Michael J. Armento, DMD

“I always wanted to help people. Plus I really love children and I wanted to make sure that they like going to the dentist for a lifetime of good oral hygiene. I also like to teach people and explain as much as I can about dentistry so that they are well-informed as to why it is important to keep a healthy mouth. Educating my patients is very important to me.

My dad is a retired orthodontist, and I have two brothers and two sisters-in-law who are all dentists, so I have been around dentistry my whole life. I always wanted to change the misconceptions about dentists and dentistry. I wanted to help my patients enjoy coming, and make them feel relaxed and comfortable.

I enjoy my patients and constantly meeting new people. I enjoy helping someone who used to hate to smile to enjoy their smile, and seeing their personality change. I also enjoy working in the same town where I live. I try to explain as much as I can about every procedure or condition. I am also very calm, understanding and easygoing. We want to create smiles and relationships to last a lifetime.

I hope to make my patients feel very comfortable in the office, and that they feel like part of our family. I want them to know that I am always here for them, and that they can reach me any time with any of their needs. I really enjoy getting to know my patients and taking a personal interest in their lives. When my patients tell me they enjoy coming to see me, I know I’ve done my job.”
