Certified Scrum Trainer & Agile Fellow

I'm an Agile Fellow with Rally Software in Boulder, CO. I love coaching others about Agile software development. My passion in this realm has led me to concentrate on practices in collaboration and leadership. I'm also now reaching into systems thinking, Lean, and Kanban (you can read blog posts I've written about these topics). I see a strong interdependency among these various processes and practices. This has led me to also look outside of software and IT to our larger community about sustainable and restorative practices within our physical world.

I graduated Magna Cum Laude and as a University Scholar from the University of Missouri. I hold a Masters in French Literature from Michigan State University and a Masters in Computer Science from Johns Hopkins University.

Agile Coach, Certified Scrum Master, Certified Scrum Practitioner, PMP

Christen is an Agile Coach with Rally Software in Denver, CO. After seeing a need for better software at United Airlines reservations, she left to begin her IT career in 1996 as a Business Analyst with Airline Tariff Publishing Company and continued to grow her career in Systems Analysis, Project Management and Program Management at AOL.

She was so convinced, after getting her CSM in 2006, that agile was that “special sauce” for building great teams, that she voluntarily began offering a simple Scrum class to anyone in the company that wanted to learn. This caught the attention of Technology leaders, and she was asked to integrate agile techniques and practices into the traditional waterfall SDLC model across the globe at AOL. This transition led to their interest in full adoption of agile in 2007 and a large re-investment in training and coaching in 2011.

Christen has over decades of experience in a variety of roles and environments and is passionate about using Agile methods to help guide teams in the implementation of quality products and deliverables that would stand out as successful examples to other teams and encourage Agile practices at an organizational level. She brings a unique combination of coaching at the team, manager and executive levels to reinforce their roles and how they are each responsible for the success of Agile.
