Smile Design Associates

Smile Design Associates 610-363-0307 Call & Schedule Today! We at Smile Design Associates are dedicated to helping our patients be the best they can be.

Your dental health is our primary focus while providing excellent service in a comfortable, trusting environment. We are a group of caring professionals that have been working together for many years, making us a great team to provide the best care for your family. The practice was founded by Dr. Mackey in 1996 in a 650 sq ft space in Chester Springs. Our practice had expanded greatly since then,

all thanks to our loyal patients who have recommended us to family and friends. The practice has grown so much we needed to move to our current 3000sq ft facility in the Lionville Professional Center. As more and more people shared their experiences with friends, neighbors and coworkers we wanted to elevate our level of care by adding Expanded Function Dental Assistants, licensed in Pennsylvania, to help the doctors perform more specialized functions chairside. All of our team members are certified by the American Heart Association in CPR basic life support and trained to use the AED Defibrillator machine in our office. The assistants and hygienists as well as the doctors are retrained annually in infection control techniques and radiology. In addition, they regularly advance their skills through continuing education classes in various areas of dentistry. Dr. Mackey attends the American Dental Association Annual Session every year as well as numerous hours of continuing education courses annually. Dr. Mackey is a member of the American Dental Association, Pennsylvania Dental Association, and Chester Delaware County Dental Society.
