“Nothing has ever been accomplished in any walk of life without enthusiasm, without motivation, and without perseverance” – Jim Valvano

I am originally from Stony Brook, New York, and I attended St. Anthony’s High School in South Huntington. I completed my undergraduate education at Bucknell University in Pennsylvania, where I also competed in track & field. After graduating from Bucknell, I returned to Long Island to earn my Doctorate in Physical Therapy from Stony Brook University.

While completing my education, I have worked as a Physical Therapy Aide at multiple outpatient clinics on Long Island. I have also completed four clinical rotations in both acute care and outpatient orthopedic settings.

Core Values:

Some of the core values that drive me include humility, integrity, and compassion for others.

When dealing with injuries, aches, and pains, we can quickly lose sight of the things that we truly enjoy doing. I want to help patients regain confidence in movement, rebuild strength, and get back to the activities they love.

As a recent graduate, I am excited to join the team at Greiner PT as a physical therapist in the new Quogue location.

I enjoy treating a variety of orthopedic conditions, especially those related to hip and shoulder pathologies.

I love the team-oriented environment and commitment to quality care that everyone at Greiner PT exhibits.
