Our library of surveys which dates from the 1940's to the 1970's were executed by Edgar C.M. Burkhart.  The bulk of the more than eleven thousand surveys in our library were executed by or under the company's founder Edward A. Cleaver, from 1972 until his retirement in 2012.  With over eleven thousand surveys in our records, it is likely that if you are in Northeast, North Central, or Central Missouri we have done work near you.
