Dr Marius is a great doctor. He goes over and above the expected standard of care when dealing with his patients. He’s smart, kind and patient, especially during stressful times. He genuinely cares about people, and that coupled with the practice of medicine makes for an excellent medical practitioner.

I have been consulted by Marius for the last 6 months. My experience with Marius has been really positive - I have found that he has multiple options of treatment available and communicates these clearly. Consultation responses, prescriptions and general concerns have all been addressed and answered really quickly which is much appreciated and alleviates a lot of the stress! Would highly recommend to anyone looking for a great Gastroenterologist.
