We formulate the conformal bootstrap approach to four--fermion theory at its strong coupling fixed point in dimensions 2<d<4. We present a solution of the bootstrap equations in the five--vertex approximation. We show that the bootstrap approach gives a particularly simple way to obtain next to leading order corrections to critical exponents in the large N expansion and present the values of the anomalous dimensions of the fermion field ψ and the composite ψψ to order 1/N2.
