Our Team

Focus Collegiate provides innovative, hands-on support to equip college students with learning differences for success on campus and beyond.

Our dynamic and professional staff is comprised of Collegiate Life Coordinators, Learning Specialists, Student Skills Specialists, Parent Support, and administrative support. Our students attend their college of choice in the close radius of our Boston area team or virtually around the country. While we do have offices, we often prefer to work with our students on campus or in their preferable locations when possible and virtually went its not.

Our services thrive in major urban centers (and now everywhere) where there is a robust and diverse community providing multiple academic options for our students.

We currently serve college students with learning differences in-person in the greater Boston metro area and around the country through Collegiate Virtual
