30-Minute Coaching Call

Nathan came from a family of Chiropractors which first piqued his interest in nutrition and physiology early on. Most of his adult life he’s spent traveling the world for work and pleasure, finding inventive ways to exercise.

Nathan took a deeper interest in the science of exercise and nutrition at 20, and with an engineering mindset looked to debunk the myths and strip down physique improvement to its most important, reliable elements for lasting change. He has hired and worked closely with some of the industry's biggest names to codify a set of practices that he has used for himself and many others looking to reverse and improve their physique.

With ten years of experience coaching he still travels and works as an marine engineer, but has found a real passion in helping others make lasting health and physique changes. When Nathan discovered the Green Door project he was very excited to join their team and be a part of the change they were offering the community.

When Nathan isn't coaching, you can find him enjoying cross-country travel on his motorcycle, training Jiujitsu, rock climbing, & finding the perfect powder to shred on his snowboard.

Shannon Morse

Shannon’s interest, desire and personal commitment to educating and developing the potential in her clients through nutrition, physical fitness and awareness stems from her belief that the body has endless possibilities when fueled and treated properly.

Her journey began over two decades ago when she was introduced to Pilates, a form of strengthening the body’s core movements through stretching, exercise, and muscle activation. This led Shannon into the fields of personal training at both the group and individual levels.

She received her certifications:

Pilates and personal training through BASI (Body Arts and Science International). (600hrs)
NPTI (National Personal Training Institute). (800hrs)
NASM (National Association of Sports Medicine) (300hrs) As her interests and skills in the practice grew, she expanded her practice to the classroom and became an instructor, teaching the NASM curriculum ( a 300 hour practical application and classroom coursework) to those interested in becoming NASM certified personal trainers. She is the founder of Ahmiel Personal Training Education and NASM certification prep.
Licensed Diet Doc Permanent Weight Loss Program clinician. Shannon understood the importance of diet and nutrition in the entire fitness equation. She came to realize that nutrition was the key to unlocking the body’s true potential when combined with a proper training program.

Lisa Kirby

We’ve all heard the saying that managing your bodyweight follows the 80/20 rule: 80% diet and 20% exercise. But, what does that really mean? As the Diet Doc of Clemmons, North Carolina, I’m here to help you navigate your journey of discovering that answer and finding a balanced solution that works uniquely for you!

Over 15 years ago, I found myself drawn to the health and fitness industry, working at training facilities for professional athletes, weekend warriors, exercise newbies, and everything in between. With such a heavy focus on physical performance for so many years, I was delighted to find the missing pieces to the puzzle – nutrition and mentality – upon joining the Diet Doc Lifestyle team. I’ve gone through the program myself and beyond the obvious physical results that I have achieved, as a mother of two young boys, I was equally excited about the seemingly endless non-scale victories: better sleep, increased and consistent energy all day long (for real), more patience, less anxiety, and a healthy, positive outlook… the list goes on and on.

At the heart of coaching is the primary objective to support and inspire people, which is a lifelong passion that I have pursued as evidenced by my choice of undergraduate studies in psychology, graduate studies in education, and current employment in higher education, in which I mainly support the wellness program for faculty and staff. Now, as the licensed Diet Doc Weight Loss Clinician for Clemmons, North Carolina and greater Winston-Salem area, I can apply my unique background and work experience to maximizing your goals.

Don’t like working out? No problem! Would you rather be in a Crossfit class than a desk job? Me too. I’ve got you covered, and you can eat carbs again! Don’t want to give up wine and cookies? Don’t worry… you don’t have to! I want you to experience the same freedom of eating to achieve your body composition goals while still accommodating your lifestyle choices.

In particular, if you are a mama-to-be, recently post-partum, and/or a parent who would like specialized assistance with achieving your goals while still keeping a happily fed family, I am excited to share with you all the tips I’ve gathered along the way!
