Howard M. Kassler

have a memory or condolence to add?

Sandra (Kassler) Flannery

November 27, 2019

I have always had a warm spot in my heart for Howard- and Haskel. They seemed to be my father's (Louis Kassler) favorite cousins and were warm and loving and intelligent to be with. Howard was also my dental surgeon and I have never been able to trust anyone like I trusted him with procedures.
I have missed my association with Howard and the extended family and want to express deep condolences on his passing.
May his memory be a blessing to all of you as it is for me.
