Current Clients
After moving to Colorado’s Front Range in the summer of 2025, Karl is establishing Walker Court Associates as a Colorado-based company and will be able to take on new clients in the September of 2025.
Past Clients
The ACMG Foundation for Genetic and Genomic Medicine (2019 - 2025)
Walker Court Associates was retained by the ACMG Foundation for Genetic and Genomic Medicine in February of 2019 to support its first CEO transition. The ACMG Foundation is the nonprofit fundraising arm of the American College of Medical Genetics and Genomics (ACMG).
Karl worked with Board members and the ACMG’s founding Executive Director to retain past donors and ensure a smooth transition to the organization’s new CEO. Karl then worked with the Foundation Board, the inaugural CEO (Dr. Maximilian Muenke), and senior staff members to strategically enhance the organization’s fundraising capacity, database systems, and grant and program areas. Karl also organized a CEO “listening tour” to California where he and Max met with a dozen leading companies and academics during a week-long visit to several cities. He also led the launch of a new Evidence Based Guidelines Program (press release here) and supported other functions of the organization as needed.
In 2022, Karl was invited to become a staff member of the ACMG Foundation. Soon after, Dr. Bob Best, a Founding Fellow of the ACMG, became interim CEO upon Dr. Muenke’s retirement. Karl again helped with continuity during this time of change. Staff member Melanie Wells, ACMG’s former COO, was then selected to take over the CEO role after the 2023 Annual Meeting. Karl again organized trips to California and New York City so that Ms. Wells could meet with nearly a dozen corporate partners and other senior donors. Face to face meetings were also organized in the metropolitan DC area, and during the 2024 and 2025 Annual Meetings.
After more than six years of service to the organization and to four senior executives as both a consultant and staff member, Mr. Moeller tendered his resignation in the summer of 2025 after moving his permanent residence to Colorado. He is particularly proud of the $5.7 million he raised in support of ACMG’s programs, of the Corporate Partner Program he established, and of his work to professionalize the development program and advance the organization’s evidence-based guidelines initiative.
Scientific Technologies Corporation (2014 - 2018)
This Arizona-based public health software company first hired Karl to serve as a consultant and Advisor to the STC Board under the Walker Court banner. After a year of consulting, STC hired him as their first-ever Vice President where he led a growing team and greatly expanded public sector sales.
TAPI – The Arizona Partnership for Immunizations (2014)
Karl partnered with his colleague and public health specialist, Dr. Bruce Rusio, to publish a policy paper for TAPI’s Board. The research paper focused on the Affordable Care Act and its impact on national immunization policies.
CPH and the Campaign for Public Health Foundation (2004 - 2014)
After opening his own consulting business, Karl’s first client (2004) was the Campaign for Public Health. By the end of 2005, CPH’s C-suite Board of Directors hired Karl full-time. Ten years later, both CPH and the CPH Foundation were moved under the banner of Walker Court Associates during a transitional year. As a consultant and employee, Karl worked with the board, staff, volunteers, and many partner organization to advance public health and the Centers for Disease Control and Prevention for a decade. External changes in Washington’s political leadership led the organization to close, but dormant Facebook pages for both nonprofits can still be found through the hyperlinks above. Here, readers can get a sense of the programs and goals that Karl advanced through these high-profile public health advocacy and educational organizations.
And 400 Other Clients (2017 - 2020)
Under the banner of Walker Court Associates, Karl turned a historic carriage house in Washington, DC’s Capitol Hill neighborhood into a boutique apartment building. Once construction was complete, Karl rented the two new apartments and hosted 400-plus visitors over two-plus years. More than 95 percent of his guests provided 5 star ratings, gaining him Airbnb’s elite “Airbnb Plus” and “Superhost” titles. He sold the building privately in January of 2020 for more than twice his initial investment.
