David Haldeman
David Haldeman, Chief Executive Officer

David Haldeman is the son of Trella H. Romine, who in 1953 built the home that is now the Terradise Nature Center.

David was born in Marion, Ohio in 1945 and attended Mark Street School before moving to Caledonia in 1953. Attending Caledonia School through the 9th grade, he transferred to Marion Harding High School, graduating in 1963.  He obtained his B.S. in Education (Music Major) from The Ohio State University in 1967 after having played in the Jazz Workshop under Ladd McIntosh and the Ohio State University Marching Band. He taught at Pleasant High School and Mt. Gilead Elementary School before his marriage to Karen Meister in 1969 and subsequent move to Cincinnati in 1970. 

In Cincinnati, David taught music at Anderson Middle School, and then he and Karen purchased Vielhauer Pork Products at the historic Findlay Market in Cincinnati’s Over-the-Rhine district. An interest in science and technology prompted the purchase of a personal computer, which he soon learned to program.  This led to the founding of Terradise Computer Systems in 1983. He is currently president of that company.

David serves on the Board of Trustees of the Mt. Washington Cemetery Association as Vice President. He is a 60 year member of the American Federation of Musicians and continues to play the trombone in various professional groups in Cincinnati.

David and Karen have 4 adult children, one of whom is Terradise Nature Center Board Member and Treasurer, Jed Haldeman of Columbus.

After the death of his mother in 2013, David inherited the 6 acres on the right bank of the Olentangy River, which he donated to found the Terradise Nature Center in 2018.

Decker Southwest Geophysical Bio 20200205 (1)
David Decker, Executive Assistant

Dr. Decker has 25 years of experience working in different aspects of the radio frequency spectrum while both enlisted and as an officer in the U.S. Navy. During his time in the Navy he started out as a Fire Controlman – that is, controlling the firing of guns and missiles from surface ships. This job also entailed the operation, maintenance, and repair of gun fire control radars, missile fire control radars, 2D and 3D air search radars and their associated systems. During his first enlisted shore tour, then FC1(SW) Decker taught missile fire control system operations and tactics during the day while working on a BSc in Workforce Education and Development in the evenings and weekends.

As a Naval Flight Officer, Lieutenant Commander Decker flew in the S- 3B Viking and the EA-6B Prowler off the decks of the aircraft carriers USS Carl Vinson and the USS Nimitz. This job included the operation of several different types of radar and sensor systems, including weather radars, navigation radars, tracking radars, inverse synthetic aperture radars, forward-looking infrared detection systems, magnetic anomaly detectors and the Navy’s premier radar and communications jamming system. During his first shore tour as an officer he took the opportunity to get his MSc in the physics of sensor systems at the Naval Post Graduate School, with a concentration in radar and optical wave propagation theory.

Dr. Decker also has several years of experience in program management. As an Aerospace Engineering Duty Officer with the US Navy, he led a team of over 50 military and civilian employees in the very detailed work of installing classified weapons systems on Naval aircraft. This entailed knowledge and skills in systems engineering, contracting officer responsibilities, science and technology management and risk management. He took classes in all these areas and achieved the highest levels of training available from the military school of acquisition, the Defense Acquisition University, then put this knowledge to work for Naval Air Systems Command.

After retiring from the Navy in 2010, he returned to graduate school for a PhD in geology. Geology and caving had been hobbies since he was a small boy and in retirement, he decided to pursue that interest. While finishing his PhD, he decided to put all his knowledge, experience, and expertise into starting his own business and Southwest Geophysical Consulting was born. He is currently the Chief Executive Officer and Principal Geophysicist of this small but growing company that uses geophysics to locate caves and other karst-related features. Dr. Decker has recently served as a director on the Board of Governors for the National Speleological Society and is currently serving a term as a director with the Karst Waters Institute. He is happily married to the former Johanna Clinger of San Diego, California and will be celebrating his 25th wedding anniversary in 2020.

Emily Knapp

Emily Knapp is one of the Conservation Education Coordinators at The Wilds. In her current role, she manages a residential summer camp (WildeCamp), a teen volunteer program, and an adult volunteer program, while assisting with school visits and activities in the Kids’ Discovery Field Station. Emily’s goal is to educate visitors and campers on conservation efforts; to inspire and empower them to take action toward helping the planet, all the while encouraging and assuring them that their hard work is truly making a difference.

Emily graduated from Michigan State University in 2015, with a B.S in Zoology and a minor in Educational Studies. While she initially entered the field to assist endangered species, she’ll be the first to state that over time she’s developed an even stronger passion for the people that she interacts with. The brilliant minds that she gets work alongside each and every day, and the guests who walk away from The Wilds’ gates with a newfound appreciation for wildlife and a drive to do everything they can to help save it, is what motivates her to push forward toward conservation for all species, big and small.
