Thank you for choosing Dr. Tom Koustis!



Our office is conveniently located in Willoughby. We are just east of the intersection of Som Center Rd and Euclid Ave. The office started in 1992 in a tiny 2 chair office across the street. After 8 years we outgrew our office and moved to our current location.


Our office prides itself on treating every patient like they are a member of our family. We make every effort to make sure every patient understands their treatment options and fees.


We will prioritize treatment to try to maximize insurance benefits when possible.

We make every effort to treat patients painlessly by using Topical numbing before anesthetizing and make sure our patients are numb before treatment is started. For apprehensive patients we offer Nitrous Oxide

(Laughing Gas).


Our office can make 1 visit porcelain crowns by taking computer generated impressions, then milling the crowns while you wait. No need to put any impression materials in your mouth and no temporary crowns.

We accept; Cash, check, All major credit cards & Care Credit.

"You've been to the rest, now go to the best! I will never go to another dentist. Dr. Koustis and his staff are amazing. I completely trust them with my smile 100%!!! Give them a try and you won't regret it."

"We are new to your office, and wanted to thank you for the wonderful experience! Our children complimented you and your staff on how kind you all were. We are looking forward to seeing you next week."

“Thank you! Thank you! Thank you! You're the very best! You make going to the dentist fun...”

"Just had to write and tell you how happy you made me the first time I bit down to chew my food! After a few years now, struggling with an ill-fitting crown, an expert like you gets right in there to rearrange things back to normal. I can't thank you enough!
