Leadership & Senior Advisors

Renata Fries, Founder & President

With over 25 years of professional experience in the health care industry Renata has worked to develop health care strategies, policies and has been responsible for resolving health care disputes. Informed by her professional work, but inspired by her role as a mother of two she has shifted her focus in the past seven years to nutrition and fitness. Despite a hectic professional life she has always found time to cook wholesome meals for her family and friends. Cultivating a family practice of well-being has always been a top priority; thus when she read an article in 2010 published by Minority Women’s Health that reported that four out of five African American Women were obese she was moved to make a difference in her community. EndsideOut reflects this new commitment to share information with others, particularly women. Renata is dedicated to advancing knowledge about the importance of well-being and commitment to a healthy lifestyle. She has worked with individual clients, community organizations and in K-20 educational settings.
