Diana Zackey, MD

Primary Care Physician in Philadelphia, PA

I’m the daughter of two public school teachers, who taught Latin and English literature, and I grew up in central Pennsylvania, near Lancaster. I went to Yale for college and studied English myself, only to realize after working for two magazines and a small publishing house that I wanted to have a greater positive impact on the world and my community. I decided to do a post-baccalaureate program at the Harvard Extension School in Boston, studying all the necessary prerequisites for medical school. While I applied to medical school I worked as a research coordinator for a group at UCSF studying dementia, and in my spare time I waited tables at a restaurant. I had the chance to go to Tulane for medical school, which to me was an opportunity to explore the South and dig into New Orleans culture. After surviving medical school I was ready to come back to the northeast, and I completed my internal medicine residency at Cooper, in Camden. I currently live in West Philly where I love to grow fruits and vegetables in my garden, cook, grill, and ride my bicycle. I’m very excited to be joining the Ninth Street group and to build new relationships and improve our health together.

COVID-19 Vaccine

We are pleased to announce that NSIM is partnering with Centennial Pharmacy Services to administer COVID vaccine shots in our office. We have worked closely with Centennial Pharmacy Services for many years and they are a trusted partner.

We do not know when our first doses of vaccine will arrive nor do we know how many doses we will get on a weekly basis. The number of people who want the vaccine is far greater than the supply Philadelphia receives weekly from the federal government.  We are following the Philadelphia Health Department prioritization phases in administering the vaccine. We anticipate it will take at least until the end of May or longer before the city has vaccinated all people over 65, those with chronic medical conditions, and those working in occupations essential to our economy.

If you want to receive the vaccine in our office when we receive a supply:

Register your interest

You will complete and submit a questionnaire. The information you submit is confidential and the only people who have access to it are the staff of NSIM and Centennial Pharmacy. It will be used only for the purpose of COVID vaccine administration and not for any marketing purposes or sold to any other entity. Once we know that we are receiving the vaccine, you will be contacted about an appointment time by Centennial Pharmacy either by text message, email, or phone (depending on your contact preference).


If you have any concerns about the safety, effectiveness, rapidity of development or other issues regarding the COVID vaccines, please contact your primary care provider at NSIM.

Please be patient. No one will be truly safe until everyone in our country who desires the vaccine has received it.  Please continue to wear your mask when outside of your home, maintain social distance, wash your hands, and follow other guidelines from the health department and CDC. Once you receive the vaccine, you will need to strictly maintain these precautions at all times until our public health officials tell us otherwise.
