Disney XD's Lab Rats Wiki

This cast member won favorite cast member in the 2014 Lab Rats Wiki Awards!

The end of an era...It was a painful realization for me to come to. These people have been my family for the past 5 years of my life. Saying goodbye to them was one of the hardest things I've ever had to do. I grew up on this show. I learned a lot. I was shown absolute love and encouragement from people who believed in me and reminded me of all that I was capable of. All that is left of it now are my memories, friendships & the 98 episodes we filmed over the course of 4 seasons. I am forever grateful to the cast, the crew, our incredible show creators/producers, the writing staff & everyone else who contributed to making these precious years so unforgettable. I love you all. - Lab Rats (2011-2015)
