NICE TO MEET YOU. Welcome to the NEW

I'm Dr. Terry Zachary

My journey as a pro golfer & sports chiropractor showed me that the health & balance of the body (especially GRIP, HAND EXERCISE, POSTURE, & STRETCHING) is poorly understood not only in golf and other sports but in music, therapy, esports/gaming, computers, smartphones, hobby & the workplace.

As a wellness company, we’ve already helped over one million people improve their lives, not just their games. Our courses and products help people perform at their best!

doczac has the world exercising their hands & grip properly with Handmaster Plus. Now we aim to get the world stretching and putting properly with 'The 3-Minute Stretch' and 'Short Putt Mastery.'  Mastery leads to both fulfillment and contentment.

About Us

“The Handmaster Plus hand strengthening device is an essential piece of apparatus. It universally addresses the intrinsic muscles of the hand, wrist, forearm and elbow. It is a valuable tool for any physiotherapy practice.”

-Alex McKechnie, MCSP, MCPA (physiotherapist), Master Trainer & developer of the Reebok Coreboard

“The Handmaster Plus hand therapy device is simple to use, easy to explain and affordable to anyone. My patients love it. They take it home with them…and actually use it! I recommend it to everyone to keep their hands, wrists, carpal tunnels and elbows balanced, healthy and feeling great.”

-Dr. Vanessa Anderson, (chiropractor) Moline, IL USA

"I've never stretched enough and it was always on my mind, but the stretches I knew were awkward & time-consuming. 'The 3-Minute Stretch' already has my whole body feeling better. And it's so simple, I can do it anywhere & anytime. It's been a godsend."

- Heather Thompson, Ottawa, ON Canada
