About Tranquilo

Tranquilo was formulated by two brothers - one an entrepreneur and experienced corporate finance executive, and the other, a Board Certified MD specializing in both Neurology and Sleep Medicine.

Mark Maraist - CEO

Mark, a CPA licensed in the state of Florida, is both an entrepreneur and experienced corporate finance executive. He has held several senior positions with both multi-billion international companies such as Tyco International and Compass Group PLC as well as entrepreneurial businesses such as Bravo Brands. He has extensive food/beverage and health food supplement experience. Mark, a native Floridian, enjoys his time as a father and is passionate about fitness. He obtained both his undergraduate and graduate degrees from the University of Florida. 


Dr. Michael Maraist

Michael Maraist - MD - Chief Medical Advisor

Dr. Maraist is board-certified in both neurology and sleep medicine. He completed his undergraduate work, medical school training, residency, and sleep medicine fellowship at the University of Florida in Gainesville, Florida. He is a native Floridian and father of three, happily married to his wife of 16 years. Dr. Maraist has always believed in the use of scientific-based medicine combined with creative ingenuity to treat “the whole person” when he cares for his patients. This was the approach used in development of the Tranquilo formula.
