Dr. Thomas McKenny has been recognized as one of Seattle Met’s Top Dentists for the past 15 years—a reflection of his dedication to clinical excellence, patient-centered care, and a reputation built on trust.

You deserve a beautiful smile

We believe that exceptional dental care is about more than just skills and technology (though we’re proud of those too). It’s about creating a space where patients feel comfortable, respected, and confident in the care they receive.

We're proud to serve the greater Seattle area and even prouder to say that our vision is simple: to offer more personal and exceptional care than anyone else. Every patient who walks through our door deserves that—and we show up every day to deliver it.

What Kind of Training Does a Dentist Have?

Becoming a dentist isn't just about learning how to fix teeth-it's about mastering a blend of science, art, and people skills. The journey starts with earning a bachelor's degree, usually focused on sciences like biology or chemistry, which lays the foundation for understanding the human body. Then comes dental school, an intense four-year program where students dive into everything from anatomy and oral health to hands-on training with real patients. It's like boot camp for your smile's best advocate, combining book smarts with practical skills to ensure dentists can handle any situation, from routine cleaning to a tricky root canal.

But the training doesn't stop there. Many dentists pursue additional specialties, like orthodontics or oral surgery, which can add several years of rigorous education and clinical practice. Even general dentists constantly keep their skills sharp with continuing education, staying updated on the latest techniques and technologies. Think of it like a never-ending quest to be the best at what they do. So, when you sit in that chair, you're not just getting care from someone who "knows teeth"-you're trusting an expert who's spent years perfecting their craft to give you the healthiest, brightest smile possible.
