Jay,
I like the home page in black, as is, you could make the links standout a bit more, also maybe linkify that PC image with your most important "who/what is MD Orlando" too.
The white text on black background on the sub-pages strains my old eyes, and I have a hard time focusing to read it. Maybe keep the black background, but add a background color to the text to make it easier on the eyes, or look for a different color against the black that doesn't produce as much eye-strain. (At least for my eyes, anyway. )
Overall, it looks professional and I like it a lot!
