"Excellent care by Dr Collins during a critical GI bleed. His professional timely attention and follow-up with explanations in lay terms gave us encouragement & confidence that we were in good hands. Following appointment with his staff, especially Shauna, nurse practitioner, showed care above and beyond ordinary. She took a personal empathic interest, even to the point of arranging a change of appointment with another specialist, so we did not need to handle that. Wonderful caring competent team; we feel fortunate."
