About Athenæum Advisory

At Athenaeum Advisory, I help both families and schools navigate admissions with clarity, confidence, and a personal touch.

For Students & Families

I guide families in finding the right schools or programs for each child, helping them craft compelling applications, manage timelines, and prepare for interviews — all while making the process feel manageable and even enjoyable.

For Schools & Institutions

I partner with schools to optimize admissions strategy, messaging, and family engagement. Drawing on my experience in enrollment management, advancement, and communications, I help institutions attract the right students, refine outreach, and build lasting relationships with families.

Approach

Whether guiding a student through private school, college, or specialized program admissions — or helping a school refine its enrollment strategy — my approach is clear, ethical, and collaborative. My goal is always the same: to ensure students and schools find the best fit, and to make the admissions journey a positive, purposeful experience.
