Lisa Marie Dore, 46, of Merrimack, NH, passed away peacefully on Sunday, October 26, 2025, at Southern NH Medical Center in Nashua, after a courageous battle with cancer.

She was born in Boston, MA, on September 3, 1979, the beloved daughter of Daniel and the late Patricia (Manzo) Rivera. Raised in Wilmington, Lisa graduated from Shawsheen Valley School of Practical Nursing and later earned her RN from St. Joseph School of Nursing. Most recently, she proudly completed her Master's in Business Administration with a focus on Healthcare Management from Southern New Hampshire University, an incredible achievement she reached this past year while undergoing treatment.

Lisa dedicated her career to caring for others as a Registered Nurse and had been proudly serving with Interim Healthcare for the past 16 years. Her compassion, dedication, and kindness touched the lives of countless patients and families.

Beyond her professional life, Lisa found joy in the simple things. A true Disney fanatic, some of her happiest memories were made on magical trips with her family. She loved her pets, exploring new crafts, crocheting cozy and fun creations, and spending quiet time reading. Deeply committed to her health and wellness, Lisa approached every challenge in life with determination and grace. A fighter since the day she was born 3 months premature at just 1 lb 14 oz, she faced life's ups and downs with strength, courage, and an unwavering optimism that inspired everyone around her.

Lisa is survived by and will be forever loved and remembered by her father and mother, Daniel and Bobbi Rivera; her two daughters, Mikayla Dore and Ava Harrison; her partner, Mike Harrison; her siblings, Michael Cardello and Kristen and her husband Bobby Chartier; her grandmother Corrine Manzo; her grandfather John Mastrangelo; several aunts, uncles, cousins, nieces and nephews; as well as extended family members and dear friends.

As her loved one's picture Lisa now, they find comfort in knowing she has found peace "somewhere over the rainbow".  Her light, love, and kindness will live on in the hearts of all who knew her.

Visitation will be held on Saturday, November 1, 2025, from 10:00 AM to 12:00 Noon at Rivet Funeral Home, 425 Daniel Webster Highway, Merrimack, NH. A service celebrating Lisa's life will follow at 12:00 Noon in the funeral home chapel.
