Bonnie is one of the most influential people in my life. I was her student for a couple of years. I never became a concert pianist or some amazing performer, but she helped me develop confidence and a strong sense of self that blessed me in many ways. She saw the good in me when I was super insecure about myself. She was always happy and silly and I left every single lesson feeling more optimistic and wanting to be like Bonnie. What a blessing to have known her and been so influenced by someone so fundamentally good and Christlike. Love you Bonnie.

The Provo 8th Ward had many wonderful leaders when I was a new deacon. The Wintertons were certainly among the most caring. They blessed my life by the "sermons of service" that they taught by living gospel principles. Thank you, Boyd and Bonnier, for those lasting memories!

Bonnie was the personification of light, love and service--qualities that were a part of her very being. When she and her ever-supportive husband Boyd hosted large choirs for the Church in the Conference Center they were the perfect team, bringing their unique gifts together into one united whole. I express my heartfelt love to their amicable family.

Bonnie had a profound impact on my life. I studied piano with her for many years and stayed in contact for many more. Bonnie once said to me that it is a holy thing to be in the heart of a child. I have always remembered that with my own students. She spent more than one lesson just talking to me, giving advice and wisdom. She told me to become a piano teacher. I was sitting in my lesson when her son called to tell her he had been accepted to Harvard medical school. When my mom forgot to pick me up she made me wait in her living room and brought me tuna casserole to eat for dinner. When I called to say I couldn´t come to my lesson because I didn´t have a ride she put on her hat, coat, and gloves, got in her car, and drove to my house to give me a lesson. She gave me materials to teach piano on my mission in the Philippines. She gave me a primary song book at my wedding and told my husband that he was lucky because we would have music in our home and children with long fingers! When I was experiencing infertility she told me to eat more blueberries. I had the honor of performing at her retirement recital in Libby Gardner Hall. She helped me prepare for a performance in the BYU Marriott Center and even offered to listen and help with my first concerto student when I was a new teacher. So many memories! Thank you for sharing this beautiful woman with all of us. Her influence has impacted the whole world. She is elegant and delightful, strong and intelligent, and one of my dearest friends and favorite people. It is an honor to know and love her. ~Kara Baird Carlston

Bonnie blessed my life with music. At age 17, Bonnie was my piano teacher. She always focused on hymns in addition to the classical repertoire. She provided me with an idea for my eagle project. She set me up to play the organ for the LDS Veterans Hospital sacrament service for one year. This is were I learned to play the organ. Now at age 65, I look back at what a blessing it has been in my life, to play the organ for every ward I have attended, including on my mission. I will always be grateful for Bonnie, giving me that gift. I love this Lady

How very much I love the GREAT Bonnie Winterton. There are just not enough superlatives to describe her. She touched so many lives, and she freely used her talents to help others. I was lucky enough to serve on the Primary General Board with Bonnie and specifically on the music committee. She taught me so much. Her love of music just spilled out of her. She was so enthusiastic and full of spirit and it radiated out to those she taught. I was also lucky to sing in one of the general conference choirs she directed. It was such a joy! Bonnie had a way of getting you to sing beautifully, feel the spirit of the music and have fun- all at the same time. What a gift Bonnie was to all who knew her. I always appreciated the way Bonnie treated people. She treated everyone kindly and made everyone feel important. Bonnie just brightened up the world. I feel so lucky to be her friend. Perhaps if I really work hard, I can be in one of her choirs in heaven. Thank you to the family for the beautiful funeral and thanks for making it available online. Elaine Anderson

Bonnie is my hero. She was my piano teacher for about six years and she has changed my life. She taught me so much more than piano. She had a way of making people feel like they were the most important person in the world. She exuded joy and love in everything she did. I love her so much! I am collecting memories of Bonnie from her former piano students. If you or your children studied with her, please visit and share your memories of her.

Bonnie, and her dear sweetheart Boyd, were such wonderful lights in our family's life. Boyd grew up in Charleston, where my father's family lived so we had a common bond before our children began piano lessons from Bonnie. Four of our eight children were blessed by taking from her. When I told them of her passing I received back the following texts: From Rick, "I only took a year from her in high school, but in that one year I learned a ton." Our three girls all have taught piano and served as their Ward's organists and pianists : Kathy: "She made a huge difference in my life. I'm grateful to her for that. She pushed my piano skills to a higher level." Mary: "Wow. I think of her often. Such is the life of the eternal organist. No fingernails or chewing gum for me...I have a job to do." Sharon: "Ironically what I remember thinking was 'No way!' When she told me being a piano teacher was a huge blessing in her life and I should be one too. I've taught 20+ kids now, paid for my piano many times over and yes thought that piano teaching is a huge blessing." She became my friend as she taught my children. And I credit her with the fact that I was prepared to speak when she challenged me to go back and brush up on my Spanish two years before my husband and I were called to serve in Argentina. May your family be blessed as you live the legacy of faith your parents and grandparents left you. With love, Wendy and Toney Bentley

Bonnie was one of the most influential people in my life! My piano teacher for 5 years, she saw goodness in me where I didn´t. She cause me to LOVE piano! She trained me to want to use my talent for service (been an organist/accompanist for 40 years). Taught me how to approach life with positivity, enthusiasm, zest and love. What an Incredible woman! Raised awesome kids in addition to ALL her own service and accomplishments. Amazing! Just a bundle a energy! One of God´s favored, and beloved daughters has returned home. Love you Bonnie!

I served on the Primary General Board with Bonnie Winterton and what a privilege and blessing this was! Bonnie had a way of making everyone feel loved and needed. We all loved her so very much. I have tears on my cheeks as I am writing this tribute to Bonnie. She was "one of a kind!" I remember our meetings with her - She always brought us a treat! Bonnie WAS a treat, no matter what meeting we were in with her. She and I shared the love of music, piano being our favorite! Bonnie was one of the most intelligent, kind, talented people I have ever known. We want to thank Bonnie's family for taking such good care of our beautiful one-of-a-kind ray of sunshine. We know you took great care of Angel Bonnie Winterton! Much love, Kay Lynn and Garth Wakefield

Your wonderful Mother was an incredible influence for good for my daughters, Natalie and Stephanie. Under her guidance their joy of playing the piano grew by leaps and bounds. She was especially kind to our Stephanie by having her play her U of U senior concert numbers in a "get the jitters out" rehearsal at your home two nights before her final performance. I had the opportunity of serving on the Primary General Board with Bonnie. She was positive, gifted and always happy to serve in any capacity. It was a joy to know and love dear Bonnie.

Oh how I loved Bonnie. One time as she dropped me off, we sat in my driveway while she shared part of her patriarchal blessing with me and explained how her life and career had taken the direction of music. I also remember the time she, as a committee chairman of a Primary General Board group, felt frustrated with all of us who were "late." She and all of us laughed as she realized the hour had changed because of Daylight Savings Time.

I´m so sorry to hear about Bonnie´s passing. She had a great influence on me growing up in the ward and later in the choral world. Her musical talents, enthusiasm and positive attitude are unsurpassed. May the Lord bless you at this time of separation.
