Our Consultants

TNG manages the membership associations NABITA and ATIXA. Each consultant is identified by their role within each organization.

What is our competitive edge? Content, trainings, and consulting in this field are probably 80% alike, but a 20% margin has always differentiated TNG and creates better results for our clients. Our 20% value add results from being incredible listeners and unorthodox problem solvers who often reject the premise that something can’t be done. We are adept at working within a client’s current culture, or helping them to change it based on our detailed understanding of all the moving parts of a complex organization, all while helping to advance decisions that empower the client to manage risk effectively.
