Orthodontic Associates of Southeastern Connecticut

I can’t say enough how much I enjoy working with OASECT. The staff is all so friendly and knowledgeable. The office is very welcoming and is always so clean. They treat their patients and each other so kindly. Delene is one of my favorites! She’s always makes a point to say hello at all my appointments and I love listening to her coach and encourage her newer teammates who are still learning. Having the option of both office locations is so helpful. I can’t wait to see my smile when everything is done!

Kind, professional and they do cute things like this along with free ice cream for the kids after their visits! We love Lyndsay Bayer, she was the best.

I love Dr. O’Leary at OASECT…. all the staff have always been so kind and welcoming!! My fourth daughter is currently starting treatment, and we have been extremely happy with the results. In fact, one of my daughters has enjoyed her experience so much she has been inspired to become an orthodontist when she grows up!

I cannot recommend Dr. O'Leary and his team enough! They've been absolutely fantastic in caring for both my son and daughter. Their expertise, kindness, and patience have made the entire orthodontic process a breeze. If you're looking for a top-notch orthodontist who truly cares about their patients, look no further.

As a 32 year old, going in to get braces was nerve wracking. However, everyone at OASECT was so kind and welcoming that I immediately felt way more calm about the process. Dr. Hack is an amazing orthodontist and I highly recommend him to anyone wanting to look into getting braces. He takes his time and answers all of your questions thoroughly. I really couldn't ask for better!

My experience with OASECT has been fantastic! From front desk, to back staff, to Dr. Hack, it is always a pleasant experience. I love my smile and I’m so grateful for everyone who helped along the way! Thank you OASECT!! You guys rock :)
