Tower Rock is a private oil and gas mineral and royalty acquisition company headquartered in Austin, Texas. The addition of Dell’Osso, effective Aug. 18, rounds out the Tower Rock leadership team comprised of Torres and COO Tim Holland, who have a combined 28 years of experience in the oil and gas minerals and royalties space.

“Tower Rock has built a strong track record of growth and portfolio value creation for its investors despite extreme commodity price fluctuations,” Dell’Osso added in the release. “I am honored to join Oscar and the Tower Rock team as we write the next chapter of the company’s growth through a disciplined and technically-driven investment approach.”

Prior to Tower Rock, Dell’Osso most recently served for over two years as executive vice president and COO of Parsley Energy, a leading Permian Basin oil and gas E&P company, until the close of its merger with Pioneer Natural Resources Co. earlier this year. During his time at Parsley, he led company-wide development, production, engineering, geoscience and supply chain functions. 

Before joining Parsley, Dell'Osso was employed for over 13 years by Southwestern Energy Co., where he served as senior vice president and general manager of the Northeast Appalachia Division at the time of his departure. Other roles at Southwestern included management of exploration, production, midstream and commercial teams covering regions such as the Appalachian Basin, Midcontinent and the Rockies.

Dell’Osso earned a Bachelor of Science in Petroleum Engineering from the University of Texas at Austin and a Master of Business Administration from Rice University.
