What Hemphill does

Hemphill, LLC is a privately held, family-owned telecommunications infrastructure company headquartered at 1305 N Louisville Ave, Tulsa, Oklahoma. Founded by Elmer L. Hemphill in 1957 as a drilling operation, the company pivoted into wireless infrastructure in the 1980s when its foundation-construction experience earned it the role of building foundations for US Cellular's first cell towers. Today the firm develops, owns, and leases tower sites for wireless networks, runs a Build-to-Suit program that delivers turnkey site development, and operates a portfolio of modular tower structures (MicroTower up to 40 feet, MiniTower 40–160 feet, and the Modular On-Grade Tower™ up to 160 feet) that can be deployed without excavation or guy wires. The firm is vertically integrated through 450,000 square feet of medium-to-heavy industrial manufacturing space in Tulsa equipped with overhead bridge cranes, supporting in-house steel and tower fabrication.

Revenue is generated through five streams: recurring tower-site leases with collocation to wireless carriers; Build-to-Suit professional services covering land acquisition through construction; hardware sales of solar products (FiberReady™ temporary-power system and Zeno™ portable solar hybrid generator) to wireless and industrial buyers; turnkey private wireless network and TSA compliance services for the oil and gas industry; and small-dollar industrial and office space leasing via the Hemphill Create manufacturing incubator ($200–$600/month). Go-to-market relies on direct enterprise sales, a structured collocation application process, and recurring participation in Competitive Carrier Association (CCA) events. The proprietary PolarisBPM project management software and standardized Tower Site Development Specifications underpin the operations.

The company is led by John Hemphill (President, with the firm since 1983), Scott Hemphill (Vice President & CTO, joined 2014), and Kristen Bennett (Vice President & COO), supported by Directors with 28–30+ years of telecommunications experience across US Cellular, AT&T, Nextel, Black & Veatch, Horvath Communications, and other operators. Operations are concentrated in Oklahoma and adjacent U.S. markets; no institutional, private equity, or venture capital backing is disclosed.

Others

• Cambium Networks: Cambium Networks provides wireless broadband equipment that integrates with tower infrastructure. It is a Hemphill partner but adjacent in the value chain — supplying radios and access points rather than towers themselves — and serves similar carrier and private network customers.
• Sol-Ark: Sol-Ark manufactures solar inverters and energy storage solutions that complement Hemphill's Zeno and FiberReady solar products. It is a Hemphill partner providing enabling power electronics rather than competing in tower leasing or site development.

Broad incumbents

• American Tower Corporation: American Tower is the world's largest tower REIT, owning and operating over 220,000 communications sites globally.
