A Note from Our Founder:

Our Expectations: Your commitment and devotion to YOURSELF and as a result, to the program.

I’ve worn many hats in my life—entrepreneur, mentor, award-winning marketer, and proud mother of two incredible children. I built businesses from the ground up, advised Fortune 100 brands, and earned recognition along the way.

But behind the achievements, I was silently struggling.

At 5’3”, I weighed over 210 lbs. I tried everything—Keto, Atkins, juice cleanses, diet pills, vegan, vegetarian. I always lost some weight… but it always came back, often with more. I was stuck in a relentless cycle of hope and defeat.

It didn’t make sense. I was smart, resourceful, and determined—yet I couldn’t figure out my own body. The breakthrough came when I discovered that my struggle wasn’t just physical—it was rooted in lifestyle, mindset, and sustainable habits.

That realization changed everything.

Today, as a Harvard Medical School–trained Lifestyle Medicine Coach, I help others escape the same exhausting cycle. My program isn’t about quick fixes, drugs, or restrictions. It’s about evidence-based, natural strategies that create lasting change—nourishing your body, rewiring your habits, and supporting your mind and spirit.

This work isn’t just my profession—it’s my purpose. Helping others reclaim their health brings me more joy than any award or accolade ever could.

Are you ready to transform your life?

THOR Wellness Retreat Guest
I wanted to give a shoutout to Terry for helping me transform and lose over 20 pounds. I struggled with excess weight, which comes with high blood pressure, miscarriage from hypothyroidism, and hormone imbalances - all from not eating well, exercising and caring enough for my health and fitness. I was only 124 pounds in my mid to late 20’s and then after in mid to late 30’s I was above 167 pounds. Which brought in all types of health issues. I had a few difficult years - having older parents and a new baby to take care of. In addition to that, I decided to pull up all my energy and go to grad school for my MBA to get my career on track and unfortunately had a bad experience which added to losing my confidence to rock bottom. While I was going through all this, I was stress-eating and gaining weight. Terry who is my neighbor and friend for the past 15 years, went through similar issues and when I saw her going through the journey of being overweight and transitioning into a healthy and beautifully fit person --- her dedication to fitness and macro food, and her entire routine made me take the first step to start working on my own fitness goals. Terry helped me every step of this wellness journey. I call her my therapist, nutritionist, fitness instructor and life coach! She guided me with patience and perseverance. I had never lifted weights - she helped me accomplish my overall goal to a healthy mind and body. Today I have no high blood pressure, I lost over 20 pounds (154 to 133), I’m able to eat what I like and make sure my family also eats nutritious macro-friendly food. We have misconceptions that macros diet is going to be difficult and bland -- but that is not true. You can make it what you like and what fits your lifestyle. Portion it right and you can continue to eat whatever you prefer - not just salads. Combine the way you cook with macros so that you enjoy every meal. Terry guided me through all this step by step. Her experience and guidance helped me create well-balanced meals that I truly enjoyed while losing one pound a week. I would never have taken this path if I had seen Terry’s transformation. And I would have never achieved my goals in fitness, nutrition and shedding the extra pounds if Terry had not coached me with her technique. What I loved most is that she works one-on-one with you - not one size fits. All is truly individualized to you!

Terry, I love you so much and have learned so much from you and appreciate your help and guidance more than I can express.

We are doing great Terry. I hope all is well with you! Both Dianne and I are counting macros and drinking ginger shots each day. I’ve resumed daily ashtanga yoga and Dianne is doing some weight training. I even bought a Ninja and made frozen yogurt. LOL. I cannot thank you enough for inspiring these positive changes. Best wishes on your upcoming retreats, I truly hope to return to THOR sometime next year. Best, Vicki

Hi, my name is Karen and I'm 63. I started training with Terry last August and have already lost 17.4 lbs. In our last chat, Terry and I were discussing that I have been on a diet for almost 6 months. It took me by surprise because I haven't felt like it's been a diet. Learning macros hasn't seemed like diets of my past. Weight training has been a rewarding adventure and I'm looking forward to what 2024 brings.

What is Lifestyle Medicine?

Lifestyle Medicine Coaching combines the latest medical science with proven coaching techniques to help you create lasting, healthy habits. Unlike quick fixes or restrictive programs, this approach empowers you to make sustainable changes in every area of life—nutrition, movement, sleep, stress, and relationships—so you can prevent, manage, and even reverse chronic disease.

The Core Pillars of Lifestyle Medicine Include:

🍎 Nutrition – Adopt a whole-food, plant-forward way of eating that supports energy, vitality, and disease prevention.

🏃 Physical Activity – Create a movement routine that fits your body, schedule, and preferences.

😴 Sleep – Build restorative sleep habits that recharge your body and mind.

🧘 Stress Management – Learn techniques to calm your nervous system, build resilience, and restore balance.

💬 Social Connection – Strengthen the relationships that fuel happiness, health, and longevity.

What is the cost of the program?

Price is $300 per month. There is no minimum number of months required although we do recommend 6 months to experience the full benefit of the program.

How does coaching work?

We start by clarifying your goals and uncovering what’s been holding you back. From there, we create a personalized plan designed for your lifestyle and health needs. With ongoing support, accountability, and strategies to overcome obstacles, you’ll gain the tools and confidence to take charge of your health and sustain lasting results.

  1. Clarify Your Goals & Motivators – We uncover what truly matters to you and what’s been holding you back.

  2. Create a Personalized Plan – Together, we design strategies tailored to your lifestyle, preferences, and health needs.

  3. Ongoing Support & Accountability – Regular check-ins keep you motivated and on track.

  4. Break Through Barriers – We identify challenges and build solutions to help you succeed.

  5. Empower Self-Management – You’ll learn how to take ownership of your health and create lasting results.

  6. Evidence-Based – Every strategy is grounded in research, not fads or gimmicks.

  7. Holistic – We look at the whole picture- physical, mental and social well-being.

  8. Personalized – Your values, goals, and lifestyle shape the plan – not the other way around.

  9. Behavior-Driven – The focus is on building habits that stick for life.

  10. Collaborative – We work together as partners, with guidance and accountability every step of the way.

This is not about restriction or quick fixes. It’s about transformation. Lifestyle Medicine Coaching helps you build the foundation for a healthier, happier life. One choice at a time.

How will I benefit from working with you?

Lifestyle medicine coaching helps you take control of your health by improving chronic condition management, boosting energy and confidence and building habits that last. You’ll enjoy greater well-being in mind, body and spirit, while also reducing long-term healthcare costs through prevention and self-care. Some benefits include:

✔️ Better management of conditions like diabetes, heart disease, and obesity
✔️ More energy, confidence, and clarity in your daily life
✔️ Sustainable, long-term health habits (no more “yo-yo” cycles)
✔️ Reduced healthcare costs through prevention and better self-care
✔️ A greater sense of overall well-being – mind, body and spirit

How is this different from every other diet I’ve tried?

This is not a diet. It is a complete lifestyle transformation program that incorporates aspects of fitness, mobility, proper nutrition, emotional well-being, mindset, biohacking, hormone health and habit development. The combination of these modalities result in reduced stress, less body fat, increased strength and mental resilience.
