Very good and has a good bedside manner.
Was efficient in cleaning my ears and friendly.
He always listens to my concerns and the factors involved before making any medical changes. He is a great PA!
Mark Landis is truly amazing. I suffered from migraines following an auto accident and later learned they were vestibular migraines, something that can be incredibly difficult to live with and even harder to properly treat. From the very beginning, Mark Landis listened carefully, took my symptoms seriously, and never rushed the process. He adjusts my medication thoughtfully and in a timely manner, always based on how I’m actually doing, not a one-size-fits-all approach. His knowledge, responsiveness, and genuine care have made a significant difference in my quality of life. I couldn’t ask for a better practitioner and highly recommend him to anyone struggling with migraines, especially vestibular migraines.
He was great and so personal.
Great with patients!
Excellent bedside manner. Very patient and informative and I felt very comfortable with him and he cared. Did not feel rushed. Very happy with him and would see him again. Excellent
Quickly addressed the problem of was buildup.
Mark is always knowledgeable, patient and kind. He takes time to offer support and answer questions.
Mark is great! Friendly and super professional
