Can't offer an opinion of the Dr., I was never able to get through the appointment phone line. No one answers it. Funny though, called my referring DR. and they got straight through. Only catch, it was on the provider line, not the patients line. Obviously if you are a DR., you can get straight through, a patients not so lucky. Called Monarch Healthcare for help, they got straight through, but again on the providers line. I ask them to try the Patients line and at 11:50 they were at lunch.

Dr. Wallace, I appreciated your upfront honesty from the moment of our first appointment and I even told my father, "I like this guy!" Thank you for keeping your word to me and getting back to me by phone (with my test results) without setting up a wasted appointment. Deeply appreciate this as my life is busy enough!

Dr Wallace was a breathe of fresh air. A Doctor who was easy to connect with, knew his stuff, and I was perfectly comfortable after my first visit. The surgery went exactly as described and the timelines for recovery were right on. Thanks Dr. Wallace

30 September 2016 I would like to commend Dr. William Wallace for the robotically assisted surgery he performed on me at Saddleback Memorial Hospital in Laguna Hills, CA, ten days ago. It was for problems I was having with Gerd and a Hiatal Hernia (Nissen Fundoplication). Pain was minimal and the recovery is progressing beautifully. (He also has the best bedside manner I have ever seen in a doctor). Lois Hansen Laguna Niguel, CA

Dr. Wallace and his staff are fantastic. He is very open with his patients as to what your options are. Nurses and Doctor assistants are super and the staff behind the desks are super nice along with everyone in the office. Shout out to Letty and Christina.

I'm currently 6 weeks post op from hernia surgery, and overall my experience was very positive. Dr. Wallace was amazing! He was very thorough, attentive and patiently listened and addressed each of my concerns. The surgery went great, and both nurses and doctors called and followed up with questions I had regarding my post op. Going under the knife is no small feat and being in the hands of someone you trust and respect is crucial. I can't thank Dr. Wallace enough!
in Long Beach, CA |
I would definitely recommend Dr. Wallace based on the experience I have had not only with the surgery itself but also the time taken before my procedures and care given during my recovery. My procedures involved multiple doctors and Dr. Wallace was there every step of the way. He ensured I understood everything that was happening and most importantly, ensured I had the proper care after the procedures in addition to his own follow up. He is a truly caring doctor and I highly recommend him.
