I am Dr. Theodore Osuala, a seasoned psychiatrist who set out initially working in family medicine, treating people with different ailments. Over the years I found out that a particular group of patients needed more attention and care, so I went into psychiatry and I have been in it and loving it since 1996.

I started my career in psychiatry training at University of Texas, Houston and completed it at University of Maryland Baltimore. I took a fellowship training in Geriatric psychiatry with special emphasis in Dementias and other psychosomatic illness in our elderly population.
