She is also certified in Power Pilates mat and is a pelvic floor guru. Randi trains all body types and caters to people with varied interests – men and women who want to increase their flexibility, people who want to strengthen and lengthen their muscles for a longer and leaner look, people recovering from injuries, new mothers seeking to reach their potential, and athletes looking to improve sports performance and prevent injury. Randi’s clients range from professional athletes and sports team trainers to Broadway dancers to pre and post-natal women to people recuperating from injuries and trauma, like strokes. Pilates also keeps Randi herself fit so she can keep up with her teenage twins!



Diarra Cummings began teaching the Pilates method in 2008, following a career as a professional dancer touring with classical ballet and modern dance companies in the U.S. While earning a B.A. from The School of General Studies at Columbia University, Diarra completed her teacher training through Lawson Harris at The Fitness Guru Teaching Lab Pilates Apparatus Certification and her pre/post natal certification through Brigitte Arle at Little Bridge Pilates. Incorporating traditional and contemporary Pilates exercises, Diarra’s teaching emphasizes a conscious approach to movement with a focus on correct alignment and efficient biomechanics in a judgment free and supportive learning environment. Diarra strongly believes in the transformative power the mind has over the body and roots her teaching in the belief that physical heath and awareness are essential to reaching one’s optimum potential.

Diarra teaches Open Level Tower 9:00-9:50am and 7:00-7:50pm on Mondays and at 9:30am on Wednesdays.
