A Strong Foundation - And A Second Generation

Hydro Consultants was founded in Baton Rouge, Louisiana in 1984 by a group of talented surveying and mapping professionals led by the company's President, Ernest Gammon.

A graduate of Mississippi State University, Mr. Gammon is a Professional Land Surveyor, licensed to practice in Louisiana and several surrounding states. He is also a Professional Hydrographic Surveyor who was granted Board - Certification in this highly specialized field by the National Society of Professional Surveyors (NSPS).

During his career, Mr. Gammon has been elected by his peers to serve numerous terms on the NSPS Board of Governors, the NSPS Standards of Practice Committee, the NSPS Education Committee, the NSPS Continuing Education Committee and the ACSM Board of Directors. He has also served a six-year term on the Louisiana Professional Engineering and Land Surveying (LAPELS) Licensing Board.

As the original management group began approaching retirement age, the company's second-generation leader, Ernest Gammon Jr., continued to assemble a management team that has expanded the company's capabilities while maintaining and enhancing our commitment to quality and safety. Ernie Jr. received his degree in Civil Engineering magna cum laude from Mississippi State University in 1994. He is licensed as a Professional Engineer in the state of Louisiana, and is licensed as a Professional Surveyor in Louisiana, Texas, Mississippi, Florida, Alabama, and Illinois.
