We present a short description of a quantum Monte Carlo technique that has proved useful for simulating many-body effects in systems of interacting fermions at finite temperatures. We then report our preliminary results using this technique on a single impurity Anderson model. Examples of such many-body effects as local moment formation, Kondo behavior, and mixed valence phenomena found in the simulations are shown.
