Vernon Centers "Chase Brexton brings together many of the areas that have shaped my career-- HIV, sexual health, LGBTQ+ health, and health equity. My professional experience in these areas has given me a strong understanding of the unique needs and barriers many of our patients face. I'm excited to bring that perspective into patient care, build trust, and provide care that is comprehensive, inclusive, and meaningful." ![A headshot of Jack Pollack.](/sites/default/files/styles/large/public/2026-09/Pollack_Jack_2026.jpg.webp?itok=heN63r81) #### Jack Pollack, MD Staff Physician, Mt. Vernon Center "I came to Chase Brexton because they are a community health center committed to providing high-quality care to anybody who needs it. As I learn more about Chase Brexton, I am impressed by not just the excellent medical care at their centers, but also by the range of services they provide to help patients get and stay healthy. I'm excited to join the team! My background is in community health, and as a family medicine physician I provide primary care to adults and children. I have a special interest in addiction medicine and look forward to getting started in the clinic!" ![A headshot of Dr. Sarah Sheikh.](/sites/default/files/styles/large/public/2026-09/2026-Sheikh_Sarah.jpg.webp?itok=TTjUbx8Z) #### Sarah Sheik, DO, FACOG Staff Physician, Security Square Center ## Media Inquiry Daniel McEvily, Assistant Vice President of Marketing and Communications [1-667-354-0722](tel:1-667-354-0722) Aaron Cahall, Communications Manager [1-667-354-0725](tel:1-667-354-0725)
