Back to Team

Sean became a technologist because he saw the potential for computers to change business environment.  He has focused on helping companies simplify the complex so that they can efficiently find new ways to help their customers. 

Sean started his career in the management consulting world at Andersen Consulting (now Accenture) helping local and long distance telecommunications companies compete as cellular became prevalent.  Next he focused on using the Internet to enable collaboration and workflow in knowledge work like new drug applications and mortgage processing.  He then helped grow a financial technology startup into a world-wide operation with over 500 employees. 

Sean joined Cuesta Partners in order to continue to help companies be successful as they grow.  He enjoys seeing teams succeed as they face new challenges.  Recently, Sean has helped companies patent new technologies, grow and find good leaders, establish new technology strategies, cut costs, sell divisions, and win software lawsuits.

Sean lives in Chicago with his wife and 3 teenagers.  You can regularly find him experimenting in the kitchen or tinkering with Open Source software.
