David A. Keen, MD, MPH

Dr. David Keen left his homeland of Jamaica to attend Howard University in Washington, DC graduating with an MD in 1985.  He did his residency in Florida at Tallahassee Memorial Regional Medical Center’s Family Practice residency program.  


After graduating in 1988 and becoming Board Certified, he joined Leon County’s Lincoln Neighborhood Health Clinic in French Town.  Two years later, he became the Medical Director of the Wakulla County Health Department and held this position for 11 years.  While serving as the Director of the Health Department, he realized that there was a void in the health care delivery and accessibility in the county as all after hours care and diagnostics services were referred out to Tallahassee.  With this in mind, he formed Wakulla Urgent Care & Diagnostic Center (WUC) filling a much needed gap in the community.

One of Dr. Keen’s greatest passions is to pursue medical missions.  Since leaving Wakulla Health Department in May 2003, he has done over 70+ mission trips to 5 different countries.  He is the Medical Director for his own organization named Caribbean American Medical Educational Organization (CAMEO) where he continues to do 5 medical mission trips each year.   


Dr. Keen currently lives in Tallahassee and is married and has 2 wonderful children.  

Bianca Fleurant, ARNP

We welcome Bianca Fleurant, ARNP, as our newest member to join our staff. She received her Bachelor’s Degree in Nursing from Florida Agricultural & Mechanical University in May 2013 and then later into the Nurse Practitioner program graduating with Honors with her Master’s Degree from Chamberlain University in August 2022.  Bianca comes to us with several years of experience working as a Registered Nurse in both a hospital environment and a rehabilitation facility.  Her strong analytical, critical judgement and decision-making skills will make her a great addition to our team.

Bianca was born in Brooklyn, NY and was raised in Haiti until age 12. She currently resides in Tallahassee with her husband and three children. In her spare time, she loves cooking, African dancing, reading and enjoying quality time with her family.  It is her mission to travel back to Haiti to serve her community.
