About Success Orthodontics - Mayfield Heights
An underbite corrected with braces alone under Dr. Felix Gen, avoiding jaw surgery, is one of the results reviewers highlight most.
Dr. Felix Gen and the team draw praise for treatment outcomes that reviewers say exceed expectations, from corrected underbites without surgery to complete smile transformations. Young children and families with several kids in treatment come up often, and the office is noted for working through multi-year cases, from two-phase early treatment starting around age seven to longer three-year courses that finish on schedule. Warm, welcoming staff and a modern office round out what reviewers mention.

Dr. Gen is so nice and so is his staff. Any concerns you have he always makes sure to address them very professionally. And he is always there to make sure you have a great smile.
Finishing my orthodontic treatment has been such a rewarding experience. I’m truly grateful to the entire team for their kindness, professionalism, and attention to detail throughout the process. They made every visit pleasant, and the final results exceeded my expectations. I especially appreciated the excellent communication and that the office staff speaks Russian, which made the entire experience even more comfortable and welcoming. Thank you for giving me a smile I’m proud of. I highly recommend this practice to anyone looking for outstanding orthodontic care!
