Derek Lamson Siegler

July 3, 1984 — April 29, 2024

Derek Lamson Siegler, a devoted husband, father, son, brother and friend passed away on April 29, 2024 from sudden heart failure. He was 39 years old.

Derek grew up in Brownsville, Vermont with his parents Cindy and Ted Siegler and brothers Nate and Devon. He graduated from Woodstock Union High and went on to attend University of Vermont, graduating with a degree in mechanical engineering in 2006.

A talented guitarist and songwriter, Derek spent years after college pursuing music and touring with his band at the time, Dr. Green. He enjoyed music in all its forms, whether it was recording solo in his studio, jamming with friends or performing live. In his career as a mechanical engineer, he was known as a specialist in the design of environmentally sound heating and cooling systems throughout New England.

Derek was a kind and compassionate person who was quick to smile and hugged fiercely. He was most at home walking in nature, skiing in the mountains, or swimming in rivers and lakes in all seasons of the year. He took joy in caring for other people, and would always show up for a day of skiing with a warm breakfast sandwich wrapped in foil for you.

 Derek met Cara Montgomery when they played on the same co-ed adult soccer team. After being friends for some time, and after many long chats sitting on the trunk of Derek’s old purple honda civic after games, they fell deeply in love. They married in 2015 and their son, Marlo, was born in 2017. Raising Marlo gave Derek more joy than anything, and being his dad was his greatest art form.

 Derek was always creating, writing, drawing, or painting. He loved doing art projects with Marlo, and they would spend hours making up stories and drawing characters for books or putting together a claymation short film.

 In addition to Cara and Marlo, Derek leaves behind his parents, Cindy and Ted Siegler of Brownsville, brothers Devon and Nate (wife Brooke), and nephews Jasper, Nash, and Jax. He also leaves his grandmother, Joan Lamson of New London, NH, his large extended family and many close friends.

 Losing Derek leaves an unspeakable void in the hearts of his family and many friends, which can only be softened by knowing the time they had with him was so beautiful. Derek would want you to honor him by taking a walk by the river or cooking some food for good friends.
