Kary Gregoire, Past-President

Hi, I’m Kary Gregoire.  I grew up on a farm east of Wakonda in southeast South Dakota.  I am married to my wife Becky and have 3 children; Alicia, who recently moved to Denver to start a job as an Auditor/Accountant, Nick, who is currently a Freshman at SDSU studying Engineering, and Mason, a Sophomore at Yankton High School.  We live in Yankton and have lived there for the past 20 years or so.

A little bit about my education/experience…following the completion of my Associate's Degree in Civil Engineering from Southeast Technical Institute in Sioux Falls in 1995 I took a position with Brandt Land Surveying in Yankton.  I then went on to work for the SD Department of Transportation also in Yankton.  Originally I started as an inspector/surveyor but after 6 years I became licensed in South Dakota and took the position of Mitchell Region Land Surveyor.  I held that position for 15 years until recently taking a job as a Land Surveyor for the Indian Health Service in Sioux City, Ia. My current position involves all aspects of surveying but our main focus is easements for new water and sewer projects in and around the Indian reservations served by the Sioux City District Office, which include reservations in 3 states.  In South Dakota, our office does work on the Rosebud, Yankton, Flandreau, and the Lake Traverse Reservation. In Nebraska, we work on the Santee, Winnebago, and the Omaha Reservations and in Iowa, we do work on an Indian settlement Northeast of Des Moines called the Sac and Fox.  I have been working for Indian Health Service since January of 2019 and it has been somewhat challenging to adapt to the Federal workplace but working on the Indian Reservations is very interesting to me as a Land Surveyor.

Paul Letsche, President Elect

My name is Paul Letsche, and I am a Sioux Falls native graduating from Washington High School in 1995. After working a few years in construction after high school I was looking for something more fulfilling and heard about land surveying through a friend who worked with a surveyor. After enrolling in the Civil Engineering Technology program at Southeast Technical Institute in 2002 I knew from day one that surveying was for me.  I graduated in 2004 with an Associate of Applied Sciences Degree in Civil Engineering Technology. Starting out working for the engineering firm Howard R. Green Company after graduation I then moved to a position with Midwest Land Surveying in 2006. In 2010 I started with East River Electric in Madison SD where I am currently employed as a Land survey Coordinator. I have been a registered Land Surveyor in South Dakota since 2015 and hold an FAA Part 107 Remote Pilot Certificate.

It is a privilege to have the opportunity to serve the SDSPLS membership as a board member and representative.
