Dr. Wonkyu Seo

  • Away from dentistry, Dr. Seo enjoys watching sports and rooting for the LA Dodgers and LA Rams.

Dr. Wonkyu Seo’s journey in dentistry began when he attended Rockhurst University in Kansas City, MO. He completed his doctorate in dental at New York University’s College of Dentistry in New York City — a school ranked #5 on SCImago Institutions Rankings’ of dental schools in the country.

Once he had the necessary tools and education under his belt, he began practicing as a general dentist in 2018. Throughout this career, Dr. Seo has placed making patients feel like family as his top priority. By creating special bonds, Dr. Seo can better diagnose and treat patients while giving you the advice you need for success.

Dr. Seo is a sports fanatic, particularly cheering for the LA Rams and LA Dodgers, though he’s never been a resident of the area. Sports and his dental career don’t compare to his love for his wife, though, whom he spends a great deal of time with when he’s not practicing dentistry. We can’t forget to mention the joy he gets when spending time with his Maltese pooch, Doobu!

"What an incredible experience! I came into to Summer Dental to see if they could fix my permanent crown that repeatedly fell out only days after installation by my old dentist. They instantly knew what to do, and a few days later, they reworked what was left from my old tooth and installed a brand new crown.
This is a huge thank you to Dr. Seo. I can now sleep easily knowing that I have a competent dentist. THANKS!"

Dr. Peter Bonifatto grew up in Vegas in the Summerlin area and noticed as a child that a smile has a profound effect on people. He completed his undergraduate and dental school education at the University of Nevada, Las Vegas campus, and studied abroad in Brighton, England, for one year. Interestingly, he originally wanted to become a plastic surgeon but learned it wasn’t for him while in college.

Upon earning his doctorate, Dr. Bonifatto moved to Hollywood, CA to pursue his dental career. During this time, he cultivated his skill and expertise. He’s now back in the Vegas area (you can’t take Vegas out of the man), practicing at Summer Dental and seeing the meaningful impact dentistry has on people’s confidence and general health.

Outside these doors, Dr. Bonifatto loves to cook and experiment with new recipes, though you’ll never catch him baking. He willingly admits his baking skills, or lack thereof, aren’t great.

And they’ve made my teeth and smile look so much better than anywhere else I’ve been. They also have long hours where availability is never a problem. State of the art equipment also. I appreciate what they’ve done for my smile. Thank you!"

Dr. Momtaz smilling

Dr. Pouya Momtaz

Orthodontist - Las Vegas, NV.

  • Dr. Pouya Momtaz has always desired to help people through building close relationships and bettering their lives.
  • For his fellowship, he decided to move across the country to Las Vegas. He’s enjoyed it so much that he’s decided to practice here.
  • Dr. Momtaz is an outdoorsman and a family guy. He loves to work out and enjoys the company of his friends.

Dr. Pouya Momtaz grew up in Boston, MA. He was the middle child, with two sisters. He desired to help people, build relationships with them, and be along for the ride of smile transformations, thus choosing orthodontics. It helped that his father, whom he looked up to, was also a practitioner. He completed his undergraduate and dental school degrees and a one-year residency in Boston.

Making a daring move, he decided to pack his bags and move to Vegas. Before practicing as an orthodontist here, Dr. Pouya Momtaz completed a one-year fellowship in orthodontics and dentofacial orthopedics and an orthodontic residency at the University of Nevada in Las Vegas.

After getting a taste of the area, Dr. Momtaz chose to stay here to practice. Today, he’s now watching patients’ journeys, from start to finish, when transforming their smiles, and he loves every minute. In his free time, he’s outside grilling, playing basketball, or working on his Jeep, the while surrounding himself with family and friends.

"This honestly is the only dentist I will go too. I have never been to a kinder dentist! I saw Dr. Chen for a root canal and Dr. Seo for prepping a bridge and both were very easy experiences. They were very kind with my needs because with my autism. Completely painless and easy experiences."
