Dr. Mark Guevarra is the founder and orthodontist of Level Orthodontics, a practice he built on the belief that a confident smile can change everything.

Dr. Mark received his Doctorate of Dental Medicine at The University of Pennsylvania, where he was elected as class president.

Dr. Mark is an ABO Board-Certified orthodontist, a distinction currently held by only about one in three orthodontists.

When he’s not in the clinic, Dr. Mark enjoys staying active through tennis and pickleball, or unwinding with a good book, a fishing rod, or time spent in the garden.

“Dr. Mark is an incredible orthodontist whose attention to patient care is unmatched. Orthodonture can be daunting, even as an adult, but Dr. Mark took the time to explain the process and treatment plan every step of the way. I almost wish I could get braces all over again just because the experience was so pleasant, but unfortunately, Dr. Mark's work is flawless and my teeth are straighter than ever. 5 stars!!!”

“Seeking orthodontics as an adult was a big decision for me but I feel well taken care of by Dr. Mark and the team. Everyone there is kind, patient, and efficient. Dr. Mark explains everything clearly and makes the whole process easy and stress-free. It’s early on but I’m so happy with my results so far. Glad I took the time to find the right doctor for me. Highly recommend!”
