My experience with Dr. Flanagan and his staff has been an exemplary experience. Most dread going to a dentist, this outfit will change your... mind.Lauri Cox is the face of this company. She worked with me through a very difficult time in my life. (I got hit by a semi on my motorcycle).The year of recovery delayed my getting Invisiline. She reassured me that when I was ready they would be there for me. Lauri guided me through the financial aspect of getting invisiline in a way that worked for my situation. I can attest that all of Dr. Flanagan's staff are very helpful and professional now that I am wearing my first retainer. I am very grateful to Lauri and Dr. Flanagan's team.read more

Our experience with Dr. Flanagan has been outstanding. The office is run like a well oiled machine. We have been seen on time for all of our... appointments! The customer service in all areas is fantastic. When my daughter's appointment was cancelled due to COVID-19, Dr. Flanagan made arrangements to personally give me her liners so she could continue her treatment. From the bottom of my heart, thank you Dr. Flanagan!read more

I am forever grateful for Flanagan Orthodontics and the work that they have done to my mouth. As a younger patient, I did not want braces at all, but... my parents insisted. Now, as a soon to be 21 year old, I could not be more thankful for the smile that I have. One of the first things that strangers say to me, is how beautiful my smile is. The staff is beyond friendly and patient, and you can tell they genuinely care about their clients! I would recommend Dr. Flanagan over and over again!read more

My husband and I both decided to do Invisalign together at Dr. Flanagan’s office and it was a really great experience. The process itself was... relatively painless. Neither of us experienced a lot of soreness throughout the process. We were always able to make appointments that fit into our schedule and we had less office visits than with traditional braces. We both work full time and we have two small children, so this was important to us. The staff was very welcoming and friendly. They were quick to respond to questions we had and accommodate our needs. We enjoyed working with them. We are also very happy with the results of our smiles!read more

Kind, professional; clean. Cutting edge techniques and fantastic service from start to finish.

Willing to work with your financial situation to find the payment plan that works for your budget. An all around fabulous place to choose for orthodontics!read more
