On today’s episode, Dr. Mark Costes sits down with Dr. Dennis Hartlieb to share an inspiring personal journey, diving into his family’s sacrifices, his early days as a shy and introverted kid, and the unexpected accident that forever changed his career path. Mark opens up about his father’s immigration story, coming to America with limited means but boundless ambition, a foundation that shaped Mark’s own resilience. He recounts his traumatic baseball injury, which not only altered his smile but set him on the path to becoming a dentist.
Mark also shares how his entrepreneurial grit began long before dental school, starting with a catering truck franchise he ran while studying for an MBA—a humbling and formative experience he compares to running a dental practice. Listeners will hear about the perseverance that fueled Mark through multiple dental school rejections and into an academic journey marked by strategy and tenacity. This episode is a testament to how Mark turned life’s challenges into invaluable lessons, with a unique blend of humor, family dedication, and a relentless drive to succeed.
