How likely are you to recommend Dr. Johnston?

(Select your rating)
Dr. Johnston is the most responsive and attentive doctor I have ever encountered (I'm nearly 70). He responds to most messages I send him within an hour or less. He doesn't require extraneous tests and focuses on the immediate problem with an eye to a rapid resolution. I wholeheartedly recommend him, particularly if you are, or what to be, part of the Baylor Scott & White system.
