“Dr. Kassar is absolutely wonderful! He takes time to review lab work, medicines and any concerns you may have. His bedside manner is exceptional. His staff is pleasant and helpful. I travel from Florida a few times a year to continue to have Dr. Kassar follow my diabetes as I don't want to change my endocrinologist.”
