Erin Sweeney DDS PLLC
For Dr. Sweeney, a Kois Center Dentist, dentistry has always been where science meets art — a space to blend precision with creativity and transform something functional into something beautiful. What she’s discovered along the way is that while perfecting a smile is deeply rewarding, getting to know the person behind it is what truly inspires her. Believing that patients in Western New York deserve the same caliber of care found in cities like New York or Los Angeles, Dr. Sweeney has dedicated her career to continuous growth and education. She has completed over 400 hours of advanced training, is a trainee at the Kois Center in Seattle, and is pursuing accreditation with the American Academy of Cosmetic Dentistry. She is also a proud member of the American Dental Association, New York State Dental Association, and the 8th District Dental Society. Dr. Sweeney approaches each patient relationship with intention and empathy, taking time to listen and understand what truly matters to them. Her meticulous attention to detail ensures that every treatment reflects not only clinical excellence but also her patient’s individuality — a smile that feels natural, confident, and entirely their own. Outside the practice, Dr. Sweeney finds joy in the simple things: spending time with her golden retriever, Paul, and her fiancé, Albert, discovering new live music, getting lost in a great book, and cheering on the Buffalo Bills — always proud to call Western New York home.
