Seabury Hall announced the appointment of alumna and former trustee Kaimana Lee Brummel as the new Director of Advancement. The Director of Advancement is responsible for overseeing the school’s fundraising, marketing and communications, which includes managing alumni and parent relations, the annual fund, major and planned gifts, special events, strategic communications, public relations and publications.

Kaimana will serve on the school’s leadership team and will work closely with the Board of Trustees, Head of School, faculty and staff to achieve Seabury Hall’s strategic goals.

“We are delighted to have Kaimana lead the Advancement team,” said Maureen Madden, Head of School. “As a trustee of Seabury Hall, Kaimana has left an impression that was hard to ignore. She will bring strong and thoughtful leadership as well as a deep passion for our school. As we move forward, Kaimana will be a valuable partner to me and the leadership team for Seabury Hall’s continued growth and success. I look forward to what we will accomplish together for Seabury Hall.”

Kaimana’s appointment follows the resignation of Kimberly Castelo, who is leaving the school to forge a new career path. Castelo is credited with integrating Seabury Hall’s development, marketing and communications under one department.

“I’m proud of the work I have accomplished with the Advancement team and I look forward to seeing the exciting new programs and initiatives to come, especially with Kaimana’s leadership,” said Castelo. “Seabury Hall is a warm and supportive community and I will remember my time here fondly. I wish Kaimana every success in her new role.”


Brummel brings knowledge and experience from the nonprofit sector as well as expertise in marketing and public relations. In her previous role as Community Engagement Lead of Blue Zones Project Maui, Brummel and her team engaged more than 17,000 Maui residents through more than 200 events, activities and partnerships. The program was successful in registering 50 organizations to be involved in making healthy changes in their business, schools, restaurants, grocery stores and non-profit organizations. In June, Brummel was named Pacific Business News “40 Under 40,” an annual award honoring outstanding young business professionals in Hawaiʻi.


The appointment follows Brummel’s decade long service to Seabury Hall as a volunteer in various roles ranging from volleyball and canoe paddling coach, president of the Alumni Association, chair of the Seabury Hall Golf Tournament, and most recently as a member of the board of trustees.

“I am honored and excited to be joining the Seabury Hall team in this new capacity under Maureen Madden’s leadership,” said Brummel. “I look forward to working with alumni, families and friends of Seabury Hall to build on a strong tradition of philanthropy and share the school’s innovative programs and traditions with the broader Maui community.”

Born and raised on Maui, Brummel graduated from Seabury Hall in 2003. A fluent Hawaiian language speaker, Brummel attended Kula Kaiapuni o Maui Hawaiian language immersion school before entering Seabury Hall in the ninth grade. A D-I volleyball scholarship took her to Washington, DC where she attended The George Washington University and double-majored in International Affairs and Geography.


Brummel and her husband Aaron have two children. They love the beach, playing sports and spending time together as a family. An active community volunteer, Brummel is a strong advocate for causes related to children, education and the environment.
