Melissa Tunzi

Melissa was born and raised in Sonoma County and has lived in Petaluma for over 20 years. She had been in the corporate world for many years and sitting at a desk for hours on end took a toll on her body and mind. She started running and began feeling good about herself again. Beginning to run at an older age and with weight on was hard so she looked for something to compliment her running, that is when she found Pilates. Melissa has been practicing Pilates since 2017. She knew that she wanted to take the next step and share her new found love. She completed Gretchen’s fabulous Teacher Training Program and has put in many hours of teaching, observation, and self practice. Melissa is also certified in BootyBARRE Bounce and teaches Bounce Fusion in addition to Pilates. Look for Melissa on the schedule, she can’t wait to share her passion for fitness with you.
