About Us

Meet the Doctors

David J. Ahearn, DDS

Dentist & Practice Owner


Dr. David Ahearn founded Perfect Smiles in 1993 and added our second location in 2010. With well over two decades of expertise in cosmetic dentistry and restorative dentistry, Dr. Ahearn regularly participates in continuing education to stay on top of the latest dental techniques and technologies – and so does the rest of the Perfect Smiles team. Together the team devotes more than 60-plus hours to continuing education every 90 days.

He also takes great satisfaction in helping fearful or apprehensive patients feel relaxed and comfortable through sedation dentistry. Unlike many general dentists, Perfect Smiles offers three kinds of sedation:

  • Inhaled sedation or “laughing gas”
  • Oral sedation
  • IV sedation

Cutting-edge technology – and its ability to improve the lives and health of his patients – is a passion for Dr. Ahearn, who has become a noted expert in the world of dentistry. He regularly teaches advanced programs across the country and is often a highlighted speaker at American Dental Association (ADA) events, where he shares his knowledge and love of dentistry with other doctors.

Dr. Ahearn is also the founder of Design Ergonomics, the leader of the field in high performance dental office design. With Dr. Ahearn being a leader in dental productivity, their dental office designs represent a highly integrated synthesis of current dental knowledge and technology.

“…Passionate About Helping Patients.”

Mary Jane Miranda, DMD



Dr. Mary Jane Miranda has been a member of the Perfect Smiles family since she was a child, when her mother worked at Perfect Smiles. At an early age, she expressed an interest in dentistry and her interest grew through the years as she came to the office with her mom and saw Dr. Ahearn and other dentists at work. After graduating from high school, she started working at our front desk and soon after became a certified dental assistant.

In 2007 she graduated from Rhode Island College and took a hiatus from the practice to attend Tufts University School of Dental Medicine. She was so committed to becoming a dentist that she commuted to Boston from Somerset, MA every day for four years! After obtaining her degree, Dr. Miranda returned to practice dentistry where she first fell in love with the profession – at Perfect Smiles!

Dr. Miranda serves as an advisor to the Dental Assisting Program at Diman Regional Vocational Technical High School where she helps steer the vocational program and students toward future success. Her involvement helps keep the dental program up-to-date, and she enjoys serving with students she has mentored over the years.

Our team values the commitment Dr. Miranda has to educate and advance our team members skills, and her direct approach in creating an educating and positive experience for her patients.

During her spare time she enjoys gardening and spending time with her spouse Adam, and their two children James and Jane.

“I have wanted to be a dentist since I was in the 4th grade. I really love treating patients like family.”

Dan Tracy, DDS



Dr. Dan Tracy joined the Perfect Smiles team after graduating from Columbia University College of Dental Medicine followed by a general practice residency at the University of California, San Francisco.

He has since discovered that cosmetic dental procedures are his favorite because he can positively transform so many aspects of his patient’s life by giving or enhancing their smile.

Dr. Tracy’s enthusiasm about dentistry quickly puts patients at ease and he always looks forward to helping patients smile confidently!

We would say the qualities that describe Dr. Tracy are: genuine, selfless, caring, and thoughtful. He is an amazing and inspirational person for all who know him. We are honored to have him on our team and proud of his dedication to the field.

He has spent many years volunteering at community events and mission trips overseas along with the Perfect Smiles team. During his free time, he enjoys watching Boston sports teams and cooking.

“I love helping patients be able to smile confidently!”

Madhuri Patel, DDS



Dr. Madhuri Patel is a skilled, likable, and empathetic dentist. Patients love her because she provides excellent dental care in a gentle and relaxed manner. With a passion for family dentistry, she recently moved to Rhode Island from New York City after completing her dental school at the largest and busiest dental school in the U.S., NYU College of Dentistry. Her coworkers and our patients appreciate her commitment to her work and the well-being of her patients. She always carries a positive attitude along with a calm demeanor.

During her free time, she enjoys traveling, hiking, and volunteering at community events and dental mission trips.
