Dr. Andrew Lasley didn't choose dentistry on a whim — he grew up in it. The son of a periodontist and the great-great-grandson of a dentist who practiced from the back of a horse and buggy, Dr. Lasley is a fourth-generation dental professional who understood from an early age what it means to build a life around helping people. Before becoming an orthodontist, he earned a degree in mechanical and biomedical engineering at the University of Vermont, completed his Doctorate of Dental Medicine at Boston University, and finished a three-year orthodontic residency at the University of Medicine and Dentistry of New Jersey (now Rutgers). That engineering foundation shapes everything about how he plans and approaches treatment — thinking not just about where teeth are today, but how every decision holds up over a lifetime.

Dr. Lasley has been practicing in Washington State since 2008 and is a recognized specialist through the Kois Center in Seattle, one of the most respected research-driven dental education institutions in the country — where he has been studying and returning every year for over 20 years. He is a Diamond Invisalign Provider, placing him among the most experienced Invisalign practitioners in the country, and regularly takes on complex cases that other providers turn away. His approach is rooted in early intervention, light-force treatment philosophy, and the kind of thorough treatment planning that considers the full picture of a patient's dental health — not just what's in front of him.

What drives Dr. Lasley, though, has always been simpler than credentials. His father taught him that the measure of a life is how much you helped others — and when his father passed, patients who had been with him for 30 and 40 years showed up in tears. That's the standard Dr. Lasley holds himself to every single day. He has turned down every offer to sell, stayed in the communities he serves, and built a practice where patients are treated like people he genuinely knows. Because they are.
