Patient Testimonials

What Our Patients Have To Say About Our Healthcare Services

“I have trouble putting into words just how fantastic Dr. Mehta is. He was there for me in my time of real need helping me through two major spine surgeries. He took the time to explain everything to me. Never pressured me to just jump into a surgery but rather provided me options. Once it became clear that surgical intervention was an absolute must he was very quick to respond, I was admitted to Hoag Hospital right away and handled himself amazingly. He is hands down the best surgeon I’ve ever met. I would highly recommend him for any spine surgery. I am so thankful to him for him. I had lost function to my arm and was very scared I would never be able to use my arm again however shortly after the surgery function to my arm is already coming back. Thank you so much for all of your help.”

J. Merrill

“I’m very thankful for the wonderful staff and physicians at Hoag. I was treated extremely well and everyone seemed genuinely concerned about my well being.”

Susie Chew

“My memory and naming ability are awesome now. My husband said from the moment I woke up from surgery, ‘The old Tiffany is back.’ Dr. Millett and Dr. Liu are phenomenal. I am so grateful for the help they’ve given me.”

Tiffany Mueller

“Dr. Park is a listener and a teacher. He carefully listened to all my issued, I know this because he went over everything I said one by one and helped me understand what’s happening to me. He made me also feel very comfortable and not be rushed. Most doctors’ office is very systematic and quick to dismiss you. Highly recommend him!”

Patient from RateMDs.com

“When we moved to Arizona, Dr. Millet asked me if I wanted him to help me find a doctor there. I said, ‘No. I’m staying with you. We’re with you for life.’”

Emily Shafer

“By monitoring me almost every day, being flexible and responsive, Dr. Mehta gave me the confidence that doing the procedure was the right thing to do.”
