We show that the type III seesaw mechanism opens up a promising possibility of searching the Higgs boson in the b-bbar channel through the Higgs production associated with a charged lepton coming from the decay of the triplet fermions. In particular we look for the 2b signals with trileptons and same-sign dileptons to construct the Higgs and the triplet fermion mass and calculate the reach with the integrated luminosity of 10 1/fb at the 14 TeV LHC.
