I want to thank the Casa Colina staff and Dr. Kenneth Lee for the excellent experience I had on May 2nd 2025. I went in for a colonoscopy and an endoscopy all the staff was super sweet and professional. They took excellent care of me from the moment I went in. I would definitely recommend Casa Colina.

I've been taking my mom for dialysis to Casa Colina since November 2024. They've been great with my mom. Blanca and Heidi in the front office are amazing! So helpful, kind and professional. The nurses have treated my mom with understanding of what she has to go through. My mom is 86. I drop her off knowing she's in great hands.
