We hired Jon to act as a consultant on an extensive and complex project, and he pretty much saved the day. His expertise was remarkable, even answering complex programming questions we had during an emergency, from his mobile phone while driving! He also was very candid about any limitations to what he could answer, and helped us route our inquiries to other specialists, a quality I really appreciate in a professional. I would recommend Jon and Calibrate Marketing without hesitation.
