Director of Human and Canine Resources
Piper is a versatile member of the LGA staff. A young and energetic worker, she originally specialized in redecorating and light housekeeping, but quickly demonstrated her talent for managing human and canine staff members. She currently works from home but plans to incorporate site visits into her schedule in the near future. She has an interest in security and will likely involve herself in protecting the staff and surroundings. She feels that a work station near Dairy Queen should allow her to adequately monitor the activities around the office.

Macallan joined the LGA staff in late April 2017 and is still a security officer in training so she doesn't provide on-site services as of yet. She has a serious interest in security and property management, enthusiastically expressing her philosophy to mail carriers and other delivery personnel. In her spare time, she enjoys bird watching, cat herding and tossing squeak toys. She's shy at first, but she's likely to treat familiar visitors to an impromptu tap dance or merengue.
