Sandra Danby


Sandra embarked on her professional dance journey at the age of eleven with contracts at the Scala Theatre and the Derby Hippodrome. Her early successes led her to the Carol Levis "Junior Discoveries" Talent Show and Pantomime, where she played Girl Babe in "Babes in the Wood" alongside Marti Wild. She continued in pantomime with roles in "Goodie Two Shoes" and "Robinson Crusoe."

At 16, Sandra entered the world of "Billy Smart's Circus," showcasing her talents in aerial ballet, performing forty feet up without a net. She returned to dancing in the touring West End cabaret "Limelight," visiting Eastbourne, the Isle of Wight, and Pier Pavilion, Cromer.

While still pursuing her passion for dance, Sandra took on a new role at 18 by opening the Miss Sandra School of Dance in Brentwood, Doddinghurst, and Ingatestone. The three schools later merged to become the San-Marie Stage School.

In 1994, Sandra retired from teaching, passing the torch to her daughter Lisa-Marie to carry on the legacy of the school. Her journey is a testament to a lifelong dedication to dance and the arts.
