Antiquity Staff

Staff listed here are full-time permanent staff. We also employ 3-5 as-needed staff regularly, and will hire larger teams for big projects. Antiquity was founded on the principle that cultural resource management staff should be treated with respect and receive adequate compensation and dependable schedules. Unlike other firms, we prioritize internships and seasonal terms for employees in support of their professional development and out of respect for their needs as emerging professionals. We typically hire several interns a year. Our temporary staff bring a wide variety of skills to the team.
