Nicole Priest

Nicole is very excited to be a part of the family at Vision Plus Fitness as a yoga teacher at LOVE! She began practicing yoga towards the end of the college and fell in love in the practice over time. Yoga has provided her many tools to help her navigate life’s challenges and remain grounded. Living a very fast-paced lifestyle, she finds that the most important lesson yoga taught her, was how to slow down.

Her favorite way to spend free time is being with friends, going to the beach, cheering on Philadelphia sports, and of course any possible to keep active and moving (except for mountain climbers). As an instructor, she hopes to provide others a safe space to show up, slow down, and be exactly as they are. She loves meeting and connecting with new people and cannot wait to see you on the mat!
