If you're open to co-oping, check out FB Meekins preschool in Vienna. We moved here when my son turned 2 and he entered their 2s class. It was a great way for him to start preschool and for me to meet people. It's not faith based and is more than 50 years old. It's a great community and we stay in touch with many friends we met there 5 years ago! Welcome to the neighborhood!
