Prior to graduating NMSU in 1983, Berry formed and owned a construction/remodeling company in Dallas, TX which was sold in 1988. In 1989, Mr. Mullennix re-entered the oil and gas industry marketing oil and gas joint ventures for a Dallas based broker/dealer. In mid-1992 he formed Mullennix Consultants, Inc. which acted as an independent consultant and broker to investors and oil companies, consulting on financing (bank, institutional, and private) mergers, acquisitions and investments.
