We saw Dr. Marcus for a 2.5 month old baby with a submucosal posterior tongue tie that had been missed by an ENT and a 5 yo with a classic tongue tie that seemed to be causing some speech issues. It started out with a long phone consultation before we scheduled the appointment. Once we got there, Dr. Marcus was great, very personable, explained things well, and wonderful with my 5 yo. My 5 yo left his office with clearer speech, and my baby can now move his tongue all over the place. Dr. Marcus called that night to check on them, and then since we had to travel a ways to see him, he was great about reviewing followup pictures via email to see how they were healing. I would highly recommend Dr. Marcus for anyone with tongue/lip ties.
