Fantastic! Knows what he’s talking about.
He is very nice & explains everything.
Very patient and kind
Excellent experience with Mark Landis, migraine specialist. Even through a virtual appointment, he was attentive, on time, and really listened to my concerns. I never feel rushed and he always makes sure my questions are answered. It’s rare to find a specialist who is both knowledgeable and genuinely caring. Highly recommend.
Mark is knowledgeable and listens to your symptoms to come up with a plan that works for your headaches/migraines he’s also good about giving samples to help figure out which medication will work so you don’t have to get a full prescription of something that may not work.
Been seeing Mark for many years..he has to clean out my ears..I have artifical ear drums.
Very competent
Mark is the best! He is excellent at providing Botox effectively and with very little pain. He is friendly and kind.
