"Have been a patient of Dr. Schwartz for many years. He has always given me the best of care. Listens to me and offers the best resolution. Never has the "I'm the doctor and you're only the patient" attitude. I would recommend him highly."
"Barbara MacCollum is a great gastrointestinal Dr. She was recommended by one of her patients who happens to be a friend of my husband and I. She made time in her busy schedule to see my husband when one of his tests came back questionable. She was patient, informative and kind, made us feel completely at ease. As a last thought, we are grateful for Dr’s like her who are compassionate and caring. John and Tena Roberge"

"Dr Schwartz is a great gastrointestinal doctor. He explains everything that you're going to go through in great detail and it makes you feel completely at ease. When when you're colonoscopy is all over he gives you a great understanding of what to expect and what he found. I've used Dr Schwartz for My colonoscopy and endoscopy for at least 20 years and wouldn't go to any other gastrointestinal doctor."
"I am so glad i got a referral for Dr Schwartz. He explained to me what potentially happened to me. He spent lot of time explaining me things and making sure i understand everything going in my body.

And even if something happens to me again, I know Dr Schwartz will make it right. Thank you very much Dr. Schwartz."

"Dr Schwartz is terrific. He listens attentively which is refreshing these days. He addressed all concerns. And he is kind. I felt so at ease and comfortable. His front office is equally professional and friendly. So that is a home run. So glad I found this practice."
"This is the best doctor I have experienced in my life."
"Dr. Schwartz and his staff were all professional and knowledgeable. His bedside manner was old school. He paid close attention to my needs and took ample time with me all 3 visits. He made me feel like I was in good hands despite me being late my first visit because I’m new to the area and went to the old office. Even my first appointment he took his time with me. Maybe I’m just jaded from the cattle call approach from doctors in California but so far every doctor I’ve seen in Arizona have all had this old fashioned bedside manner. Thank you Dr. Schwartz for your services and your friendly staff."
"Always amazing care and customer service."

As a former practicing physician, I know what good health care delivery looks and feels like!"
