Lester James Hartman, MD

Dr. Lester James Hartman, known to many as Jim, passed away peacefully, surrounded by his family, on December 21, 2025, after living with Multiple System Atrophy. He was a devoted husband to Holly; a loving father to Sarah and Laura; a proud father-in-law to Erick and Andy; and a delighted grandfather to Mateo James, as well as to 4 grand-dogs. He was a cherished uncle to Annie, David, Matt, Kevin, and Alex, and great-uncle to Malachi, Addy, and Keegan. He was brother-in-law to Heather and Tim Warr. Lester was predeceased by his mother Zoe, his father Jim, his grand-nephew Kael, and his dogs Teddy and Buttons. Lester also leaves behind dear friends near and far, including those in New Orleans, Louisiana—where he grew up with great pride—and in and around Needham, Massachusetts, which he and Holly have called home since 1991.

Lester was a lifelong advocate for the underdog and for children’s health and wellbeing. At the age of six, after undergoing multiple surgeries on his club foot, he knew he wanted to become a doctor. Long recovery periods kept him isolated from peers, but they also sparked a deep love of science, nurtured through collections of shells, rocks, and minerals. A hyperactive child at a time before ADHD was understood, he was once told he would never graduate high school. He proved that prediction wrong many times over—graduating from Jesuit High School in New Orleans in 1976, St. Louis University in 1980, Louisiana State University Medical School in 1984, and later earning a Master of Public Health from the Harvard T.H. Chan School of Public Health in 2012.

In the mid-1980s, Lester moved to Massachusetts to begin his pediatric residency at Boston Children’s Hospital. Around that time, he met his wife Holly. Lester completed his residency at Boston City Hospital in 1987. He then joined Westwood Mansfield Pediatrics, where he practiced for decades and ultimately retired as senior partner in 2021. Lester’s passion for patient care—especially for children with special needs and their families—was unmistakable. He was known for his unconventional but effective health education: tucking his socks into his pants to raise awareness about Lyme disease, recording unrehearsed YouTube videos on everything from toddler behavior to home strep tests, and driving around with his car plastered in homemade anti-vaping bumper stickers. His antics and accidental use of CAPS LOCKS kept his colleagues on their toes. In his 50s, he took a sabbatical from clinical practice to study public health, igniting a new passion to protect children from the harms of tobacco and vaping. He became an active force in statewide efforts to raise the tobacco purchasing age to 21 in Massachusetts and to ban flavored nicotine products.

Lester was also committed to global health equity. He partnered with his cousins and a Haitian organization to expand access to healthcare in Juampas, Haiti, forging lifelong relationships through this work. As his understanding deepened, he also grappled openly with the ways racism and white saviorism can shape global health efforts.

While medicine was his vocation, Lester’s greatest joy was his family and the circle of friends who felt like family. He was a devoted husband and a loving father and uncle who encouraged curiosity, playfulness, and moral courage in his daughters. He was a caring son who took his father on bucket list adventures at the end of his life, being fortunate enough to fly his father over Antarctica and to the World Series. Together, he and Holly created a deeply welcoming home. Lester was a steady, unique presence as a father and uncle. He loved sending books to friends, family, and famous politicians or activists. Family vacations to Higgins Beach helped him to slow down. As his daughters grew up, he continued to be a supportive presence. He traveled to spend time with them from Los Angeles, California to Chiapas, Mexico.

The last few years of Lester’s life were difficult, as he slowly lost his independence and ability to communicate. His family was by his side throughout, and he was especially buoyed by his grand-puppies and by the arrival of his first grandchild, Mateo James, who turned one just before Lester’s passing. Lester’s family remains deeply grateful for the friends and family who showed up—especially after his diagnosis—through regular visits, phone or video calls, care, and love. His family knows now that how much he drove others bananas was only matched by how deeply he was loved. His legacy lives on in the countless patients he cared for, the policies he helped change, the questions he kept asking, and the people whose lives are better because he was in them.

A Memorial Service will be held on Saturday, January 31, 2026 at 11:00am at Christ Episcopal Church Needham, with options to attend in person and via https://www.facebook.com/share/182VpWXJcu/
