I was very anxious about needing a colonoscopy due to a condition I have that can cause low sodium. He listened to my concerns and consulted with a nephrologist during my appointment. It was a huge relief for me.

This office will get you in and treat you well. It is refreshing in these times. Felt like every one from the scheduler to the check out lady was glad I was there and would take care of my needs. I can't say enough about Dr. Altawil (Johnny). He took time with me, asked questions and really listened to me. He is a highly credentialed and experienced physician who has prioritized valuing his patients. Felt like I was in great hands. Highly recommend

Dr. Altawil is very professional, but feels like an ole pal from long ago. He’s game on and always helpful and is very knowledgeable in his field. Makes a person feel like he actually cares about you as a patient, and for me, it speaks volumes of his character. And this character is exactly aligned with how I imagine he’d be if you saw him at the mall. Great doctor! Great guy! Sincerely, Jason Gartin…
