Iyengar Yoga Certification is a rigorous process held to a high standard and governed by the Iyengar Yoga National Association of the United States (IYNAUS). Certificates are earned only after years of training, study, and evaluation. Candidates being assessed for certification are expected to be proficient in many practical and educational skills.

The criteria for these evaluations, as well as the structure of the certification process, were established by BKS Iyengar. This system articulates his teaching methods, and provides credentials for individuals pursuing the path of yoga instruction.

Currently there are many levels, or grades, of certificates. Higher levels indicate that the instructor has a depth of knowledge, practice, teaching skills, and class room experience.

The certification mark has been developed to establish recognition for the work and merits of this program. It is your guarantee of a teacher that has developed, and been assessed for, a level of competency and maturity.

Look for the mark!

Patrina Dobish is a Certified Intermediate Junior 2 Iyengar Yoga teacher, and has studied yoga her entire adult life. She helped found the Yoga Tree and is the Managing Director. Patrina has attended 19 weeks at RIMYI (Ramamani Iyengar Memorial Yoga Institute) learning from Geeta, Prashant and BKS Iyengar. Acknowledgement goes out to several stewards of Mr Iyengar, in particular, Laurie Blakeney, Mary Reilly, Patricia Walden, Manouso Manos, Lois Steinberg, and Chris Saudek. She’s participated in every Iyengar Yoga Convention held in the United States since 2001, and was at the Estes Park convention where BKS Iyengar taught.

Her community service includes a 4 year term on the IYNAUS board, ombudsperson for the 2001 and 2007 convention magazines, and the reestablishment of the Iyengar Yoga Association of the Midwest (IYAMW).



Patrina feels very lucky to be able to practice and teach yoga. Iyengar yoga injects a glimmer of understanding into this subject. She brings to her classroom a love of yoga, joy and humor. She teaches, as an artisan would work, honing and refining to stabilize and mobilize to integrate the layers of our being.

His background in creative and performing arts, and his interest in world civilizations, inform his practice and teaching.  Iyengar Yoga embodies a culture.  It is rich with traditions, articulated practices, specialized language, iconography and an ethical standard.  Bob endeavors that his classes enlighten students on that vast body of knowledge, and inspire them towards their own excavation of, and enculturation into, the opulence of Iyengar Yoga.

Aroused by the power of the spoken and written word, Bob has worked on the editorial staff of the magazines for 2 IYNAUS conventions, Odyssey 2001 and Yatra (2007).  He served the editor-in-chief for Lois Steinberg’s  Geeta’s Guide to a Woman’s Yoga Practice, Volume 1 (2005), Steinberg’s 2010 Iyengar Yoga Asana Alternatives:  The Neck and Shoulders and has contributed numerous articles and interviews for publication on the subject on Iyengar Yoga.  Bob served on the Curriculum Committee for IYNAUS’ 2010 REFLECTION convention in Portland OR and as Special Events Chair for the successful FROM THE HEARTLAND, the first Iyengar Yoga conference held in Chicago (2011).

David Carpenter



Jerry first attended an Iyengar Yoga class in his native Chicago and quickly realized the beneficial effects of yoga. This led him to move to Urbana, IL for eight years to study daily with Advanced Certified Iyengar Yoga Teacher Lois Steinberg at the Iyengar Yoga Institute of Champaign-Urbana. Later, he began teaching there and at The University of Illinois Urbana-Champaign. Jerry assisted Lois in a variety of classes including the Women's Essentials and Yoga Therapeutic classes. He also taught Men’s Essentials, beginner and experienced classes, and the specialized healing classes for knees, low back and neck & shoulders. He moved back to Chicago in Summer 2015. Jerry is an Intermediate I Certified Iyengar Yoga Teacher and has a degree from Drake University in Actuarial Science. Others have described Jerry as the calm in the eye of the storm!

David Carpenter is a Certified Iyengar Yoga Teacher. He also is now the President of the Iyengar Yoga National Association of the United States (IYNAUS).

David began studying Iyengar yoga in 2000, the year he turned 50, when he was beset by athletic injuries and was experiencing great stress from his career as a lawyer who argued cases in the U.S. Supreme Court and other courts.  Yoga has enabled him to overcome neck/shoulder, low back, hip, and knee injuries as well as several organic maladies.

David is a long time student of Lois Steinberg who holds on Advanced II certificate from BKS Iyengar and who has extensively taught, and written about, therapeutic applications of Iyengar Yoga. David also regularly studies with Advanced certificate holders Laurie Blakeney, Manouso Manos, Joan White, and Chris Saudek as well as with Chicago's wonderful Certified Iyengar Yoga Teachers.


Lorene Zant is currently certified at the Intermediate 1 level and has practiced Iyengar yoga since 2001. Her first introduction to Iyengar Yoga in Long Island, NY was enlightening and informed her decision to become a serious student of Iyengar Yoga, and her early studies and apprenticeship under Senior Iyengar Yoga Teacher Joan White was transformational. Since moving to the Chicago area there have been opportunities to study with phenomenal senior level teachers Laurie Blakeney, Manouso Manos and Mary Reilly. In 2015, Lorene attended Yoganusasanam in Pune led by Geeta, as well as classes with Geeta and Prashant in Bellur, India (BKS’s birthplace) in celebration of the opening of a spectacular Iyengar Yoga hall. In fall 2017 she will return to Pune to study at the BKS Iyengar Institute (RIMYI) for the month of October.  She also participates in teacher trainings throughout the country as well as national and regional Iyengar Yoga conventions.


Being an Iyengar Yoga teacher lights paths that would not be possible otherwise, and the integration of teaching as well as practicing as a Registered Nurse allows Lorene to create a synergy that is mentally, physically and spiritually supportive. In addition to teaching at Yoga Tree of Evanston, she also teaches weekly classes at a local homeless shelter, and will begin grad school in spring 2018 to pursue becoming a Family Nurse Practitioner.  Lorene was on the IYAMW (Iyengar Yoga Association of the Midwest) Board of Directors for three years, served as board President, and was chairperson for several committees.

Achala Jeff LeGro is a certified Iyengar Yoga Teacher. He studies regularly with senior Iyengar method teachers, Laurie Blakeney, Chris Saudek and Lois Steinberg. Patrina was his first teacher and continues to be his mentor. Achala will never forget his first class with her because it was on the morning of 9/11!

Achala is a graduate of the School of the Art Institute of Chicago, runs his own remodeling & handyman business, and although yoga started out as something to do with his now departed wife, Achala found it to be a perfect complement to his longstanding zen meditation practice (How better to embody your concentration practice than by doing yoga poses!). He developed a daily yoga practice by the late 2000's, and became certified to teach in 2014. He brings to his teaching: enthusiasm for the subject, the eye of an artist, compassion for those facing life's challenges and a desire to have fun along the way.
