I am a coach and consultant in the Agile space, helping large and small organizations navigate their enterprise Agile adoptions and transformations. I’m also a professional coach, certified in integral coaching. I have been teaching and mentoring Agile practices for about 8 years, teaching many hundreds of people along the way, and all around the world. I’ve coached dozens of teams through the ups and downs of their Agile journey, many of them in Fortune 100 companies. I create and lead workshops and practice cohorts for leadership development, and I’m passionate about helping leaders of all levels learn how to lead in a way that generates learning in their organizations. I have deep training in systemic coaching, and I bring this to bear in my interactions as a teacher, facilitator and enterprise agile coach. Working with some of the largest Agile companies, I am a practiced facilitator for team events and trainings ranging from a few to 300 people. My deepest fulfillment comes from providing an environment where people can discover their own competence to better navigate their life and career.

Simon Macpherson

I am passionate about helping individuals, teams, and organizations discover how to maximize value from applying Agile principles.  As an Agile Coach I seek clarity around; purpose, sharing the vision, and the personal values needed to align towards achievement, innovation, and sustainability.

I am also a pragmatist who understands, through experience, this is a journey for both the organization and each individual. How can Agile methods and mindset work in the existing container? What do we need to work on to change the environment to support greater agility? And ultimately, understand this is all about you. How are you showing up, what change is also needed in you? Because, here is the rub, trying to change others is futile but we have full control over changing ourselves.

My work life experience stretches across a variety of backgrounds beginning in retail, moving toward manufacturing and engineering, a stint in self-employment, many years in the hospitality industry, and finally software development. As an Agile Coach I have long term practice in telecommunications, health-care, travel & leisure, and insurance. I am also a trained and practicing Co-Active Coach.

Tim Cunnane

As an Agile Coach and faculty member of the Agile Coaching Institute, my passion is catalyzing the excellence that individuals and organizations contain. Through coaching, facilitation, teaching, and consulting, I have helped dozens of organizations develop highly-collaborative and effective leaders and teams. I leverage core values of curiosity, transparency, and dialogue to help people self-define and achieve ever-higher levels of performance and purpose. In addition to Agile Coaching, I am a student and practitioner of Integral Coaching. This methodology of professional coaching draws upon many traditions—biology, cognitive science, linguistics, philosophy, psychology, spirituality and more—to provide many avenues of insight and practice. My work with this methodology highly influences my approach to Agile coaching. Though different, I find the focus on long-term excellence and building the capabilities of self-correction and self-generation within individuals to be cornerstones of my work as an Agile coach.
