Vaz Dera


Vaz Dera is the head coach of CrossFit Crescenta Valley with eight years of experience in the fitness industry under his belt. He started off as a personal trainer at 24 Hour Fitness, where he learned the skills and tools needed to venture out and start CrossFit Array in Montrose in 2011. With the success of his first location, he was able to open his second box CrossFit Array Kenneth Village in 2013.

How did Vaz get into Crossfit? In 2009, during his employment at 24 Hour Fitness Glendale Super Sport, Vaz was first exposed to CrossFit. This experience instantly changed his perception on fitness and he knew he had found something very valuable in regards to training.

Although Vaz thrives on individual training, the community and the group environment is what drove Coach Vaz to change his methodology of training clients. Vaz wanted a create an environment where members walk into the box and feel as if they are part of a family, and that’s exactly what makes Crossfit Crescenta Valley different than many other gyms in Los Angeles.

Vaz’s motivation stems from his clients where he builds strong relationships with them and assists them in reaching their fitness goals. This is what keeps him going and helps him format his gym. His knowledge with personal training allows him to connect to all athletes in his gym whether they are new to the sport, have had injuries and need modifications, or who have experience in the field already. Vaz is the first North Face Mountain Athletics Coach in Los Angeles and has done group training for North Face.

Rubina Vartanians

Rubina was introduced to CrossFit in 2014 during one of her college classes. For the past three years she has been training at CrossFit Crescenta Valley as she implements CrossFit in her every day life.


At the age of three, Rubina enrolled in dance. For twenty one years, she has trained in classical ballet, modern, contemporary, and traditional folk techniques. In 2009, she began to dance professionally and traveled around the United States and internationally to perform in many landmark theaters.


Her love for arts inspired her to study human movement as she obtained a Bachelor's of Science Degree in Kinesiology- Exercise Science from California State University, Northridge. Upon graduating she began to explore the realm of fitness as a mechanism to better herself in and out of the gym. She was drawn to the competitive aspects of CrossFit training. Besides the high physiological demands she began to challenge herself mentally with every workout.


When she is not at the gym, Rubina spends her time teaching, choreographing, and performing. Her passion lies with helping others in achieving what they once believed was impossible. In the near future, she plans to pursue a career in Physical Therapy.
