Medical Director

Dr. Estevez is a board-certified neurologist who has practiced addiction medicine at Serenity Lane since 2018. His unique background in molecular biology, neuroscience, and clinical neurology has shaped his understanding of addiction as a complex disorder involving changes in brain function, often influenced by trauma and other life experiences.

Born in Havana, Cuba, Dr. Estevez moved to Miami, Florida, at the age of three and grew up there, completing high school in the city. His childhood near the ocean fostered a lifelong appreciation for the water. During his youth, he spent many sunny days swimming, snorkeling, and scuba diving off Miami Beach and exploring the coral reefs of the Florida Keys.

Dr. Estevez earned his undergraduate degree in biology from the Georgia Institute of Technology, where he conducted research using Caenorhabditis elegans as a model organism. This work resulted in a publication in the Proceedings of the National Academy of Sciences. He subsequently pursued graduate studies in molecular biology at the University of Missouri–Columbia, earning his PhD. His doctoral research was published in the scientific journal Nature and focused on transforming growth factor beta (TGF-β) receptors, a class of proteins that have since been implicated in nervous system changes and adaptations associated with addiction.

During his doctoral studies, Dr. Estevez worked alongside physician-scientists who were exploring the clinical applications of his basic scientific research. Their work inspired him to pursue medicine, with the goal of translating scientific discoveries into better patient care. He earned his medical degree from the University of Missouri–Columbia in 1997. During medical school, he developed a particular interest in the evaluation and treatment of disorders of the nervous system, leading him to complete a neurology residency at the University of Pittsburgh Medical Center, where he served as chief resident during his final year.

Dr. Estevez's path to addiction medicine was shaped by his experience at the Hazelden Betty Ford Center. There, his interactions with patients deepened his conviction that addiction is a complex disorder involving the brain's regulatory systems, rather than a failure of willpower or character. He came to recognize the profound role that trauma—including psychological trauma and traumatic brain injury—can play in a person's vulnerability to addiction and in the course of recovery. He was particularly struck by the courage, resilience, and intelligence of the individuals he encountered, many of whom had struggled with the stigma and misunderstanding surrounding addiction.

In 2018, former Medical Director Dr. Eric Geisler offered him the opportunity to join Serenity Lane. Dr. Estevez welcomed the chance to apply his background in neuroscience and clinical medicine to help individuals and families affected by addiction. He remains committed to providing compassionate, evidence-informed care and to advancing a more nuanced understanding of addiction as a treatable medical condition.
