OWEN BITAS
Coach, CrossFit Hierarchy
  • CrossFit Level 1 Certified

A lifelong athlete, Owen discovered CrossFit while searching for a way to get back in shape after recovering from an injury and illness that derailed his collegiate football career. His passion for Olympic Lifting initially drew him to CrossFit, but it was the realization that CrossFit was a tool for improving yourself both inside and outside the gym, and not just another training program, that made him stay. He endeavors to make sure athletes realize that they have potential far beyond what they believe they have, and he will probably always be more excited about your PR than you will be. He loves clean and jerks and hates cucumbers.

ROB BLACK
Coach, CrossFit Hierarchy
  • CrossFit Level 1 Certified

Rob grew up wandering around the vernal pools of New England and learning how not lose some finger to turtle bites. In college, he worked hard on pulling a stick through the water and captained the rowing team his senior year. He has been working at CrossFit since March of 2015 and sees coaching as an amazing way to pass along that passion for hard work. He loves 80's action movies and hates very little...it leads to the dark side. But veggie burgers are on that list.

SARA OLIVERI
Yoga Instructor
  • Registered Yoga Teacher
  • Yoga Fit Certified
  • Certified Personal Trainer
  • AFAA Group Fitness Instructor

Sara has been teaching yoga for almost 9 years and doing CrossFit for about one year. What she loves most about yoga is how she feels flexible and free in her body, but also clear-minded and happier after. For Sara, yoga and CrossFit are a perfect combo. CrossFit has made her stronger, and yoga has made her more self-aware, mobile, and aligned. Yoga enables her to approach CrossFit healthily, execute better form, and avoid injury. It also helps her to calm the fuck down and not sweat the small stuff. She loves burpees and hates sea urchin.
