Founder of grit + tonic/CarmelBarre

Arianne Bautista Marsh is a certified Pilates instructor through Balanced Body and the founder of grit + tonic and CarmelBarre, studios dedicated to intelligent, athletic reformer Pilates in Monterey and Carmel. Raised on the Monterey Peninsula, she grew up running marathons, playing tennis, and competing in cheerleading and snowboarding—an athletic foundation that shapes her performance‑minded, strength‑focused approach to movement today.

After discovering barre in the San Francisco Bay Area, Arianne trained and taught under one of the method’s early leaders before returning home to open CarmelBarre in 2014. She has continued her Pilates education with respected educators including Tracey Mallett, among others, and is known for building creative, athletic sequences that challenge the norm—borrowing from sport, strength work, and Pilates to keep clients progressing, not plateauing.

grit + tonic is the evolution of her philosophy: precise, purposeful training that refuses to stay on autopilot, delivered in a focused, welcoming environment. Her classes emphasize clean form, progressive strength, and thoughtful programming that support everyday movers and athletes alike—whether they’re cross‑training, building resilience, or coming back from time off.

Arianne is committed to running studios where people feel known, challenged, and supported—not judged or boxed into one “type” of athlete. She lives in Carmel with her husband, two daughters, and their dogs.

Cathy’s passion for Pilates began in 2015 at a small, locally owned studio in Pacific Grove. What started as a personal wellness journey quickly evolved into a deeper appreciation for the benefits of Pilates—improved flexibility, reduced back pain - from past sports injuries - and enhanced functional movement.

Inspired by her own transformation, Cathy felt compelled to help others reconnect with their bodies through mindful movement. Her desire to support community members in recovering from injuries and improving their overall well-being is what led her to pursue teaching.

In February 2025, Cathy enrolled in the 500-hour Comprehensive Teacher Training Program at Club Pilates. This intensive certification includes instruction in Mat, Reformer, EXO Chair, Springboard, and Cadillac apparatus.

In addition to her passion for fitness, Cathy works in Finance and has + 25 years of experience. When she’s not practicing or teaching Pilates, you’ll likely find her spending time with family and friends, enjoying the beach, hiking at Garland Ranch, or practicing QiGong and Tai Chi with her neighbors.

Jill brings over 20 years of experience as a personal trainer, yoga instructor and movement coach to her Pilates practice at grit + tonic. She discovered Pilates five years ago as a client, seeking relief from birth injuries through private reformer sessions. The transformation she experienced was so profound that she decided to become an instructor herself.

For Jill, Pilates is the perfect complement to strength training—it addresses what lifting alone cannot. While weights build muscle and power, Pilates supports our structures from the inside out, creating the core stability, body awareness, and functional movement patterns that make us resilient in daily life. As a woman in her late forties who lifts weights, Jill understands firsthand the importance of balancing external strength with internal support, especially as our bodies change through different life phases.

Jill’s teaching style integrates her diverse movement background, blending precision and alignment with breathwork and mindful practice. She specializes in helping clients discover the power and potential they have in their own bodies, whether they’re recovering from injury, navigating life transitions, or simply wanting to move with more ease and confidence.

When she’s not teaching, you’ll find Jill traveling, exploring nature, and spending time with her family. She’s excited to be part of team grit + tonic.
