If saints wore lab coats and surgical caps, Dr. Benet would be whom you would see.  My mother had a bad fall a couple of months ago, and Dr. Benet called me and laid it on the line and cut to the chase - operate now, or she will perish.  Fast forward a few months and some follow-up surgery, Dr. Benet was once again on it, and the best of the best.  Dr. Benet has been my mother's greatest advocate and works selflessly, putting the interests of his patients above all else.  Had he not been on call the night of her accident, it is simple - my mother would be dead.  Finally, I consider Dr. Benet to be a friend.  He is doing what he was put on this Earth to do, and is simply the best of the best.

I wanted to take a moment to express my deepest gratitude for the exceptional care you provided to my mom. Thanks to Dr. Benet's expertise and dedication, she has not only made it through her surgery but is also recovering wonderfully. Your skill and compassion truly saved her life, and we will forever be grateful. It’s rare to find a doctor who combines such remarkable professionalism with genuine kindness, and we feel incredibly fortunate to have had Dr. Benet as her surgeon. The surgery went so smoothly, and my mom is feeling better than ever. We couldn’t have asked for a better outcome. Thank you once again for everything you did for her.

I can't recommend Dr. Benet enough! After a stressful ER visit, I reached out to his office and his staff (Herlyn) was incredibly friendly and super helpful. After a scary diagnosis, I was nervous but Dr. Benet immediately put me at ease. He made me feel truly heard and asked thoughtful questions and took the time to address all my concerns. This was without a doubt the best experience I've ever had with a doctor. On top of his compassionate approach, Dr. Benet is very knowledgeable and clearly an expert in his field. I’m so grateful for his care and expertise

Dr. Benet is an incredible neurosurgeon who truly cares about his patients. His expertise, kindness, and dedication made me feel completely safe and confident.
— Annika S.
Dr. Benet and his team went above and beyond anything I have ever personally witnessed in the medical field and all that entails with emergency surgery. His team went all hands-on-deck to help coordinate MRI's and the necessary insurance, blood work and referrals to save my partner from a potential life-threatening situation. This is in addition to an absolute perfect surgical outcome. I can't thank Dr. Benet and his team (Herlyn was an absolute Angel) enough...in fact words won't do it. If surgery is in anyone's future...no one else would I ever recommend other than Dr. Benet. ~Tracey and Luke H.
