Dr Casillas and his staff should be a 6 star! Dr. Casillas was amazing, explaining things thoroughly to my husband and I. Neat incisions, minimal pain. Staff were great, all nurses were wonderful, from registration to post op, I felt I was in good hands. I highly recommend Dr Casillas and Backus Hospital. Thank you!

5 out of 5 stars

Dr. Casillas is an excellent surgeon and an extremely nice guy. I had an ileocecectomy done (due to Crohn’s disease) earlier in the year, and I’ve had no complaints. I highly recommend him, his PA Megan McNamara, and his team.
