I had my first class at IFP with Marianne. I've had classes with Marianne at another studio. First, Marianne is a wonderful teacher. Although she teaches a class with others, she will provide individualized attention to each person. She is so warm and kind. I can't recommend her enough! Second, I love the feel of this studio. It's has a calm feel to it. The reformers are also amazing. 5 stars all around! Can't wait to come back.

Jackson is a wonderful instructor, he helps you to focus on what is taking place in your body while giving fantastic instruction and guidance on the movement task at hand. Times well and deliberate, one can deepen their movement practice. Thank you for the experience!

Sharon is the best there is! She has healed my body…. Even after extensive work with a PT. This is not all about Pilates, it is about her fantastic knowledge about how the body works and her ability to release the aches and pains. I am working on my husband to come and work with her… Pilates is not just for women and Sharon is really really special! ( I thought I had posted this months ago!)
Oh, and my husband did come in— finally!—and now is a total devotee! He has done acupuncture for over a year, but will now not miss a week without Sharon! Life is improving…

I LOVE Danielle Hendriks' online Pilates class on Tuesdays at 10:00am PT. She takes the time to explain details, responds to questions/concerns after class, challenges us with new ways of doing the exercises. Her amazing aerial and dance backgrounds add to the class! Couldn't be happier! It's an amazing workout.

I've had the pleasure of taking several virtual classes with Brooke Notary. Brooke's energy keeps things fun; she gives such great verbal cues to help a Pilates beginner like me understand how to perform the moves effectively and safely. I can immediately feel the tension melting away and feel so amazing after class. It's been such a great complement to my conditioning and weight training. I'll be back for more!

I love attending virtual classes at this studio! Brooke Notary's Mat class, taught in the style of Pilates elder Kathy Grant, was fun, playful, and expertly taught with a side of sass that would make KG herself proud. Every class I have taken here has been attended by other teachers from the studio. It is a beautiful learning community that owner Sharon Gallagher-Riviera has created here.

I love Dani' Hendricks' history with Kathy Grant and the way she describes what we're supposed to be doing. She incorporates household and functional props to keep things interesting. If you can't see her in person, virtual is the next best thing.

This studio has the best teachers around. I just took my second class with Darien Gold. She is amazing. I have been teaching for 25 years and studied with many first and second generation teachers. She is one of the best teachers that I have ever had the pleasure of studying with. Darien is a crazy mix of patient and demanding, never settling for less than she thinks that you can do. Sharon Gallagher-Rivera is also a top notch teacher as are all of her amazing staff. You really can't go wrong here.

Great intimate studio. Have taken classes with several teachers but felt Jackson has spent the most time tailoring the workouts for me. And on the plus side I actually leave pretty sweaty. Because of his coaching I took a curiosity in pilates to coming twice a week. I've been especially pleased with how much this practice has helped out with my weak lower back. Most of my daily pain is gone! If you are curious too, I'd try a starter pack and prepare to join full time;).

Sharon is a fantastic pilates instructor! She has helped me so much in correcting my posture, building general strength and developing a deep understanding of the body. I cannot recommend her more.

You simply won't find a better pilates studio in Marin - or the entire Bay Area, honestly. The instructors here are incredibly trained and really know their stuff. You will leave feeling amazing - your whole body will feel like it's worked, you'll walk a little taller. I've taken both one-on-one privates as well as group classes and love it all!

Feeling so grateful right now for Kerry O'Keefe at Internal Fire Pilates. My high schooler has struggled with foot/ankle/leg pain since 4th grade -- she has extremely flat feet and has injured her feet and ankles numerous times. We've spent years taking her to podiatrists and physical therapists, but nothing has made much of a difference. Finally, a friend suggested we try Pilates, and recommended Internal Fire. Within a few weeks she was markedly better, and six months later, she is walking like a different person -- no limping, no pain. We can't say enough good things about Kerry. She is always enthusiastic -- obvious she likes her job -- and sincerely encouraging. From the get-go, my daughter -- who was hesitant about trying Pilates -- has felt very comfortable with her. She has a warm manner and explains everything she does well, so that it makes sense. So my daughter looks forward to her sessions, and is much better for them. Very thankful!
