This is one I've been excited about for a little while now. Check it out and keep it on watch. RVDO Ms. Ellis began learning various aspects of the oil business from her father's oilfield business activities while growing up in Midland, Texas and through her own direct experiences with major oil and gas companies, working with Shell Oil and Pan American Production Company (now BP), respectively in Midland and Houston, Texas. After moving to Austin, she became a licensed real estate agent in 1985 and was an active and successful Realtor for many years. In 1997, she met Mr. Herzfeld after he moved Property Development Group, Inc. (PDG) to Austin. She joined PDG as the general office manager and has been instrumental in setting up all new accounting software and investor contact files. Her duties have evolved over the years to also include oil and gas accounting, distribution of operating statements, revenue checks, joint interest billings, accounts payable and receivables, plus communications with working interest owners and field vendors for each project.
