Multiple regression with repeated measures (?)

I’d appreciate some opinions on how to analyze some data for a research project.  Each case in the analysis is a psychotherapist.  The dependent variable is a continuous measure of a certain client behavior, and we want to create a regression equation to predict the DV from three therapist characteristics while controlling for certain client characteristics (sex, age, etc.).  This seems to be a basic multiple regression situation, except that for each therapist there are three clients, and thus three DV values and three sets of client variables.

One simple approach would be to analyze only one (randomly selected) client from each therapist.  This would let us use the remaining clients as a hold-out sample for cross-validation.  But I wonder if there is a way to incorporate all the data into a single analysis.  

I’ll appreciate any thoughts on this!
