My sincere condolences to Mr. Karsten's family. He was my 5th grade teacher at the Old Mystic Elementary School and my science teacher at Mystic Jr. High. He was my most favorite teacher of all time. He certainly had a very important role in my early development and education. He was the best of the best and I will always remember him fondly. I am so sorry to hear of his passing. MT thoughts and prayers are with you all. God Bless You.
