Am I a leader?

Parents, therapists, health care providers, solo entrepreneurs, sports coaches, consultants, mentors, partners in a relationship, teachers, authors, and others who interact with people regularly are all leaders.

Executive Leadership

Having someone in your life who listens to you completely without judgment and without trying to fix you is truly valuable. Discussing internal contemplations, such as choosing between doing what is expected from you and what you want to do is important to align your personal goals and priorities. 

Custom Workshops

Diane is your champion, your advocate, and your honest source of objective feedback. She will listen objectively and help you customize the approach that is needed to help you unlock the answers you need.

Mind-Body Connection

Your brain and body are connected. Your routines contribute greatly to what you can accomplish in any given day. What you eat, your physical fitness, and your attitude are all important components in your plan for success.

Leadership Development

Diane has partnered with Academy Leadership, LLC in the Kansas City metro area to deliver impactful programs to transform leaders to the next level of effectiveness, optimizing their influence and performance.

Developing This Trait in Others

Diane is passionate about empowering people to lead and live purposefully and joyfully. Turning knowledge into action equips these individuals to achieve their goals, define their success, and feel fully satisfied both professionally and personally.

Empowered and engaged leaders prioritize their day to focus on the most important things — being proactive, responsive, and reflective in real-time and of the future — so that they can hone their influence and effectiveness. Diane encourages people to be “all in” to further their development and growth.
