What drives me is the high level of responsibility, joint excitement and the trust that our customers place in us. The professionalism and personal connection that can develop between Entrix and our customers is what excites me. At Entrix, Portfolio Management is responsible for all customers that generate revenue — our communication and actions have a true impact on the success of our partnerships and both of our companies.

I believe in extreme ownership, clear responsibility, and having each other's back. A growth mindset, trust, integrity and open communications are the principles I lead by. My goal is to create a team where everyone feels empowered to develop and thrive.

If you’re passionate about driving meaningful change in the energy space and contribute to our joint success in a dynamic environment, we’d be thrilled to have you on board.

Let’s make the energy transition real—together.

Best regards,
Anton
