“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.”

  • I came into the office with a problem and as usual, it was handled very professionally by the entire staff. Dr Armento is always very calming and thorough. He explained the problem and gave me the solution. I will have a follow up appointment. My family and myself have been going to the Doctor for at least the last 11 years. We are very satisfied with the professionalism and efficiency of the Doctor and his staff.
