OUR INSTRUCTORS

Allison Villegas (Owner)

Before opening Windsor Fitness Club, I started my fitness journey as a dancer. I danced competitively from when I was a child and into my adulthood. As I got older, I realized that I needed something else to deliver a fuller body workout, while still maintaining my flexibility. That’s when I discovered Pilates. Taking group Pilates classes made me feel so amazing! Not only did it transform my body, but my energy and confidence increased as well. Needless to say, I was hooked! Six months later, I got certified and was teaching my own classes! Now I have been an instructor for over 7 years. What I love about teaching Pilates is challenging individuals at their own levels while watching them improve and grow. I am a major fitness advocate for all walks of life. Live fit, feel fit, be fit!

Renée Miron

Renée brings 10 years of experience in fitness and movement, along with a genuine love of coaching people in a room together. A NASM-certified trainer, Corrective Exercise Specialist, and group fitness instructor for the past decade, she previously built and ran her own group fitness business in Sonoma County before stepping back to raise her two children. She is glad to be back on the studio floor.

Her classes are built around functional movement, focusing on how you bend, lift, stabilize, and move through daily life, with an emphasis on mobility, balance, and lasting capability. Expect dynamic sessions that may draw on strength work, HIIT, calisthenics, and Pilates, paired with upbeat playlists and a supportive atmosphere. Renée thrives on the camaraderie and accountability of group fitness: the energy that helps people push a little further and leave moving better than they walked in.

My name is Carlos Mendoza. I’m originally from El Salvador, but moved to Santa Rosa from Reno recently. I’m a father of a beautiful 23 year old daughter and an awesome 19 year old son. I’m a former amateur boxer and boxed for 12 years. I have been a student of the sport since turning the fire off at 24. I’ve since been a Pilates instructor for the last 6 years, a personal boxing coach the last 4 and a fitness junkie all my life, whether I liked it or not! I love hot Pilates because this work out changed my life and the way I look at fitness! I also teach yoga, boxing and I’m super excited to work with all you and share my crazy energy and love for fitness. Much love! Let’s Get It!!

Jessica McMillan

I started my training in dance, but soon my interests turned to yoga. Yoga created an avenue of self-reflection and deepening into the body like no other. I have been practicing yoga since 2009 and got my 200hr YTT in 2014. Since then, I have taken advanced Anna Forest training, been a practitioner of Ayurveda, and developed an extensive understanding of the muscles and movement of the body through massage therapy. All this knowledge has been integrated into my practice and has helped me to be intentional and intuitive with my touch. Yoga is the perfect start if you want to strengthen your connection with yourself while gaining balance and strength!

Vanessa Selzer

I started practicing Pilates in 2017 and was instantly amazed by how it brought clarity and lightness to my body and mind. In 2019, I began teaching! Pilates is my lifeline. It’s not just a workout, it’s a system of support for growth and transformation. Every time I see someone accomplish their goals, I appreciate the great reward of being part of their fitness journey!

Paulette Marshall

My name is Paulette Marshall, born and raised in San Jose but moved to beautiful Sonoma County in 2013 with my husband. I’m a mom of two young kiddos and have been an avid fitness lover most of my life. I grew up doing dance and playing softball, finally finding my way into the gym when I was 18 and found strength training as an outlet that I loved! After having my second child I noticed how my body wasn’t responding to traditional workouts anymore. I dove deep into postpartum recovery, the importance of our breath and rehabilitating my body from the inside out. This ultimately lead me to pilates at Windsor Fitness Club and I once again found an outlet that was exactly what I was looking for! The heat, focus on our core & deep abdominals as well as the motivation inside of a group fitness class inspired me to continue my research and complete my ACE GFI certification. Strength training is what I love especially when emphasizing the importance of our mind / muscle connection. Health and wellness is a lifestyle and fitness is major part of that, ultimately my goal is to inspire others during their individual fitness journey!

Kate Remsen

Kate began her yoga practice in Los Angeles, CA in 2010 and quickly realized that yoga was not only for the body but also for the mind. Coming from a chaotic mental state, yoga helped guide her on the path to her truest self. Now, yoga has become a way to harness the strength within; building from the core, or third chakra, and expanding outwards. Kate has a background in Power Yoga and has modified her teachings to include both strength building and restorative poses, creating a balanced body and mind connection.

I have been involved in the fitness industry for the past 30 years and have always loved teaching and the energy created in the actual instruction of each class.

Hartlyn Ower

I was born and raised in Petaluma and love this community dearly. I am so grateful to be raising my own family here. I have a passion for Health and Fitness that began after having children; my health and overall wellness suffered from low activity, chronic stress, postpartum complications, and an ignorance of how to care for my body, mind, soul, and spirit. After finding so much healing and freedom through movement, I feel enthusiastic about partnering with others on their own wellness journeys. I am a SRJC alumni with two ACE (American Council on Exercise) certifications in Heath Coaching and Group Fitness along with a certification in UpBeat Lift. When not at the studio, you can find me at the dog park with my Bernese, petaling around Petaluma on my beach cruiser bike, or in the bleachers cheering for my kids sports teams!

Fitness has always been at my core. Muscles are so beautiful. Breath work keeps the mind and body present. Born and raised in Petaluma, I now raise my three strong, beautiful girls with my biggest supporter and fan, my husband Simon. I love to cultivate community on and off the mat. Let’s ground down as one so we can move our bodies in unison. Let’s ignite the fire within to burn away what is no longer needed. Let’s synchronize our breath to cultivate long lasting results. I invite you to move with me
