medical oversight with nutritional counseling and regular lab work. Her support was instrumental for patients like Annette in losing 54 lbs and feeling strong and healthy.
Our Registered Dietitians
Registered Dietitians are the true nutrition experts. Each dietitian has at least a bachelor’s degree in nutrition, 1,000+ hours of supervised practice, and has passed a national board exam. At CNC, our dietitians meet you where you are and provide the education and support you need to lose weight—and keep it off.
Our dietitians will help you with:
- Label reading and meal planning if desired
- Physical activity recommendations
- Understanding contributors to weight gain across the lifespan
- Guidance on supplements and probiotics
- In-depth review of macro- and micronutrients
- Exploring lifestyle, behaviors, and body image
- Connecting you with additional resources (food tracking apps, support groups, etc.)
At CNC, we believe your health journey should be empowering, supportive, and tailored just for you!
