"The Happy Back Training with Rachel was an incredibly valuable experience. It has

given me more confidence teaching my classes, knowing that I can safely instruct

students who come to me with back pain. I was able to start using Rachel’s

therapeutic sequences immediately in my classes and my students are very happy!

Thanks Rachel!"

- Julia Chen, RYT San Diego, CA


"I was completely impressed with the Happy Back program. It is a well-structured

curriculum that provides a highly dynamic learning environment and prepares

students well for the challenges of assessing, treating, and instructing clients on the

health and management of their spine. As a physical therapist new to the

therapeutic aspects of yoga, I felt it was highly valuable, very applicable, and

tremendously thought provoking. Rachel is superb, her teaching is outstanding,

entertaining, relevant, and genuinely instructive. How lucky we are to do what we

love. Take this class. Two thumbs up!"

-Barbara Shirts, PT San Diego, CA


“Rachel is a teacher’s teacher. As a seasoned physical therapist and healthy back

expert, she brings a broad base of knowledge and the confidence that comes from

experience, to every injury and interaction. Her gentle way and healing hands have

helped me manage my back issues and her full and purposeful life inspire me to live

my life mindfully.”

-Shauna MacKay, BPE, RYT-500 San Diego, CA


“As a health care professional, Rachel brings in-depth knowledge and insight to her

teaching that is an invaluable benefit to her students.   Her expertise regarding

musculoskeletal mechanics and pathology, combined with her compassionate

instinct as a healer, form the perfect union of precision and tenderness.  It was my

privilege to study with Rachel and I gained an enhanced expertise and skill in yoga

therapy, anatomy and kinesiology.  This training is essential for any yoga teacher

seeking a deeper knowledge of how to safely and competently guide students with

injuries and joint problems safely through their yoga practices.”

-Ingrid Yang, author of Hatha Yoga Asanas, yoga teacher, and medical student

Chicago, IL


” After the very first time I used Rachel’s instruction to free up the shoulders and

neck several of my students said they felt relief from persistent and long term

tension and pressure. The simplicity of the poses made them useful for each and

every student with a minimum of adjustment, which is great for a relatively large

class. It works like magic. ”

-Aliza Herbst, Yoga Teacher     Jerusalem, Israel


“Rachel’s workshops combine sound scientifically-based knowledge with the

wisdom of Yoga.  Rachel is an eloquent speaker, a natural teacher and a gifted

healer.  I felt like I learned more than I expected to learn in an experiential way and

had a lot of fun doing it.”

-Christine Carr, MSPT, COMT, RYT Denver, CO


“Rachel Krentzman is a widely trusted practitioner who combines scientific

knowledge with yogic intuition to provide a full complement of treatments for the

back, neck and shoulder. As a “patient” with scoliosis I can attest to the skill with

which she examines the spine, hips and shoulders, and prescribes appropriate

exercises to release tightness and relieve pain. As a yoga instructor who learned so

much from her weekend long workshop, I deeply appreciate the detailed anatomical

knowledge her training as a physical therapist has given her. Rachel also has a rich

background as a Purna Yoga teacher and possesses natural sympathy and kindness

toward students. No wonder she is so respected in San Diego!”

“Krentzman’s Yoga for a Happy Back DVD is a wonderful support for students

looking for a solid, therapeutic sequence to practice at home. Research has

demonstrated such a tool increases ongoing participation in a home asana practice.

The DVD is laid out in a logical sequence, using three models of varying

ability/mobility in order to clearly demonstrate adaptations and modifications of

the asana. The two camera views give the viewer a well-lit perspective of alignment,

support and body placement. Divided by type of asana, each section can be part of

the entire series or stand alone as a shorter practice. It was particularly nice to have

a narration with a solid, professional tone and no dreamy, elongated “yoga voice”.

Careful detail is given to the use of props and other supports without impeding the

series progression. Especially noteworthy is the care taken to walk the student back

out of the asana safely where so often the viewer in other DVD’s is left to find their

way out. Next time someone you know is complaining of back pain, send them to a

qualified yoga instructor and suggest they pick up Yoga for a Happy Back to find

their way home to freedom of movement again!”

-Matthew J. Taylor, PT, PhD, ERYT, Past president of the board of directors of the

International Association of Yoga Therapists; founder of the Matthew J. Taylor

“As a power vinyasa yoga teacher, the yoga that I teach is very dynamic and often

flows from pose to pose in a “one breath, one movement" sequence. Taking Rachel’s

Happy Back Training enhanced my skills as a power yoga instructor: sharpening my

skills of giving proper alignment in the most comprehensible terms, knowing

excellent modifications for those who require it, better understanding of the fine

details of anatomy, and an increased awareness of how to address the needs of

practitioners recovering from injuries ranging from pain in the joints to the back to

the neck.

Rachel’s class is interactive, organized, fun, and filled with hands on techniques that

we practiced on one another.  We were given fantastic sequences to use in our

teaching for specific issues. The training has been invaluable to me as both a teacher

and a practitioner of yoga.”

-Sherilyn Mandelbaum, Yoga Instructor and Owner of Your Yoga Ra’anana, Israel



"The wisdom and expertise shared by Jaimie and Rachel has been such a tremendous

gift. In these ten days, my personal practice has shifted to become much safer,

smarter, and sustainable. In my group classes and private sessions, I feel much more

well-equipped to offer modifications and sequences for specific spinal ailments."



"The Yoga for a Happy Back Teacher Training has allowed me to better integrate my

yoga therapy knowledge into my osteopathic medical practice. I gained new insights

into the therapeutic application of functional anatomy principles through yoga

asanas. I will be bringing many of these techniques back to my practice. I know my

new knowledge will be of great benefit to my patients!"

-Laura Sobiek DO, San Diego 2015


"I now know the anatomical reasons why I teach certain poses. I understand how I

can better help my students. And I am now my own testimonial of how Happy

Back can heal the body and soul since in just 10 days I have been able to make

enough progress physically where I can squat beyond a 90° bend in my knees.

And I have learned so much about myself and what I can work on in order to lead

a happier life. Basically I'm more in tune, than ever, about what causes me stress

and what flares my injuries. Thank you for this life changing experience!"
