  • Crucial Conversations vs Critical Conversations
  • Strategic Self Discovery
  • And Much More
Coaching & Mentoring:

Our instructors often take on personal coaching clients. When they do, an individualized plan of action is co-developed with the coaching client with the intent of growth both in self and as a leader. We will soon add a master’s class and coaching groups to allow for exchange among LHLN members. It is through dialoguing with our peers that some of the best learning occurs.
