Gabriel Halpern is also coming to NYC July 25th and 26th for a workshop called: Sharpening The Edge of Your Practice and THE NECK: Bridging the Gap Between the Chest & the Brain. Both look amazing and should not be missed. Gabrile has been practicing since the 1970's and trained at the Iyengar Institute in San Francisco and Pune, India. He is the founder and director of the Yoga Circle in Chicago, IL since 1985.
