Dr. Krishnan was absolutely one of the kindest and most empathetic doctors I’ve ever worked with. He listened to my concerns and he helped control my pain, which was pretty bad at the beginning coming out of surgery as well as theShow more week after until my follow up when we got the Robo Tronics up and running, and I will say that both Kevin from Robo Tronics and Dr. Krishnan make a great team! I would highly recommend him to anyone that is experienced the pain I have had over the last 20 years. And ironically, I met one of the nurses who also had the Robo Tronics installed in her neck and I asked her if she mind telling me what it was for and she told me it was for mental health and I was absolutely amazed to hear that it treats mental health issues, such as anxiety and depression, etc. so once again I would give him 10 stars if I could as well as his PA Leslie, she’s so warm and easy to talk to and explained everything to me at the beginning as well as at my follow up visit everyone on the staff, including Daisy, At The Front Desk we’re just amazing! sincerely, Stephanie Oliva
