Something we can all learn from.” Dowse’s manager, Sandra Siegal of the Siegal Company, remembered her client and friend in a statement Sunday. “I am devastated at the loss of our extremely talented, beautiful, elegant, eloquent and beloved Denise, who I have had the pleasure and blessing of managing and working with in her career for over 25 years, as well as a personal friendship. I am at a loss , but I have gained so much from her knowledge. Denise’s legacy and memory will live on forever because she truly touched so many,” Segal said.
