Meet The Founders
Doctor Supervised Weight Loss
Co-founders Dr. Gerry Dembrowski and Dr. Jess Barnes applied decades of holistic patient care, Science, and research experience to develop the ground breaking 20Lighter weight loss program.
Gerry Dembrowski, D.C.
Dr. Dembrowski received his doctorate from Palmer College of Chiropractic West, and has been a primary care provider for twenty years. He brings integrative patient care experience along with homeopathic and holistic expertise to the 20Lighter team.
Dr. Jess Barnes, Ph.D.
Dr. Barnes earned her Ph.D. in Molecular Neuroscience at University of Illinois at Urbana-Champaign, and completed her postdoctoral fellowship in pediatric brain tumor research at the Dana-Farber Cancer Institute. She contributes a Science & research approach to the 20Lighter team.
Dr. Dembrowski’s 20 years of patient care laid the groundwork for the 20Lighter Program.
His experience ranges from daily patient management, to medical expert witness testimony, and seminar preparation and instruction.
Dr. Dembrowski helped negotiate and establish the Integrative Medicine Program at the Sonoma Valley Hospital in Sonoma, CA and ran a successful chiropractic and wellness private practice with offices on both coasts before choosing to focus his efforts on weight and metabolic health issues.
Dr. Dembrowski holds several specialty certifications including an International Certification for Neurological Organization Technique (N.O.T.), Certification in Applied Kinesiology, Sacral Occipital Technique Certification, and an Endocranial Manipulative Therapy Certification which at the time of certification, was one of only nine in the world.
Dr. Dembrowski spent time playing as a defenseman in the Canadian Junior Hockey Leagues, and in the U.S. Semi-pro and Junior Hockey Leagues. He graduated from Salem State University with B.S. as double major in Biological Sciences & Chemistry, and earned his Doctor of Chiropractic Medicine from the Palmer College of Chiropractic West.
Dr. Barnes brings a varied background including bench science, equity research, and venture capital experience to her role as co-founder of the 20Lighter Program.
Her previous positions include Director of New Ventures at Access BridgeGap Ventures, Senior Science Officer at Summer Street Research Partners, and Vice President in MEDACorp at Leerink Swann.
In 2007, she authored 13 issues of The Barnes Report, a life science research report distributed to 1,800 institutional investors. The Barnes Report highlighted new, interesting, and under-appreciated scientific advances in biotechnology and pharmaceuticals, which potentially translated into business opportunities.
Dr. Barnes was a fellow in the department of pediatric neuro-oncology at the Dana-Farber Cancer Institute and Children’s Hospital Boston. She developed novel functional imaging technology, evaluated the angiogenic basis of brain tumors, and tested experimental therapeutics in preclinical models of pediatric and adult brain tumors.
Dr. Barnes has been a grant recipient of both the Milheim Foundation for Cancer Research and the Midwest Breast Institute at Carle Foundation Hospital. She graduated from Worcester Polytechnic Institute with a B.S. in Biotechnology, and earned her Ph.D. in Molecular Neuroscience from the University of Illinois at Urbana-Champaign.

The dense green dots outline the bilateral Suprachiasmatic Nucleus at the base of the third ventricle (bright green vertical line) and sitting on top of the optic nerves (black area at bottom of picture). The ‘holes’ in the nucleus are tiny blood vessels in cross section. Slide prepared and photographed by Dr. Barnes
