Dr. Reshma Khan is the founder and Executive Director of Shifa Free clinic. She was born and raised in India and came to the United States in 1998 to visit her brother. Here she met her husband Dr. Ahsan Khan and both decided to get married and she immigrated to the US. After completing her medical residency in OB/GYN at Saint Elizabeth Hospital 2003 Ohio she worked in private practices in Indiana and Maryland before moving to Charleston SC in 2007. The move to Charleston SC was due to her husband’s job offer at the Veterans hospital. In the meantime, they had 3 children.

Moving to Charleston in 2007 she started her job at the Ralph Johnson Veteran’s hospital. The patient population was very different from the previous jobs and she found herself drawn towards them and felt her presence was making a difference in the lives of the people she served. Simultaneously she was also learning more about her faith in an attempt to raise children with values that were prescribed in her holy book. This combination of knowledge gained from faith and working at VA made her strive for more giving. She started to feel more accountable for the blessings given to her and wanted to share it with less privileged. Initially, she wanted to just volunteer her time as a physician but it was not working out as she had desired. She wanted to give more than what she was able to at that time.

The passion to serve and a burning desire to have medical services for under served and uninsured at the same level as those who have insurance she dedicated all of her efforts on a volunteer basis to research, start up and develop a clinic where her patients would get the same care as she was providing at her job. With the blessings of Almighty, she was able to start a free clinic in 2012 which initially started as a 4-hour clinic on Saturdays. She continued to strive and look for avenues, collaborated with local organizations, reached out to the community to continue to take clinic a step further each time one of the steps were accomplished. This was all on a volunteer basis done all along with her regular job and raising responsible children

Recently in 10/2015, Dr. Khan took a major decision supported by her husband. After serving in VA for 8 years she decided to pursue her volunteer work on a full-time basis to serve humanity and dedicate all her efforts to take the clinic to the next level. She has a vision for future where she would like to see this clinic serving as a portal for good not just in terms of service but also bringing people of different faiths, races, and religions on a common platform of deeper human connection, understanding, peace, and love. Shifa Free clinic currently is full time operating Monday through Friday 8.30-4.30 pm serving multispeciality needs of primary care, advanced GYN, vision care, Vaccine, mental health and Pediatric services and an onsite dispensary for free medications for the uninsured and indigent population regardless of race, religion, gender, or ethnicity.
