I suffer from Eosinophilic esophagitis, & Marius has been the most qualified surgeon that I have ever had doing the procedure of GI endoscopy. He is very informative. About the only person I would trust to do a Endoscopy procedure correctly & safely. I very much recommend, hence 5 stars.

Marius was the first person to take my condition seriously, and do everything in his power to help me. Even when my issues went outside of his scope of work. He is empathetic and diligent, and has been an heavy weight in my corner and my ace up my sleeve. I’m so grateful for him, and would highly recommend.
