View all surgeonsReal experiences from patients who've trusted us with their care.
My primary care physician recommended Dr. Barnajian and his office staff were absolutely superb. The scheduling, the way they greet you when you walk in, it was as good a personalized service as I've had visiting a doctor... ever. Natasha in particular at the front desk was friendly, helpful... awesome.
Doctor Nasseri is wonderful, always answers our questions and always makes us leave the feeling good about everything!
Being diagnosed with cancer was really scary. Having Dr. Arena as my surgeon was amazing. Aside from being an excellent surgeon she is compassionate, caring, and takes time to listen to all of my concerns, every visit. I feel well taken care of, and tell everyone about her.
Surgery Group's expertise and compassion made a difficult situation so much easier. The minimally invasive approach meant I recovered much faster than expected.
