A celebration of Tiana’s life will take place at the First Unitarian Universalist Society of Burlington on Friday, August 29th at 4 pm.
In lieu of flowers, please consider honoring Tiana’s memory by visiting your local animal shelter and adopting a cat in her name or making a donation to From Feral to Fur-Ever Rescue (49 Pine Street, Swanton, VT 05488), a rescue organization close to Tiana’s heart. Nothing would have made Tiana smile more than knowing a cat had found a safe and loving home.
Tiana (“TT”) Regina Roussin, beloved partner of Luke Clavelle and loving mother of Ryley Roussin, passed away unexpectedly at the University of Vermont Medical Center on August 22nd. Tiana, only 32 years old, suffered from postpartum hemorrhaging. The only bright moment on a very dark day was the birth of Clara Ferries Clavelle, the beautiful and healthy daughter of Tiana and Luke.
Tiana was a remarkable and resilient woman. As a young single mother, she was fiercely protective and a force to behold. Tiana raised her daughter Ryley, now 13, with love, laughter, affection, and friendship.
Anyone who knew Tiana looked forward to spending time with her. Her beautiful smile and effervescent laughter came easily, and those vibrant blue eyes lit up any room that she graced. Her spirit and energy were infectious and she always left you wanting more time with her.
Tiana’s creative talents included drawing, painting, music, singing, comedy, playing cribbage and Wordle. She was a lover of aquariums and animals. She particularly loved her cats, Nova and Beans (most of the time). Tiana loved hiking and was always up for an adventure. With Luke, she found a love for travel and had only just begun to explore the world.
Tiana graduated with honors from Milton High School in 2010 and pursued Higher Education at Emmanuel College in Boston and Community College of Vermont. She worked her way up the ranks in the hospitality industry before moving on to become a Commercial Lines Customer Service Representative at Cheeseman Insurance. In March of 2024, Tiana proudly joined Acrisure as a Commercial Lines Account Manager.
In addition to Luke, Ryley, and Clara; Tiana is survived by her parents, Leslie and Jeff Thayer, siblings Trista Roussin (her twin and first soulmate), Jenni Roussin and her fiancé Dimitrius Palmer, Lillian Thayer, Nicholas Roussin and his wife Kate, Jamie Roussin, and Ethan Roussin. Tiana is also survived by her adoring Roussin uncles and aunts, Paul, Lynda, David, and Anne.
Along with her family, Tiana will be forever missed by her extended family: Peter Clavelle and Betsy Ferries who loved Tiana like their own daughter and honorary siblings; Jae Clavelle and her husband, Zac Araujo and Will Clavelle and his wife, Anne Culp. It is impossible to capture all the names of the friends who loved her like a sister from grade school on. We mourn as one.
Tiana had a remarkable way of making people feel seen, valued, and loved. Whether it was through a warm hug, a compliment, or a presence in times of need, she reminded us that love should never be left unspoken. And so, in honoring Tiana’s memory, let’s carry that forward. Let’s tell our people we love them. Let’s not leave anything unsaid.
We thank the doctors, nurses and staff at UVM MC.
