They opened Covenant Heating and Cooling with the idea that an HVAC business could succeed without sacrificing integrity or its commitment to serving others. Eleven years later, Jonathan now serves as president of Covenant. He is a State of Tennessee licensed mechanical contractor and a NATE certified technician. Jonathan is also the author of The Sole Proprietor's Handbook, hosts the Sole Success podcast, and is the head curator of Sole Success.
