    Dear Lisa and Andy,
    I’m so sorry to hear of your mother’s passing. She was always so youthful and full of life! I saw her a few years ago at Art Fair Off the Square in Madison. It was nice to reconnect! I’m happy to say I have an original Leslie Trewyn art piece. She’ll be remembered fondly.

    My sympathy to all of Leslie’s family. May you find peace in your memories of the loving free spirit that she was. She no longer has to keep up the fight. May she rest in peace ?

    We were blessed to have Leslie join us for our annual artist in residence day at Friendship Learning Center in North Fond du Lac two years ago. Prior to the residency the fourth and fifth grade students painted noteworthy landscape and portrait paintings inspired by her colorful layered style. Leslie shined as she interacted with the students and demonstrated her artistic passion. I will miss our conversations at Green Lake each year and the colorful joy she created on canvas. Her book is a lasting treasure. May your family be comforted by the memories of a strong woman who embraced her strengths.

    My sympathies to Tom and the rest of Leslie’s family. Leslie was a lovely and very talented person. We played doubles tennis together and she was a wickedly good player. My husband is an artist and he knew Leslie from the art fair circuit. We enjoyed seeing her colorful paintings. She will be greatly missed.

    Leslie was my oldest cousin and I always looked up to her. She was talented, intelligent, had a great sense of humor, loving to friends and family.
    I’m grateful I was able to talk to her earlier this year. It was right before she returned home from the hospital in Madison. We reminisced about the past (she and Tom visited our house in California at Thanksgiving several years ago). She seemed in good spirits and was hoping to make it until her birthday in June. I told her I might be in Wisconsin around that time and would probably see her then.
    I was sorry to hear about her passing just a few weeks later. She’ll be missed. My wife, Charlotte, and I are hoping we’ll be able to make it to her memorial service in June .

    She was my art teacher in school

    So sorry to hear. She was a wonderful dedicated lady married to Tim who was my practice teacher in 1967 at the junior high/grade school on Main st. He was the best of human beings and taught me how to be a great teacher. I moved to Milwaukee and lost track. I coached football with Lou Pluim and taught geography at the high school. I owe them both a great deal and am sorry to hear of their untimely deaths. I know I will se the again in a better place where I can thank them.
