A Lifetime in the Making

The idea for Cell Tower Osprey Management, LLC (CTOM) was “hatched” by current Principal and owner Kathy Maechtle’s late husband, world-renowned raptor biologist Tom Maechtle.

Specializing in avian migration studies, the majority of Tom’s studies followed the sojourning Peregrine Falcon—from the arctic cliffs of Greenland to the southern coast of Chile. Along the way he cultivated relationships with esteemed scientists and fellow researchers, leaving his professional mark on the nascent avian satellite telemetry technology studies of the 90s.

Tom honed his research skills under the tutelage of respected avian scientists like Drs William G. Mattox, William S. Seegar, and Mark Fuller, becoming a leading raptor research biologist and building a personal board of trustees who shared their knowledge and wide-ranging resources.

When Tom met Clifford W. “Bud” Anderson, Bud had recently invented the Osprey Nest Excluder (ONE), a device specifically for preventing ospreys from nesting on cell towers. Bud sought Tom’s assistance to market the ONE, and together they discovered a void in the telecommunication industry’s knowledge regarding the biology of nesting birds and the regulations and agencies that protect them.

Tom successfully developed and marketed a plan to bridge the knowledge gap for T-Mobile, securing a service agreement shortly before his untimely death due to pancreatic cancer in December of 2016.

After a brief re-calibration, Kathy and Bud moved forward to fulfill the product and service commitments made by Tom. It is in his honor that CTOM (“See Tom”) thrives.
