A board-certified veterinary oncologist, Dr. Cletzer’s clinical interests include lymphoma, histiocytic sarcoma, targeted therapies, and immunotherapies. She is dedicated to helping families navigate a cancer diagnosis with compassion, honesty, and hope. Dr. Cletzer values creating individualized treatment plans that balance advanced medicine with each family’s unique goals, always striving to improve both quality of life and the time pets share with their loved ones.
Outside of work, Dr. Cletzer enjoys spending time with her husband and young daughter, attending sporting events, and relaxing with a good book. She shares her home with a sweet gray tabby cat adopted from Tufts—who has traveled all over the eastern United States with her—and a Boston Terrier she proudly calls “the best dog ever.”
