Each has close to 20 years of experience in boundary resolution, topographic mapping, and all other aspects of the surveying industry. they gained their experience via first hand observation of and tutoring by their father who was also a surveyor licensed in Washington State.

Both David and Gary have a wide range of projects behind them varying from boundary determinations, residential subdivisions, aquatic leases, bathymetric surveys, GPS , to 3-D high definition laser scanning and flood mapping. Their backgrounds and experiences have given them excellent time management skills.

Throughout their careers they have forged lasting relationships with their clients. From these connections they draw the ability to rapidly establish as exceptional working relationship with both the professional community and government agencies.
