Born and raised in The Woodlands, Texas, Dan was destined to be a Land Surveyor. As a 3rd generation surveyor, and beginning when he was old enough to carry a 5-gallon bucket filled with a steel tape, chaining pins, and a plumb bob, he would work every summer break throughout grade school with his father Robert (Texas R.P.L.S. #3968). After graduating from high school, Dan entered Texas A & M on a pole-vaulting scholarship while studying Civil Engineering. Three years later, he enrolled in the College of Technology (Land Surveying & Mapping program) at the University of Houston where he worked full-time with his father at Pinnell Survey, Inc., while attending class full-time in the evenings. Dan completed his college career in 1996 with a Bachelor of Science degree in Civil Technology (Land Surveying) and minor in AutoCAD. He immediately began intense studying for the state board exam and passed in the Fall of 1999. He went on to obtain registration in Oklahoma two years later. Now, co-owner and member of The Pinnell Group, with 40 years of Surveying experience, 23 years as a professional, Dan is determined to serve the public for years to come.
