Get To Know Dr. Mary Keezel

I was born and raised in Cape Coral in southwest Florida. At the age of 5, I was first introduced to the idea of being a dentist. I watched the classic Christmas animated movie, Rudolph, and I instantly felt a connection with the character Hermey. Hermey was an elf who wanted to be a dentist. Apparently, I was an extremely impressionable child because I just knew that I wanted to become a dentist by the end of the movie. Fast forward to 10 years later. After completing my own orthodontic treatment, I decided to see if dentistry was really for me. I began shadowing different professions including multiple dentists. It was during this time that I met an orthodontist who became my mentor and has been one of my biggest supporters throughout my journey. I attended Florida State University (Go Noles!) where I received my Bachelors of Science in Exercise Science. I then decided to move up north to Boston, Massachusetts where I lived for four years while I earned my dental degree from Tufts University School of Dental Medicine. I absolutely loved having actual seasons every year, but the big city lifestyle wasn’t for me. When it came time to move again, I was excited to return to Florida and call Jacksonville my new home. I completed my orthodontic residency at Jacksonville University School of Orthodontics, where I met the love of my life, Dr. Andrew Mancia. We are excitedly planning our wedding which is coming up soon in March of 2022. In my free time I enjoy watching/playing soccer, snowboarding, spending time with family and friends, and trying new things. I am currently trying to learn how to surf in my spare time!

I am extremely excited to have joined the Coastline Orthodontics family, and I am enjoying getting to know all our amazing patients! I am so grateful to be a part of your orthodontic journey and I look forward to seeing you in our office!
