Center for Key Populations
Center For Key Populations Banner


To ensure that every patient at CHC receives comprehensive care in a respectful manner within a safe environment.


To guarantee that key populations in the communities we serve have a central and cohesive focus within CHC.

The Center for Key Populations recognizes five key groups who carry the highest burden of and risk for HIV infection: men who have sex with men, transgender people, people who inject drugs, people in prison, and sex workers. These populations experience many barriers to healthcare and, in addition to HIV, are disproportionately affected by Hepatitis C (HCV), sexually transmitted infections (STIs), substance abuse, and many other co-morbidities. The Center will ensure access to integrated, evidence-based quality specialty and primary care to all patients through the integral collaboration and utilization of the vast and rich resources available at CHC including:

·          World-class clinical care

·          Quality improvement

·          Training and education of the next generation to care for these populations, and

·          Research and publication to help study, improve and transform the care they receive

Our Services:

The Center for Key Populations, established in 2016, is the first program of its kind, recognizing the unique and
interrelated needs of five key groups who carry the highest burden of and risk for HIV infection and who belong to
communities that have suffered many barriers to healthcare: Men who have sex with men (MSM), transgender people,
people who inject drugs, people in prison, and sex workers.

The Center brings together, under one roof, healthcare and advocacy to the following communities: the LGBTQ (Lesbian,
Gay, Bisexual, Transgender, and Questioning) population, people who use drugs, the homeless and those experiencing
housing instability, the recently incarcerated, and sex workers. The Center offers numerous services designed to
address co-morbidities disproportionately affecting these populations including:

• HIV prevention, screening, and treatment

• Hepatitis C prevention, screening, and treatment

• Sexually transmitted disease prevention, screening, and treatment

• Substance use disorder management

• LGB-focused primary care

• Transgender health

• Primary care for the homeless

Marwan Haddad, MD, MPH

Marwan Haddad, MD, MPH, AAHIVS

Marwan Haddad is currently the Medical Director of the Center for Key Populations at Community Health Center, Inc. (CHC), the first center of its kind focused on engaging populations who traditionally experience barriers to comprehensive and respectful care. The Center recognizes five key groups who carry the highest burden of and risk for HIV infection and brings together under one roof healthcare and advocacy for the LGBTQ (Lesbian, Gay, Bisexual, Transgender, and Questioning) community, people who use drugs, the homeless and those experiencing housing instability, the recently incarcerated, and sex workers. Dr. Haddad joined CHC, the largest federally qualified health center in New England, in July 2006.

He received his Bachelor of Arts degree from Harvard College and his medical degree from McGill University. He completed his family medicine residency at University of Toronto and obtained his Masters in Public Health from Johns Hopkins University. He is board certified in Family Medicine. He is certified by the American Academy of HIV Medicine as an HIV specialist. He was also the recipient of the 2011 Primary Care Leadership Award presented by the Connecticut Center for Primary Care. Dr. Haddad is an Assistant Clinical Professor of Family Medicine at Quinnipiac University.

Since January 2012, Dr. Haddad has led the CHC Project ECHO HIV, Hepatitis C, and Buprenorphine programs which expand the integration of these programs not only within CHC but nationwide. This model of care utilizes didactic and case-based learning via weekly video conferences with medical providers, offering ongoing support, consultation and guidance to aid in delivering care to the HIV, Hepatitis C, and opioid dependent populations. Moreover, Dr. Haddad has taught and lectured at state and national conferences on HIV, HCV, buprenorphine and integrated care. He has published research on the integration of buprenorphine in community health centers examining both substance abuse as well as primary care outcomes.

 Ms. Harding-Wheeler was responsible for the development and implementation of new HIV prevention programs and the initiation of CHC’s PrEP (Pre-exposure Prophylaxis) Program to provide comprehensive healthcare services for vulnerable populations that experience disparities in health coverage. 

Additionally, Ms. Harding-Wheeler provides daily oversight to the Center for Key Populations, a drop-in center located in Middletown, which provides medical case management and other support services to individuals living with HIV/AIDS. 

In 2013, Ms. Harding-Wheeler became part of CHC’s clinical quality team after training at the Dartmouth Institute for Health Policy and Clinical Practice. She has since been the coach for several clinical microsystem teams, using quality management skills to assist teams in developing and implementing core quality improvement projects.
