I found yoga in college after playing sports my entire life. When I got into college I felt like I was missing something, and through yoga I slowly started to figure out I missed spending time with a like minded community, a team that I could move with, sweat with, breath with, and spend time dedicating moving my body with. I was never that competitive, but I loved the feeling that came from being on a team; the sense of pride felt from working together to accomplish something bigger than the self, the trust and collaboration that builds from spending time practicing, and the individual spirit that develops from supporting and putting faith in one another. Yoga gave me this feeling again, and I quickly began to fall in love with the practice. When I moved home from college in 2012, I knew I wanted to make Yoga a permanent part of my life, so I took Yoga Teacher Training at Corepower in Berkley and have been teaching ever since. My passion is sharing yoga with people that may not otherwise do it: people that think they’re too old or young to start, athletes that think they ‘stretch’ enough, professionals that don’t think they have enough time to practice. Because the truth is practicing Yoga is for everyone. It’s a time to give yourself permission to breath, to move, and to realign with your needs of the day. In this fast paced world we all need to practice reconnecting with ourselves so we can better connect, collaborate, support and love one another like teammates.
