JUSTIN HEROLD has been practicing yoga since 1979. He first started with the intention of reducing or overcoming running related injuries received during his long distance running or cross-country training. He ran to maintain good health but slowly discovered that the Yoga practice provided the most complete and safest system for keeping healthy. He finally traded his running shoes in for a Yoga training mat. He took a two-year intensive teacher training program, received his Iyengar Yoga Teacher Training Certification, and began teaching Yoga at the Iyengar Yoga Institute of Los Angeles, (IYILA) in 1989. He served as a staff instructor at IYILA from 1989 to 1992. From June of 1992 he has worked as an independent Yoga in Bangkok. He opened the IYENGAR YOGA STUDIO of Bangkok in October of 1999 and has been conducting classes there since. He travels to India on a regular basis to continue his studies with the Iyengars; B.K.S., Geeta and Prashant.

NILUBON LERTVANANGKUL (MU) first started her yoga studies with Khun Noo  in 1998.  Around a year later  she found the newly opened Iyengar Yoga Studio, Bangkok and immediately became addicted to the  personal, detailed method.  This brought about improvement to a long term knee problem she developed playing volleyball at university.  As she continued her studies she realized teaching would be the next step in her yoga practice and thus came to apprentice with Justin.

SUTTHANA VICHITRANANDA (PUI) first introduction to yoga was in Justin’s yoga class at the Marriott Hotel in 1999.  Later she spent 2 years studying Sivananda Yoga with Khun Noo.  She found herself most at home in the detail and precision of Iyengar Yoga so she has immersed herself in practice and studying at the Iyengar Yoga Studio Bangkok since 2005.  She began her apprenticeship with Justin in 2006.
