Diana M. Regan

November 15, 1970 ~ November 12, 2023 (age 52) 52 Years Old


Diana M. Regan, 52, of Bristol, passed away peacefully, surrounded by her loved ones on Sunday, November 12, 2023. She was born on November 15, 1970, in Bogota, Colombia, daughter of the late José and Dora (Vega) Sarmiento.

Diana was beautiful, incredibly strong, and had a generous heart. Her kindness shone brightly upon human beings and animals in equal measure. Her amazing sense of humor filled the 24 years of marriage to her devoted husband Timothy Regan with Love and laughter. Diana cherished her children Patrick and Danielle above all else. She earned a Doctorate in Veterinary Medicine in Colombia before coming to America, where she learned English, became a proud US citizen, and earned her nursing degree. She was universally admired by her patients and co-workers as a compassionate health care professional. Diana was also a talented cook, and accomplished gardener. Neighbors regularly stopped by to compliment her as she tended to her lovely Dahlias, while her cat Stella rolled in the grass nearby. Diana will be missed by her loving family, loyal friends, and coworkers, who are grateful for the time God gave us with her. She will live on in our hearts and be ever remembered for the Light she brought to our lives.

Besides her husband and children, Diana is survived by sister Sandra Ulicki and her husband Paul of Beacon Falls; brothers Nelson Sarmiemto of Colombia, Martin Sarmiemto of Germany, and her beloved nieces and nephews.
