"My first visit to a dentist in two years, and I was beginning to get nervous about finding a dentist I had never used. Thankfully, a neighbor recommended Mount Vernon Smile Design. I am 80, so I spend a bit of time in various medical facilities, and it becomes evident to me when a medical organization has succeeded in building a team of care givers and staff having the competencies and attitudes to help their patients. This small Mount Vernon dental office has really figured it out. I met a half dozen staff members who each introduced themselves telling me their names and what their role was in my exam. They each were familiar with a Pre-visit Questionnaire I completed, and they were familiar with my health and medical/dental history. They were all competent, courteous, gentle, professional and KIND."

"My family and I recently switched over from another dentist to Mount Vernon Smile Design and couldn’t be happier! The staff is super friendly and helpful, they were fantastic with my two children, and I really appreciated that Dr. Nick interacted with my kids and explained things in a way they could understand. I went in for a couple week later and met Dr. Whitney who was also great! If you’re looking for a new dentist, we highly recommend this practice."
- Joshua
"The team of caring people at Smile Design went above and beyond with my mom. She’s in a wheel chair and they moved her into the dentist chair to do a better cleaning. They were so kind and gentle with her and gave me some good tips on how to communicate the need for better dental care to the staff where she lives. Thank you to Elizabeth and Dr. Nic!"

"When you enter Mt. Vernon Smile Design you will immediately feel welcomed into the "family". The camaraderie between the doctors and staff is exactly what I look for in a dentist office, as it is passed on to their patients. My level of anxiety completely disappears after Dr. Forsyth's ease, kindness and expertise walk me through each procedure. In addition, Mt. Vernon Smile Design's up to date equipment is less invasive with faster results that contributes to further relief and calmness. Because of their inclusive and caring attitude, and Dr. Forsyth's first-rate mode of practice, I look forward to my visits knowing my oral wellness and well being are a priority!

"After 4 years of not being in a dentist office I was very scared to be back but everyone made me feel so welcomed! I am so happy I chose to come here, Elizabeth, my dental hygienist was very sweet and made sure I felt comfortable the entire time. Dr. Whitney is a sweet heart! Such a pleasant and kind environment to be in. I will definitely be recommending them to my friends and family!"

"I highly recommend Nicholas "Dr. Nick" Forsythe, DMD and his team of dental professionals to everyone who is seeking the best place to go for your dental needs. I was put at ease right away. I was not nervous or anxious. I was provided with options and advice that may save my life. They really care about their patients. They are friendly and personable. They are experienced in utilizing State-of-the-Art equipment. It was an amazing experience. Please put your dental fears away and put yourself in their care - because they really care!!!"
- Lora
"I have never been to such a kind, professional and caring dentist office. Their yearly plan is affordable without insurance and worth every penny. Every concern I had from previous heavy handed and scary dentist experiences were addressed completely and very delicately handled by Dr. Nick. I appreciate the constant reassurance and judgement free approach this office gives its patients. Also the timely manner I was able to get in for a root canal and have my pain addressed and treated within the week I called was very much appreciated! Thank you so much!"
- Nikole
"This was my first time visiting this office, and I’m so glad I chose them. From the moment I walked in, the staff made me feel welcome. The dentist took the time to explain everything clearly and made sure I was comfortable throughout the visit. The whole experience was smooth, and professional. I feel confident moving forward with them for my dental care and highly recommend this team to anyone looking for a dentist."
