I have been searching for a new Gastroenterologist for a few weeks when a friend of mind…read morerecommended Dr. Khan. I called Dr. Khan's office and was told that he was really booked. I took an appointment and waited my turn. The wait was well worth it. On my first appointment we went over my health history and my gastroenterology-related issues. Dr. Khan gave me an order to have an upper endoscopy performed which was completed on 12/09/2021. I am very happy with Dr. Khan and his bedside manner. I feel very fortunate to have become one of his patients.

I've been a patient for YEARS and only managed to see Dr. Lafsky in office ONCE due to repeated scheduling errors on their end. The final straw was after being denied a scheduled appt. With Dr. Lafsky by Nancy the office manager. All bc I missed an appointment while I was in the hospital with SEPSIS. Instead of telling the doctor I was there she sat me and my MOTHER down for 45min to lecture us about missing appointments. I even called from my potential deathbed to cancel and i saw Dr. Lafsky while in hospital!! Later that weekend, I retroactively received an invite from the receptionist Sam to an entirely different appointment the previous month that I did not make nor was I ever informed of. Clearly trying to clean up a screw up. So, after trying to schedule an over due Endo and colonoscopy for 3 years with this office, I finally gave up and found a new GI. I came in as a new patient, had my first appointment, and both procedures scheduled and performed in less than 2 weeks. If you are having issues with this office, it's them not you, just run. P.s. shout-out to Reston Gastro Health! It's a 2hr round-trip, but probably just gained me years of life back.

He is one of the few doctors that will follow up with a phone call after lab tests, something that most doctors no longer do. The reception area is clean, the staff is pleasant and organized.
