Sarah grew up playing Ice Hockey and Lacrosse as a kid.  Since she has been very active with traveling, hiking, and even climbed Mount Kilimanjaro this winter!

Sarah feels that it is important to guide athletes to acknowledge their strengths and build the idea of empowerment with-in.  She became a coach as a way to help others.  For her it is those special moments when the light bulb clicks for the athlete on a particular lift or gymnastics movements.  It is an awesome moment.

When Sarah is not at the gym coaching, she may be found underwater scuba diving!  Come say hi when Sarah is coaching!



Omar Seleiman


  • CrossFit Level 2 Trainer

A little over 6 years ago, Omar was in a rut.  He was not happy with how he looked and felt.  Like so many others, he used to play sports in high school, but as an adult had become very sedentary and out of shape.  So Omar hired a personal trainer.  The work outs were like nothing he ever had done before in his life.  They challenged him and he made unbelievable gains in the his overall strength and the way he felt.  One day Omar asked his personal trainer about the work outs and was told that his personal trainer was certified thru CrossFit.  His personal trainer directed Omar to and Omar was immediately hooked.  He decided right there that he needed to teach others about this transformative program of constantly varied, functional movement at high intensity.

Previous to coming to Brooklyn Omar had taught at a CrossFit box in Florida for two years.  He enjoys helping people meet their goals and help push them harder than they ever knew possible.  His hope is that each one of the athletes he coach will have that same eye awakening moment that he did when he first started.  




  • CrossFit Level 2 Trainer

  • USA Weightlifting Level 1 Coach

  • Freestyle Connection Movement Attendee

A former college soccer player, Jes moved to Brooklyn in 2009 to get her Master’s at Pratt Institute.  After dedicating the first 20 years or so of her life to athletics, the 5 or so years after college became more about becoming an architect, deciding who she was, and finding her place in the world.  While beginning to answer some of these questions she also put on about 15 lbs and was just disappointed in how she felt.  Luckily Jes found CrossFit through some friends – who never stopped talking about it.  Thanks to them she feels better than ever.  Jes got certified to be a coach in the Summer of 2011 and can’t get enough.  She love the ongoing challenge, the comradery, and the results.

When not at the gym, Jes love to cook, be outside, and play with her amazing dog Cash.

Alissa Gordon


  • CrossFit Level 2 Trainer

  • CrossFit Gymnastics Trainer

  • USA Weightlifting Level 1 Coach

  • Precision Nutrition Level 1 Specialist

Alissa discovered CrossFit in 2011 while living in Washington, DC. After playing Division 3 field hockey and lacrosse in college, Alissa struggled to stay in shape without a team surrounding her. When she walked into CrossFit MPH in 2011, she was out of shape and overweight, and had never done a pull-up or touched a barbell before. She instantly loved the community she found with CrossFit, and the balance it brought to her professional life and overall happiness as a human being.

In 2012, Alissa started coaching at CrossFit MPH, and after moving to Brooklyn in June 2019, she is very excited to be coaching at Crow Hill. In addition to coaching, Alissa has been judging at The CrossFit Games since 2015, and has also competed at USA Weightlifting Masters Nationals. When she is not at the gym or her daytime job in tech, you can usually find her with her zoo of animals--Dexter the French Bulldog, Lilly the rescue pup, and Maeby the former street cat.
