Leslie Espinola has spent more than 35 years in the dental industry, but that was never the plan. She studied forensic science and wanted to join the FBI, then took a job in her father's dental practice while she figured out her life, and never left. Today she is a Dental Executive Coach, Fractional COO, and founder of High Peak Dental Advisors, helping practices grow through better leadership, healthier culture, and smarter operations.

In this episode, Leslie explains what a Fractional COO actually does, why she travels to client offices three and a half weeks a month, and the leap of faith she took last year to start her own company after a career inside large organizations. She is candid about the difference between a manager and a leader, and the trap office managers fall into when they get promoted but stay stuck in the day to day.

Leslie shares the operational truths most practice owners miss: why good leadership is always about people, how culture prevents turnover, why so many owners stay disconnected from their numbers, and the sobering reality that a large share of dental offices are stolen from by a team member. She also makes a clear-eyed case for AI in dentistry, where it removes unproductive work so teams can stay patient facing, and why she has not seen it take a single job in the industry.

The conversation closes on the win she is most proud of: an office manager who was weeks from being let go and, after one hard conversation and six months of mentoring, became one of the best leaders Leslie has ever worked with. If you lead a team or run a practice, this one is full of practical, people first wisdom.
