Nan Carlson is our Director of Land Administration, coming to us from Associated Resources, Inc., where she's worked since she joined the team in 2004. She ended up in the industry by chance, seeing an open position at an independent office support company similar to ARI. However, her father was a landman so she may have been destined for the industry. She’s spent her career honing her skills in land and lease records, lease records operating systems, conversions, lease and title research, division order calculations, and record-keeping at various companies across the country. At one point, she was in charge of converting a past employer’s 20,000+ lease records to an in-house system, so she’s no stranger to large projects.
