Calandra Murray

Dental Hygienist
My name is Calandra; I usually go by Cally. I attended Middlesex Community College and have been practicing dental hygiene for 27 years. I love what I do and enjoy turning what may usually be an apprehensive experience into a relaxed, educated and friendly experience patients look forward to sticking with. I also enjoy helping patients to understand how their oral health and medical health are related, and love working with patients of all ages. In my spare time I enjoy spending time with my three grown children and my large family. I also enjoy doing volunteer work in my community.

Front Desk Administrator
My name is Christina.  Although I am new to the dental field I have over 10 years experience in the medical field. In 2009 I began working for a well respected family physician in Winchester as a medical secretary and medical assistant. During that time, I built a rapport with patients and I became passionate about the medical field.  In addition to having an outgoing and bubly personality, I am empathetic and find it rewarding to help others.
When I am not in the office, I volunteer in the community and spend my time with my family and friends.
I am excited for this new chapter of my career in the dental field with Dr. Ibrahim and his team!
