As college counselors, we have a unique opportunity to help students on their journey of self-discovery and pride ourselves on our welcoming and inclusive approach to college counseling. Being able to help demystify the college admission process and to form close relationships with students and parents is what keeps us so enthusiastic about the work that we do.
Our greatest rewards are in watching students gain self-awareness and confidence and grow in their generosity of spirit and servant-leadership. We know that Potomac has prepared them well to excel as scholars and community members who value lifelong learning and derive pleasure from giving back and creating community.
