Meet Our Staff

Dr. Minna Kim joined our staff in June 2017 with over 22 years of experience in cosmetic, implant restorative, and family dentistry. She is highly skilled in all phases of dental care, including Invisalign and oral surgery, which has made our practice even more comprehensive. Dr. Kim is a terrific clinician who brings professionalism, precision, and warmth to every patient interaction. We’re proud to have her as a part of our dental care team.                       

Keri is a graduate of St. Bernard’s High School and earned her RDH degree from the University of New England in Biddeford. She met Dr. Cronin over twenty-five years ago when they worked at another office together. He knew then that she would be his first hygienist hire — and in 1995, she officially joined Cronin Dental. Keri is excellent with patients and always prioritizes their comfort and concerns. She and her husband Chris enjoy spending time with their grown children, grandchildren, and relaxing weekends at Oak Hill Country Club.

Annie joined our team in May 2014. She graduated from Rockport High School in 2009 and earned her RDH degree from the Massachusetts College of Pharmacy in 2011. Dr. Cronin first met Annie in 2012 and was impressed by her energy and personality. When a full-time position opened a year later, he reached out, and Annie became a valued part of our office. Annie is a warm, mature, and dedicated professional. Outside the office, she and her husband Matt enjoy time with their three children.

Marianne is a Registered Dental Hygienist who joined our team in the fall of 2015. Raised in Leominster, she graduated from St. Bernard’s High School in 1998. From 1999 to 2013, she worked as the Lead Pharmacy Technician at the CVS on Nelson Street in Leominster. Seeking a new path, she enrolled at Mount Wachusett College and earned her RDH degree in May 2015. Marianne is an excellent clinician and a compassionate professional. She’s a natural leader who tailors each treatment plan to the individual needs of her patients. Marianne and her husband Matt enjoy spending time with their daughter and son and still live locally.

Trinh Trieu works full-time primarily as a Dental Assistant, while also assisting at the front desk and in instrument sterilization. Born in Vietnam, Trinh moved to the United States in 1987. Despite having limited English at the time, she worked diligently and graduated from Montachusett Technical in 1993 with a degree in Dental Assisting. Her high school instructor once said she was the best student she ever had. Trinh has been with Dr. Cronin since 1995 and is known for her exceptional clinical skills and strong work ethic—despite Dr. Cronin’s daily teasing! She and her husband Khuong enjoy supporting their daughters in track, basketball, soccer, and martial arts.

Erika is a Registered Dental Hygienist who first joined our office as a temporary team member while Annie was on maternity leave. She was such a great fit that we invited her to stay on one day a week—now, she’s full-time! Erika is a graduate of Burlington High School and a proud mom of two. She courageously returned to school while raising her children and earned her RDH degree from Mount Wachusett Community College in 2015. Erika is a warm, outgoing presence in the office who loves country music, cheering on the Patriots, and spending time with her husband Justin and their six children (yes, six!).

Katie is a Registered Dental Hygienist who first joined us as a temporary team member. She quickly became a favorite among patients and staff alike, and we were thrilled to find a way to keep her on permanently. A 2007 graduate of Mount Wachusett Community College, Katie spent 12 years working in Belmont before moving her career closer to home in Leominster—a better fit for her growing family and busy schedule. She has a quick sense of humor, loves a wide range of music, and truly enjoys the camaraderie of the dental office. Outside of work, Katie keeps busy cheering on her children at baseball, football, and basketball games.
