Ericca Z:

My favorite thing about StemExpress (aside from our noble mission) is the leadership. Our leads and managers care about employees and are always willing to teach. Each employee is valued by their supervisor and this creates a culture that emphasizes employee development. When I was new, all leads were pivotal in teaching me something new about our company (I’m still learning to this day!). My favorite perk about working in headquarters is working in a dog-friendly office; canine visitors are always welcomed with doggie bones and unlimited pets!

Emma B:

I enjoy working at StemExpress for a multitude of reasons. I truly see the I CAN DO attitude in everyone and the drive is contagious. One thing that really stands out though is how open communication is between all employees. Because I work remotely and am not in the office everyday it can be difficult to remain in close contact with my coworkers. However, at StemExpress I know I can call my team up at any time and they will help me out. Matt does a great job of keeping me in the loop and I know I can always count on the other employees to help me out if I need help (even from the other end of the state or country). Along with this, when I am able to come into the office everyone is so kind and treats me as if I am physically there every day. It’s a very inclusive team and we all want each other to succeed.
