Dr. Justin Yun

Dr. Justin Yun is as homegrown as they come. He was born, raised, and still lives right here in Ravenna, Ohio. Growing up Dr. Yun was a devoted soccer and baseball player. He played both sports in Ravenna and Rootstown, and many of his teammates have become lifelong friends.

Dr Yun didn’t always want to be a dentist. When he was younger, he dreamed of being a dairy farmer, just like his uncle. However, it was during his teens that Dr. Yun realized he had a passion for science and artistic talents. From there, his eyes turned toward dentistry and he has never looked back.

Dr. Yun graduated from Ravenna High School and went on to study Biochemistry at Kent State University. He earned his DMD from Case Western Reserve University in Cleveland, Ohio.

Dr. Yun lives in Ravenna with his wife, Rebeka (who was also born and raised in Ravenna), their two children, Avery and Elsie, and two family dogs, Maui and Kai. As your local Rootstown dentist, Dr. Yun is excited to bring his style and quality of dental care to this area he has known his entire life. Family has and always will be Dr. Yun’s top priority, and when you become his patient, you’ll be treated as a member of our own.

At Yunbelievable Smiles, you will never be just a “set of teeth” that is herded in and out. Looking for a compassionate, down-to-earth dentist in Rootstown? Come meet Dr. Yun!

Marsha Troyer

Dental Assistant

Marsha is known around the office as our “Drop Test Specialist.” She may randomly drop an instrument, or piece of equipment just to make sure it doesn’t break. She is great chairside, and amazing with kids. She is always in tune with the patients during their visit to make sure they are comfortable. Her favorite procedure to assist is extractions. Marsha has four kids. Outside of work her hands are full, her oldest boy (20) is in the Airforce, and she has two more boys at home (16 and 7), but of course her only daughter (4) runs the show.


Dental Assistant
Alissa grew up in Napa, CA. Her favorite thing about her job is helping patients feel at ease and being a part of their journey to a healthy, confident smile. Alissa has been married to her husband, Mark, for 10 years, and they have two daughters who keep them very busy. Their family also includes a yellow lab named Abby, a miniature pinscher named Minnie, and an orange tabby cat called Mr. Bojangles.


Office Manager
Rachel is originally from Texas and has been in Colorado Springs for the past two years. She started her dental career in Hawaii where she worked both the front and back office. Using her past experience as a dental assistant along with her knowledge of dental insurance, she is a great resource for our office when it comes to helping patients understand and maximize their benefits.
