Di was active in the Highland Park School PTA serving as president and the Glenbrook Swim and Tennis Club where she and her family spend many enjoyable summers. As the children grew older Di continued her retail career at the Lucy Baltzell Shop in West Hartford Center working side by side with her beloved sister Nancy. Di's lifelong interest in gardening led to active involvement with the Manchester Garden Club, the Perennial Planters, and their community landscape committee; her commitment and enjoyment of gardening clearly shown through with the many times their Manchester home was featured in local and national garden tours. Another important part of Di and Roy's life together was their time spend in Kennebunk Beach, Maine at the Powers family cottage with her parents, her sister and brother and eventually her own family.
