Meet Our Leadership

Simon Leizgold leads operations, business development, and strategic growth at Happy Smiles Dental. He is responsible for everything that surrounds the clinical experience — how quickly the phone is answered, how clearly a treatment estimate reads, how reliably the schedule holds, and how the practice plans for the next five years rather than the next five weeks.

His working principle is straightforward: operational excellence is a form of patient care. When systems run well, appointments start on time, insurance is verified before a patient arrives, records move between team members without friction, and the clinical team can concentrate entirely on dentistry.

Simon oversees the daily operation of the practice — staffing, scheduling architecture, supply and inventory management, compliance, and the training programs that keep the administrative and clinical teams aligned. He designs the schedule around realistic appointment lengths so that patients are seen close to their reserved time and clinicians are not forced to rush.

He also owns the patient journey end to end. That includes the first phone call, intake paperwork, financial conversations, treatment coordination, recall communication, and post-treatment follow-up. Feedback from reviews and direct conversations feeds back into process changes rather than sitting in a report.

Simon directs the practice's marketing and community presence across the Treasure Coast, with an emphasis on honest education rather than promotional noise. The blog, the service pages, and the practice's local outreach all reflect that standard.

On the technology side, he evaluates and implements the systems the practice runs on: practice management software, digital imaging integration, secure record handling, online scheduling and forms, and communication tools. Each addition is judged on whether it measurably improves accuracy, security, or patient convenience.

Simon leads business development, strategic planning, and operational efficiency initiatives, along with practice acquisitions and long-term growth. He builds relationships with specialists, laboratories, and community partners, and evaluates opportunities to expand access to care across Port St. Lucie and the surrounding Treasure Coast.

Growth at Happy Smiles Dental is deliberately paced. Every expansion decision is measured against a single test: will patients receive the same standard of attention afterward as they did before? If the answer is uncertain, the plan is revised.
