About Penna Orthodontics

Eight-month completion times for Invisalign, plus on-time appointments, come up again and again in reviews of Dr. Robert Penna's practice.

Dr. Robert Penna's practice sees frequent mentions of Invisalign and clear aligner treatment, with some patients reporting completion in as little as eight months, alongside phase 1 early treatment for younger kids. Scheduling stands apart too, with reviews repeatedly noting on-time appointments and easy booking around busy family calendars. Many families bring multiple children through treatment over the years, and reviewers often mention the front desk and technicians by their helpfulness with trays and braces. A few reviews describe treatment timeline issues, including a case needing extra braces after Invisalign for a stubborn tooth.

Dr. Penna is wonderful! He is kind, professional, and takes the time to make sure his patients feel comfortable. The office is welcoming, appointments are efficient, and we truly appreciate the excellent care. My son’s orthodontist had retired and He took over my son’s care and made the transition easy I highly recommend Dr. Penna.

That team is so awedome; front the front desk staff to the techs in back and Dr Penna himself! My daughter keeps breaking brackets and they are always accommodating! Shout out to Anahi :)
