Anne Chatellier

Baton Rouge, LA - I have fought the good fight, I have finished the race, I have kept the faith. - 2 Timothy 4:7.

Anne Marie "Annie" Pellecchia Chatellier peacefully transitioned from this life and her six-year journey with ALS and entered her eternal home on March 23, 2021, surrounded by her family. Born March 3, 1964 in Portsmouth, VA, Annie's family moved to Baton Rouge, LA in 1968 where she resided until her passing. She attended St. Thomas More Catholic School where she made life-long friends. Annie also attended Broadmoor High School and LSU. She found her passion in nursing. She obtained her Associates Degree in Nursing from Our Lady of the Lake College in 1999 where she was awarded the Louisiana Student Nurses Association Academic Scholarship (1998) and named the Dr. John Beven Valedictorian for Nursing (1999). Annie would go on to pursue a diverse and rewarding career first at Women's Hospital and Women's Center for Fertility, then Pennington Biomedical Research Center, The Baton Rouge Clinic, and finally, Our Lady of the Lake Hospital, Franciscan Mission of Our Lady Health System (FMOL). Although she faced great physical challenges related to the progression of ALS, through the use of advanced technologies and the unwavering support of her FMOL family, she was able to continue working, contributing, and mentoring from home until just shortly before her death. After being diagnosed with ALS, Annie began to seek ways to ensure a better future for herself as well as all others facing the disease. She was a passionate advocate and fundraiser for the ALS Association, and she served on the Board of the local Louisiana/Mississippi Chapter. Her "Walk to Defeat ALS" team, "Annie's Angels", supported those efforts by holding fundraising activities over the course of several years. In 2016, Annie was named the recipient of "The Iron Horse Award" honoring her many contributions to the ALS community and the grace with which she chose to "live with ALS". One of her greatest accomplishments was championing the creation of a mutli-disciplinary clinic for ALS patients at Our Lady of the Lake in Baton Rouge. Annie worked tirelessly with administrators and clinicians to ensure that she and her fellow patients with ALS in Louisiana and Mississippi could access quality care closer to home. Annie is survived by her daughter Allison "Allie" M. Chatellier, former spouse and father of her children Maury O. Chatellier, father and stepmother Dr. Joseph A. Pellecchia (Nancy); siblings David Pellecchia (Zarina), Dr. Catherine Pellecchia Perry (Rod), Mary Pellecchia Bergeron-Tomeny (Richie), and Erin O'Connell Helf (Mark), 12 nieces and nephews, Phillip (Cat), Christina (Brandon), Rebecca, Alanna, Lauren (Kris), Stephanie, Sean, Caroline (Danny), Kristen (David), Miles, Heidi, and Jack. She is preceded in death by her infant daughter Rachel Marie-Noel Chatellier, mother Suzanne Stephenson Pellecchia and her grandparents, Andy and Angela Pellecchia and Charles and Naomi Stephenson.

Annie's family would like to express their heartfelt thanks to her close circle of friends and neighbors who were so supportive throughout her journey. A special thank you goes to her professional care teams at Halo, Inc. especially Kim Parker, and Heart of Hospice and her nurse Jessica.
