Daniel Stickler, M.D.

Co-Founder and Chief Medical Officer

Dr. Daniel L. Stickler is the Co-Founder and Chief Medical Officer of The Apeiron Center for Human Potential and Chief Science Officer for Apeiron Academy.  He is the visionary pioneer behind systems-based precision lifestyle medicine, a new paradigm that re-defines medicine from the old symptoms based disease model to one of limitless peak performance in all aspects of life. A physician to high-performing executives and entrepreneurs who want to upgrade their current state, he’s also an author, speaker, blogger and podcaster. He is the Medical Director for the Neurohacker Collective, a Google consultant for wearable technology, epigenetics, and AI in healthcare and a guest lecturer at Stanford University on Epigenetics in Clinical Practice.​ He discovered that lifestyle was the key to creating an optimized life and his journey to find the ideal approach to optimizing human potential took him on a path through functional medicine, alternative care, holistic, naturopathic, and age-management medicine. Each modality fell short of the outcome of creating a truly optimized human mainly because they focused on the disease model of treating symptoms as opposed to a model that focuses on human systems, homeostatic balance and optimization. In 2008, a new world opened through the lens of genetics and epigenetics and his near obsession like fascination of the potentials for personalized human systems design led to the realization that we truly have the ability within us to take charge of our destiny and become the architects of our evolution.


Mickra Hamilton, Au.D.

Co-Founder and Chief Executive Officer

Dr. Mickra Hamilton is Co-Founder and CEO of Apeiron Center for Human Potential/Apeiron Academy, and a Colonel and Human Performance Subject Matter Expert in the United States Air Force Reserves. She is a “Human Systems Designer,” and creative disruptor in the field of Epigenetic Human Potential Coaching creating a new paradigm for what is possible for human performance and potential.  Dr. Hamilton skillfully works with a systems-based precision approach to optimize the performance and potential of the human system by leveraging genomic and epigenetic lifestyle strategies along with leading edge research and technologies. This personalized, evidence-based approach addresses the physiological, emotional, mental, and energetic aspects of the “human system” to enhance the human experience, both in how we interact with our internal and external environment and how this impacts the collective environment.   Dr. Hamilton knows that homeostatic balance and thriving well-being is the very scaffolding of a life well lived and the beginning of a remarkable journey into the realms of limitless human potential.

Dr. Hamilton has always had an appetite for the adventures of life and the endless opportunities available to upgrade the human experience. Her path to optimized living through enhanced performance and potential began early with the questions, “What are the limits of human existence in one who knows no limits?”  “How does the human experience change when all the perceived limitations are removed?” These questions charted the course for a lifelong quest for the answers. Significant training, discipline, focus and sustained actions over time resulted in the experiential knowing of the limitless nature of self and other.  Recognizing that everything matters in our interactions, she consciously designs her experience to live life on purpose with a purpose in service to self and service to others, fully aware that they are one and the same.

Ryan Lester, PA-C

Physician Assistant

As a Precision Medicine clinician and Epigenetic Coach, Ryan has been a Physician Assistant for over a decade and is on the forefront of the rapidly evolving field of health optimization and human longevity.  As a graduate of Rochester Institute of Technology, in Western NY, he began his career in Emergency Medicine and Acute Care.  He transitioned to Orthopedic Surgery where he eventually specialized in lower extremity Joint Replacement.  Having performed thousands of surgeries, he received his Certificate of Advanced Qualification in Orthopedic Surgery.  Although his work in Acute Care and surgery was impactful, he began to realize the limitations of a healthcare system that operates in a sick care model, focusing primarily on treating active disease.  He realized that a paradigm shift was necessary to empower people to understand that through knowledge of the Foundational Pillars of Health (nutrition, exercise, sleep, stress reduction), one can truly take control of their life and well-being.  Ryan has training in Dietary Epigenetics through Stanford University and holds a certification in the Clinical Application of Therapeutic Peptides.  He now focuses on restoring balance of the body and mind and works with his clients to push the limits of their inherent potential; ultimately aiming to optimize their lifespan, health span, physical performance, cognition, and emotional well-being.
