There are three entrances to the office, one of which is wheelchair accessible (The entrance outlined in the picture to the left). This is the easiest entrance.
You can access the office from the other doors, but it is very difficult to navigate.
The easiest access point is using the left-hand door (wheelchair-accessible entrance). Once you enter that door, Thrive By Design is the first door on the right.
Should you have gone in the middle (Main) entrance, take the elevator down to the lower level. Exit the elevator and walk until you see a cargo elevator. Once you see that, turn left and head all the way down the hall. The office will be the last door on the left, across from the bathrooms.
