FAQ
Booking questions
Anything not covered, call 571-500-7030.
Do I have to book ahead?
No — walk-ins are welcome during open hours. Booking an appointment guarantees a specific time slot and a shorter wait, which is especially helpful on weekends and during peak hours.
What should I bring to my appointment?
A photo ID, any paperwork your employer / court / doctor has issued, and your payment method (cash, credit, debit, HSA or FSA). If you’re fasting, bring water — coffee with cream and morning meds break the fast.
Can I reschedule an appointment?
Yes, anytime. Call 571-500-7030 or reply to your confirmation email. There is no rescheduling fee.
Can’t find a time that works?
Call us — we’ll find one. Or walk in any time during open hours.
