In the summer of 2019, Lexi studied in Seattle, WA. with Anne Green Gilbert, the founder of Brain Compatible Dance Education, earning her certificate as a BCD educator.

Based on brain/body developmental research, this teaching protocol uses conceptual learning to develop holistically trained dancers who are skilled technicians, inventive creators, critical thinkers, and successful collaborators, in the words of A.G.G. This curriculum focuses on an adapted vocabulary of Rudolph von Laban’s space, time, force, and body elements of movement.

Lexi’s classes include solo and group activities that foster self confidence, as well as social skills; students end each class with a reflection of the concepts explored, strengthening self-awareness and critical thinking. Miss Lexi’s warm and enthusiastic nature provides students with a safe space to learn, express, and grow.

Shannon Booth

Shannon Booth has been dancing since she was very little.  She spent the majority of her youth and teenage years dancing almost every day and traveling with her dance teams. In college, she continued her path as a dancer on her school’s dance team while beginning to student teach and assist in dance classes. Shortly after that she began teaching her very own classes and has been ever since. During this time she also performed with “Jamming with the Jets” and performed at the Jets halftime show. She also danced in many Easter Day parades during college. Shannon later joined a small off-Broadway tap company and performed in a few venues with them for about 2 years.  After college, she continued to teach dance and share her love for dance with many children of all ages in all styles and genres of dance and worked in many studios across Long Island. Shannon helped choreograph many award-winning numbers that she is very proud of. She continues to take classes and study dance to continue to broaden her craft.  She truly loves what she does and loves being in the studio. Shannon loves watching her students grow and thrive. 

When Shannon is not at the studio, she is home raising three beautiful children who she believes share in my love for the arts too and I hope they always will as they continue to grow. She looks forward to continuing to teach for many years to come and I’m so thrilled to be a part of such a special environment and to be a member of the Posey dance family! It’s definitely a great feeling when you love your job and are surrounded by wonderful students and staff. Thank you for allowing me to be a part of your children’s journey 5678…dance! 💖
