Biography & Education

Dentistry is an exciting yet challenging field, but I truly enjoy every day of practice. Periodontics in particular is a fascinating field that is constantly changing and updating. New research and technology is changing the way periodontists treat patients, with increasing comfort and efficacy. And while I am passionate about saving teeth, dental implants have allowed for treatment not possible in the past and is an integral part of my practice.

Aliyah Shivji, DMD

Endodontist
Endodontist

Biography & Education

I’m Dr. Aliyah Shivji. Although I am Canadian and grew up in Edmonton Alberta, I attended dental school at Harvard School of Dental Medicine, where I fell in love with Massachusetts. After a residency program in New York, I decided to return to permanently move back to Massachusetts and am so happy to join the Great Hill Dental team! I enjoy painting, visiting museums, and even just walking around the area. There is no greater feeling than when someone tells you that you have taken away their pain. Taking away people’s pain with the work I do and helping them keep their teeth is what drew me to Endodontics, and makes my day, every day. My goal is to make the experience pleasant and worthwhile.

Biography & Education

I am deeply passionate about oral health and creating valuable services to people at a personal and community level. Practicing dentistry at Great Hill Dental has given me the opportunity to combine both of these interests in an environment that encourages clinical and ethical excellence.

The first step in providing quality oral care is creating an atmosphere of trust where patients can confidently express their concerns and get crucial information. There is a proven correlation between adequate preventative education and quality oral care and my goal as a clinician is to equip patients with such information, which in turn enables our dental team provide exemplary dental care. Finally, as dental technology evolves I strive to be in the forefront of dental innovation so that patients have access to improved levels of care.
