Dr. Giles
Medical Director
Dr. Giles is committed to elevating the standard of care in addiction medicine. Born and raised in Southern California, Dr. Giles completed his undergraduate degree in molecular biology at the University of California, Berkeley and earned his medical degree from the University of California at Davis. He completed a general surgery internship, an anesthesiology residency with an emphasis in cardiac surgery, and an additional year of pain medicine fellowship at UC Davis Medical Center in Sacramento.
Inspired by his own experiences in recovery, Dr. Giles shifted his focus to addiction medicine. For the past twenty years he has made it his career. He deepened his understanding in the field by earning board certifications from the American Society of Addiction Medicine (ASAM) and the American Board of Preventive Medicine (ABPM). His innovative, research-backed and time-tested methods challenge old dogmas to improve patient safety and clinical outcomes.
Author of the bestselling and well-reviewed Outsmart Your Addiction, and a frequent guest on television, radio, and podcasts, Dr. Giles is passionate about helping patients recover their health, restore their relationships, and find new hope living in sobriety.
Ian Lobell, LCSW
Clinical Director
Born and raised a New Yorker, Ian Lobell, LCSW, was living in Manhattan on 9/11, watching in horror as the towers fell. Once he got word that his family had safely evacuated, he did what came naturally—he ran straight toward the devastation. With full access to Ground Zero, he spent weeks in the thick of rescue and relief efforts, an experience that forever shaped his commitment to disaster mental health. Since then, he’s jumped headfirst into crisis response, whether it’s hurricanes, wildfires, or wherever people need help the most.
With over 30 years in the field, Ian has worked across various settings, helping people navigate some of life’s toughest challenges. And he doesn’t just talk the talk—he’s been through his own personal traumas and hardships, which fuel his deep empathy and no-nonsense approach to healing. He’s particularly passionate about providing clinical therapy for veterans, active-duty military personnel, homeless populations and those battling addiction.
His academic adventure took him through Vassar College, Columbia University, Sorbonne Université in Paris, and Barry University, proving that you can collect degrees like Pokémon cards and still end up dedicating your life to helping others. He even spent a semester in the Soviet Union, where, without vodka and Marlboro cigarettes, he swears he would have frozen to death.
A lifelong learner, Ian has studied many languages extensively—but despite all that effort, he finds it hilarious that the only one he’s truly fluent in is English. At the end of the day, Ian is determined to bring heart, humor, and a whole lot of lived experience to mental health advocacy. Because if you can’t laugh a little while changing the world, what’s the point?
