Cari

Dental Hygienist

I help patients develop and maintain good oral health through regular cleanings, checkups, and preventive care. I have worked with Dr. Portnoff since she came to the practice and have more than 25 years of experience working throughout the dental field. I enjoy educating our patients on how they can improve their dental health and I love seeing the progress they’ve made when they come back for checkups.

I have three children: two daughters and a son. When I’m at home, I love to cook and entertain. I play tennis a few times each week and enjoy working out at the gym. I have been fortunate enough to do some traveling and enjoy the warm weather.

Marylou

Dental Assistant

I work alongside Dr. Portnoff to ensure patient comfort and efficiency during procedures, as well as maintain our high standard of care. I joined Dr. Portnoff and her team in October 2012 and have been working in dentistry and orthodontics for more than 25 years. I love getting to know our patients and teaching them about all the great technology we have to offer. Our team is very supportive of each other and we like to have fun!

I live in Hopkinton where I grew up, with my husband and our three wonderful children. I live on the land my grandfather once lived on.  We call it the “family compound,” because my whole family lives there. I love it! I also love watching baseball and hockey, spending time with my family, and traveling when we can.

Lauren

Dental Assistant/Patient Care Coordinator

As a longtime dental assistant, I've recently transitioned to more of an office role.  Having the clinical experience I do, I feel as though I am able to help patients with understanding the procedure they are having from both a scheduling and clinical standpoint.

I've worked with Dr. Portnoff and team since 2011.  I love the high standard of patient care we have dedicated ourselves to in this office. We take time with every patient to ensure their comfort both in the treatment rooms and at the end of their appointments while checking out is maintained.

My husband and I try to get to every soccer game our daughter plays in while she is attending college.  I live on a farm, and have plenty of animals that keep me busy while not at work.  My family enjoys to travel, and our favorite destination is Walt Disney World.

I joined the Cornerstone Dental team along with Dr. Colleen Lynch's office where I had worked as office manager for almost 20 years, in March of 2016.  This transition to a larger practice has been a new adventure in my life. To be part of this team is exciting, and I continue to grow from this experience. 

It gives me great pleasure to see the patients of Dr. Lynch's office follow us to our new location.  I truly treasure many of the wonderful relationships with many families and look forward to forming many new relationships as well.
