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.  

Valerie M Russell, ARNP-C


Valerie Russell joined the WUC staff in October of 2010 as our much needed Nurse Practitioner.  She is a native of Rochester, New York but moved to Indiana where she graduated from the University of Southern Indiana.  She is a board certified Nurse Practitioner in Family Medicine.  


Prior to joining WUC, Valerie previously worked at Cardiac Disease Specialists in Georgia and Central Florida Cardiology in Florida and brings with her over 5 years of cardiac experience.  


She also worked at South Lake Hospital and Southern Medical Group in Orlando, Florida prior to moving to Tallahassee.


Valerie is married and currently lives in Crawfordville with her husband and 2 daughters.

Emmanual "Tiffany" Northington, APRN

Tiffany, our newest Nurse Practitioner, joined our staff in October of 2019. She graduated from the University of Alabama at  Birmingham in Birmingham, Alabama. She is a Board Certified Family Nurse Practitioner. She is passionate about treating the whole person , not just the disease and seeks to understand the root cause of an illness or disease process. 


Tiffany previously worked with Children's Medical Services as a registered Nurse Care Coordinator treating children with chronic, serious or behavioral problems.  She also worked as an RN & Public Health Nurse Coordinator at World Transformational Ministries in Cameroon, Africa. There she provided prenatal care, assisted midwife with deliveries, coordinated vaccination clinics and provided public health education screenings for diabetes, hypertension, HIV/AIDS and nutrition.


We are thrilled to have her on board along with her 10+ years of experience in the medical field.
