Vice President of Compliance and Quality

Sherilyn Toro

Sherilyn was born and raised in New Jersey before relocating to South Florida in 2010. She was Banyan’s first female sober living client and became a Behavioral Healthcare Technician in 2014. Because of her remarkable work ethic, she was quickly promoted to Program Supervisor, then Director of Intensive Outpatient Operations. Sherilyn’s qualities were noticed by upper management, and she eventually moved into the Quality Assurance department as a QA Coordinator. After a few years, Sherilyn was promoted to National Director of Quality Assurance and is presently our Vice President of Compliance and Quality.

Sherilyn oversees all facility regulatory affairs and quality assurance, ensuring that Banyan adheres to the highest standards so that our patients receive the best possible care.

She is currently pursuing a master’s degree in business administration at Johns Hopkins University, with two specializations: (1) private and public sector leadership and (2) healthcare management innovation and technology. 

Sherilyn says sobriety, “gives me the power to live life presently, joyfully, and wholly. The shame, guilt, self-hatred, and hopelessness that I was trapped in for so long has disappeared, and I am blessed with opportunities to use those experiences to help others.” When asked what advice she would offer to someone struggling, she says, “advice is what people who haven’t been in our shoes give. We offer our experiences, then and now, as a guide for others to follow. Life is what it is supposed to be today; sometimes rough and sometimes blissful.”
