Green Lake Orthodontics

Dr. Cassidy is easily the best orthodontist I've ever worked with (I've worked with a few over the years). My kiddo is getting close to finishing their treatment. Dr. Cassidy is great with kids and parents/caregivers, has high standards for how she wants her clients' teeth to look, has a ton of patience, is professional but easy to work with, and her staff are excellent. I highly recommend GLO with zero reservations. You will be glad you chose GLO.

Greenlake Orthodontics was outstanding from start to finish. The team was highly skilled, kind, professional, and consistently made me feel comfortable before and during the entire process. Every step was clearly explained, expectations were set well, and everything proceeded in a calm, low-drama way that I really appreciated. What stood out most was their quiet excellence — they simply do things really well without unnecessary fuss. Scheduling, communication, and logistics were all smooth and easy. The whole experience felt thoughtful, organized, and reassuring. Easy to recommend.

I had such a wonderful experience with Dr. Cassidy and her team! The office is beautiful, clean, welcoming, and every single staff member is incredibly friendly and professional. I always felt well cared for throughout my treatment, and am so impressed with Dr. Cassidy. I highly recommend GLO — truly the best experience you could ask for from start to finish!

Green Lake Orthodontics situated in Seattle is a hospitable medical environment that is positioned to offer the best reception and care as it is in an environmentally friendly area and has state of the art infrastructure both within and outside its premise.

Whole office rocks. Very efficient with scheduling,communicating. and getting the treatment done. They did an excellent job and I couldn't recommend it more

I had an incredible experience with Green Lake Orthodontics (GLO) and Dr. Sara Cassidy. As an adult going through Invisalign treatment, I was amazed at how seamless the entire process was. I truly couldn’t be happier with my results—I now have a fabulous smile and healthy teeth that will last me well into the future. Dr. Cassidy is friendly, welcoming, professional, and extremely knowledgeable. Every staff member I interacted with was equally professional and a pleasure to work with. The treatment was turnkey and efficient—maintenace scans were done at home, which meant I needed very few in-person appointments. Despite that, the team was always highly responsive and attentive to any questions or concerns I had along the way. I cannot recommend Dr. Cassidy and the GLO team enough. If you’re considering orthodontic treatment, this is the place to go.

If you want high quality care with an exceptional team in a beautiful office, you’ll find it all here! It’s clear that this team is very skilled and genuinely care about their patients. Lauren, Kailenne, Alyssa and Dr. Cassidy have all been so welcoming and comforting throughout the process. This is truly the best of the best!
