Every trip starts with one question: what time do you need to be checked in? From there we subtract the drive, the parking, the walk from the kerb and a realistic buffer for Northern Virginia traffic. The result is a pickup time that is genuinely calculated rather than guessed.
This matters most for appointments that are hard to reschedule. Specialists booked three months out, pre-operative clearances that gate a surgery date, and treatment courses where missing a session sets the whole plan back.
The return trip is treated as part of the same booking. Riders are not left to arrange a way home while still holding discharge instructions in one hand.
