STOTT PILATES® Instructor
Meet Josie
Certified 2023
Josie Allen received her STOTT PILATES® training in Maui, HI in 2021. She is currently trained for the Essential, Intermediate, and Advanced Reformer. She has also been certified as a Mat Pilates teacher through The Foundry Yoga in AZ, which is recognized as a qualified school by the National Pilates Certification Program. Josie also has a background as a yoga teacher, and specializes in a style of hot yoga called Bikram Yoga. She completed her 200-hour yoga teacher training through The Foundry Yoga as well. When Josie is not teaching or practicing yoga and Pilates, she enjoys spending quality time with family and friends, recreating outdoors, and traveling.
Growing up as a competitive gymnast, Josie developed a passion for the potential of the human body at an early age. After quitting competitive gymnastics, Josie found joy in trying new athletic outlets like running, biking, snowboarding, and rock climbing, all of which she still enjoys to this day. At the age of 20, Josie attended an intensive 2-month training in Los Angeles, CA to become a Bikram Yoga instructor. She has taught for over nine years in different studios all over the United States, including in Kauai, HI, Beaverton, OR, and now, Flagstaff, AZ. After giving birth to her fourth child, Josie quit teaching hot yoga in order to dedicate herself to the growing needs of her young family.

During this time she took a break from her yoga practice and dove into the world of endurance sports. She competed successfully in triathlons, half-marathons, and various bike races. However, even though she enjoyed these sports, her overall health began to be compromised. Knowing she needed to change her lifestyle, Josie went back to her roots and began practicing yoga and attending Pilates classes. Her health and wellness resumed to a comfortable and balanced state, causing her to want to share the gift of teaching Bikram yoga and Pilates once again. She is excited to share her knowledge with others and to continue to grow and learn as an instructor and student!
At PILATES 66, Josie is currently offering Pilates Basic Individual Personalized Sessions. You can also find her teaching the Essential, All Levels Reformer, Cardio Jump, and Pilates Mat group classes! You will love Josie’s style and gift for providing a low-impact, alignment-focused workout that will lengthen, strengthen, and balance your body!
A quick fun fact… Did you know that Kelsey and Josie each have 6 kids? Yep, that’s 12 kids between the 2, so it’s really just natural for them to teach you all how to move, breath and be in your body; it’s just that simple!
Balanced Body Pilates Instructor
Meet Sandy
Certified 2007
Sandy did her Pilates teacher training in September of 2007 in La Jolla, California only a couple of months after her first, private Pilates session in Flagstaff. It was love at first sight; she instantly felt the potential for the overall improvement of the quality of life through Pilates. It was the perfect change in her career after leaving her professional life in retail and Porcelain painting behind when she moved from Germany to the US.
Sandy enjoys teaching Mat Pilates because she believes it represents the foundation & principles of Pilates in it’s purest form and appreciates how the Reformer and the Cadillac offer a great variety of exercises with a lot of room for modifications, support & resistance geared to the level of experience. Her favorite prop is the foam roller which can assist and/or support the client during the execution of an exercise. At the root of her love for Pilates is how it inspires her and those she works to live a healthy, strong and balanced life.
Sandy adds some spice and sauce to our team with her German teaching style which is something Joseph Pilates would be thrilled to know!
STOTT PILATES® Instructor
Meet Renata
Certified 2008
I did not take a straight path to becoming a Pilates instructor. At the outset of my career, it seemed like a great idea to get a master’s degree in international economics in Slovakia (my birth country) and continue with PhD studies in the Netherlands. Living in the Netherlands was great (I loved biking as a lifestyle), but doing international business research was not such a good idea after all.
Next thing I know, I was in California with my husband and then in Michigan, where our son was born. I discovered Pilates exercises when a couple injuries and surgeries landed me in chronic pain. I got hooked since my first private session and I absolutely needed to know HOW exactly it works. I was lucky enough to live close to a STOTT PILATES® training center where they build on the latest research in health and exercise science and regularly update their education programming. I trained with them on reformer, mat, stability chair, cadillac, and barrels and acquired my STOTT PILATES® Instructor certification in mat and reformer at Equilibrium Mind-Body Fitness, Bloomfield Hills, MI in 2008.
Over years, I continued my education and participated in various workshops, e.g., on scoliosis, knee injuries, special populations, athletic conditioning on V2max, biomechanics of functional movement, fascial movement, among others, which helped me understand WHY Pilates works. In between, I also tried to figure out the “protein craze” and took several semesters of Human Nutrition courses at ASU, which did not yield satisfactory answers.

When I am not teaching, I enjoy hiking with my dog and my family. I also discovered the joy of knitting and the rage of sewing. I am particularly fond of the combo of knitting and simultaneously watching Nordic noir with subtitles (truth to be told, I am still waiting for a presentable outcome of that combo). As a true glutton, I am always on the lookout for rich flavors and surprising combinations of ingredients, which occasionally leads me to questionable experiments in my kitchen. Otherwise, I am quite harmless.
If you join one of my Pilates sessions, I will try to make you feel more fluidity in your joints movements improving your range of motion, understand the gait biomechanics improving your posture, and activate the myofascial connections looking to achieve more resilient body.

She has been married to her husband Brian for twenty-seven amazing years and is a mom to three beautiful kids who are now grown and doing amazing things. She and her family enjoy going to the lake, camping, hiking, hunting, and fishing. Karrin joined Village Dental Care as a dental assistant in the fall of 2008, and transitioned up to the front in 2011, tackling the job of Office Manager. She has ALWAYS had a passion for fitness and wellness. With that said she completed months of training at High Altitude Personal Training and received her ACE certification. From there she trained with HAPT for a number of years while continuing to work at Village Dental Care. Along the way, meeting Kelsey Mercer, she began training under Kelsey with Pilates and absolutely LOVED it! Pilates has opened an entire world of fitness to Karrin, something that is effective, functional, core intentional, and gentle on the joints. She is incredibly happy and blessed to be a part of the PILATES 66 family!
STOTT PILATES® Instructor
Meet Bridget
Certified 2024
I’m a native Tucsonan and grew up in a big family with career-focused parents so participating in after-school sports was not really an option. I suppose that set the stage for me to go on to live a physically active life. Even now as I am in this wonderful retirement, senior citizen phase of life, I cannot imagine being physically inactive. Daily activity is a routine, a way of life, and a great endorphin rush that I need and hope to keep for many more years to come.
Of course, I had to recognize and make peace with modifying activity levels as I aged. With that I adapted to intentional and functional exercise which allows me to still do many of the exhilarating things I love, with moderation and lower intensity.
I spent my career in Fitness and Wellness then on to Public Health Education. I love to Mountain bike, Gravel bike, hike, weight lift, Yoga, Pilates, bocce ball, corn hole, and listen to live music.
In 2024 I completed STOTT Intensive Reformer certification with Kelsey and hope to move forward with additional training. My Pilates classes are fun, challenging, and always with a variety of good music. Come move with me!
