Professional coaching for mission-driven individuals and teams

Coaching for social and service sector organizations

Working one-on-one or with a leadership team,  Teresa can help your company create a better future by transforming how you and your team perform your work.


Teresa works with C-suite managers to build upon their strengths and grow necessary capabilities to elevate their executive presence, and have impact on their organization’s stakeholders. We may explore critical factors necessary for success: mission, strategy, business development, people, and execution.


Teresa collaborates with the team leader and team members to improve the human dynamics among the leadership group to meet strategic and operational goals. Clients see increased accountability, better communication among peers, recognition of decision making styles, and experience the joy of making good decisions and empowering their staff.  She supports the leader to give agency to diverse voices in a team, resulting in more innovative solutions.  


One-on-one coaching is available for clients looking for significant progress in their current position (such as a promotion). Teresa also coaches clients to tackle self-limiting beliefs, resolve weaknesses and ameliorate behavior-related concerns identified in performance reviews. In these coaching sessions, we may discuss the client’s family, relationships, finances, health, education, and recreation in addition to professional challenges.
