Gretchen Bosselmann-May
Gretchen is the founder and owner of TruForm Pilates Scottsdale, a premier Classical Pilates studio dedicated to preserving the authenticity and integrity of the method. She is a National Pilates Certification Program (NCPT®) Certified Pilates Teacher.
A classically trained instructor, Gretchen completed her comprehensive certification through Power Pilates in 2016 and earned her NCPT® certification in 2018. As a second-generation Pilates teacher, she furthered her expertise through an intensive 160-hour Master’s and Mentorship program with Lolita San Miguel—one of only two instructors personally certified by Joseph Pilates.
In 2021, Gretchen was selected as one of just ten instructors worldwide to participate in Kathi Ross-Nash’s prestigious Professional Pilates Advanced Teacher Training Program (PPATT), an immersive program focused on the deeper relationships within the Pilates system and its precise application. She was later chosen as one of only twelve instructors to continue into PPATT Level 2, graduating in July 2025.
Gretchen continues to study with Kathi Ross-Nash, traveling to Florida several times each year to participate in continuing education workshops. She firmly believes that as a Pilates instructor, you never stop being a student of the method.
Gretchen continues to refine her practice under the mentorship of Michael Fritzke, a direct apprentice of Romana Kryzanowska. Through this lineage, she gains rare, firsthand insight into the traditional apprenticeship model and the true essence of the Classical Pilates Method.
Deeply committed to her clients and her own ongoing practice, Gretchen brings a thoughtful, individualized approach to every session—honoring the legacy of Pilates while helping each client build strength, balance, and control.
Outside the studio, she enjoys spending time with her husband and their beloved French Bulldogs, drawing joy and inspiration from their companionship.
