Trina Janet Tinglum, 58, of Madison, died on March 22, 2021 in New York City, after a brief but fierce battle with cancer. Trina was born on September 4, 1962, in Merrill, WI. She attended elementary school and high school in Madison. She earned a law degree from the UW Law School, and a Masters degree in Library and Information Science from UW-Milwaukee. Her career was dedicated to teaching the art and craft of legal research and writing. She worked as an editor at West Publishing (later Thomson Reuters) and taught at the University of St. Thomas and Hamline University in St. Paul, MN. In 2012, she joined the faculty of the Legal Research and Writing Program at the UW Law School. Trina adored her students and dedicated herself to their professional development and their personal well-being.

Trina was a proud mom to Georgia Schmitt, 26, and Gunnar Streitz, 11, and a longtime partner with Jay Streitz. She was a passionate triathlon competitor for many years, and a devoted runner and swimmer. She loved her daily walks with the family dog, Balto. She avidly consumed news of, and humorous commentary on, current events and politics. She was a fierce advocate for a variety of causes, most notably women's equality and reproductive rights. She loved celebrity gossip, Twitter, and the New Yorker. She could make almost anyone laugh out loud. She had a beautiful sense of style. She made the world's best brownies. She loved dogs and cats like family, always extended a hand to people who were struggling, and naturally created an accepting and judgment-free space for anyone who sought her help.

Trina was preceded in death by her father, Sverre Tinglum. She is survived by her partner, Jay; her children, Georgia and Gunnar; her mom Georgia Cook; her sisters, Britt Tinglum and Kirsten Friedman; her niece Sverre LeRoy and nephew Per LeRoy. She is survived by two beloved aunties and many adored cousins. Also surviving her are her dog and soulmate Balto, and her cat, Girlfriend.
