Condolence: I knew Dr. Grosack for 12 years as my customer at Kinney Drugs. During that time, he became a friend. My respect for him was immeasurable. He was one of the kindest and most decent gentlemen I have ever known. He genuinely cared about me and my life and it was obvious how much he cared for, and was proud of, his family. When my wife had some issues with her feet, I knew exactly where to send her and he treated her with such gentle care. All the folks at Kinney thought so highly of him, with his friendly smile. I was shocked when I learned of it this afternoon. I am so sorry Dr. Nancy, kids, spouses, and grandkids. Our thoughts and prayers are with you and if you need anything please let us know. We have lost a great one in Dr. Grosack.
