Emily Cooke - Ballet, Pilates, Pointe, Stretch & Variations - Student Division


Emily Cooke has been dancing since the age of 3.  She began studying at Salt Creek Ballet under the direction of Patricia Sigurdson former Principal dancer of American Ballet Theater.  At that time, she had the pleasure of learning from Julie Kent, Susan O’Connell, Luba Gulyaeva and Randall Newsom.  The next stage of her training was at the Rockford Dance Company under Artistic Director Joy Xu a former Principal dancer with the Shanghai Ballet while continuing to work with Randall Newsom at Northern Illinois University.  An amazing summer intensive program brought Emily to the Judith Svalander School of Ballet in the mid 1990’s.  Judith provided a different approach to ballet given her background as a Soloist with the Swedish National Touring Theatre as well as the Swedish Ballet of Gothenburg.  Emily not only received top-level training in ballet but modern, choreography, partnering and jazz.  The faculty included Principal and Soloist members of Hubbard Street Dance Chicago, Alvin Ailey and Milwaukee Ballet.  This exposure to Milwaukee Ballet prompted Emily to audition and receive a scholarship to their summer intensive program. 

The next phase in Emily’s journey was with Ballet Chicago.  She danced under the instruction of Daniel Duell former Principal of New York City Ballet as well as Director/Ballet Mistress Patricia Blair.  Emily felt honored to be in the presence of such talented individuals.  Mr. Duell was taught and coached by Mr. George Balanchine on a daily basis which brought his presence into the studio each and every day. 

Emily made the difficult decision to go to college instead of continuing with Ballet Chicago; however, she utilized her background to receive a scholarship in ballet and choreography.  Dance has always been a part of Emily’s life.  She continued to dance and choreograph throughout college and beyond.

Rockford Dance Company is the perfect home for Emily to give back to students by teaching them the classical ballet fundamentals, pointe technique, partnering, Yoga, Pilates, strength, conditioning and performance essence that she graciously received throughout her dance career.
