My sincerest and most heartfelt condolences to Mr. Testo´s family. I was one of his algebra students at Lincoln in the mid-70s. He was a fantastic teacher and so well-loved. Mr. Testo remained as one of my most memorable and favorite teachers ever. We were so lucky! May his memory be eternal and a blessing to all who knew him.
