Agatha 'Aggie' Johnson


Agatha Johnson, known for being intuitive regarding people, is founder and owner of Will Kate, an organization focused on the purpose of your family wealth.

Aggie has years of experience working with clients who desire and value trusted expert wealth advice and advising them on how to be successful in life by finding the financial freedom to accomplish their purpose and dreams. She cares about each client’s personal success and takes the time to get to know the families and organizations she works with on a personal level. Aggie has worked with a wide range of clients, from families in business and high income earners, to medium-to-high net worth clients and ultra-net worth clients.

After decades working with individuals, families, and businesses, Aggie realized that most people focus on two specific areas of wealth planning, financial decisions and estate planning, which causes many to struggle with their choices. Aggie’s approach looks at the bigger picture; her expertise is in helping clients adapt to wealth, understand their relationship with wealth, and realize their purpose and vision. This creates the foundation for experiencing a greater opportunity to achieve dreams and lasting effects for different stages in life and future generations.

Agatha’s multi-disciplined approach provides guidance in six dimensions of wealth: financial, spiritual, human, family, structural (how things are owned and used) and societal. She helps clients define the opportunities they wish to create for themselves, family members, people, causes, and communities for which they care. Aggie has used this approach to work through many scenarios of opposing dynamics which can often times create complexities and complications. She believes having a strong path will provide the opportunity for lasting legacies.

Agatha is married to Craig, has four grown sons, three wonderful daughter-in-law’s and seven beautiful grandchildren.  When not working with her family of clients she can be found enjoying time with her family, traveling with her husband, hiking and giving back to the community.
