  • "He diagnosed and repaired my double hernia. Was the man, no issues whatsoever. Good sense of humor, and very personable. If anyone is having hernia surgery, I would recommend Newton Wellesley, and definitely Dr. vonRyll Gryska."

  • "Highly Recommend - Both my husband and myself have gone to him for surgical procedures and think he is great. He is very intelligent, an excellent diagnostician and has a great bedside manner and sense of humor."
  • New Year’s Day Letter, 2010
  • "Dr. Gryska, the holidays are a time to reflect on what we’re thankful for, and I’m so grateful you were on call the night you operated on me, and I thank you for your care and confidence in me during my recovery. It was the most challenging time of my life and I couldn’t have done it without you as my surgeon. Now, three and a half years later, my life is so much better, I was married two years ago and we are expecting a baby in May. I wish you and your family a very happy holiday and healthy new year ahead!"
  • Letter to the President of Newton Wellesley Hospital, 2005:
  • "...It turned out that my sister did need surgery. I can’t say enough wonderful things about Dr. Gryska. He understood the unique situation we were all in. He took the time to literally draw and clearly explain the procedure he was recommending. He made sure that not only I understood, but that my sister and our mother (who speaks very little English) also understood. He exuded confidence in his treatment plan. I have to say that I can speak to his personality but I had little to assess his surgical skill. However, given that my sister has had a quick, uncomplicated recovery leads me to believe that he is indeed talented. He is a rare surgeon that has the ability to speak to patients in laymen’s terms, and is truly gifted as a surgeon."
  • "Dear Dr. Gryska, At this very moment my husband is in your hands. It is amazing I feel absolutely content, I have no fear. I know he is in great hands, and in a great heart. Regardless of what happens today I’m very grateful to you for your care, concern and honesty. You have been like a spring breeze. I know you will try the best for my husband, therefore, I’m content. I know I’d be happier to meet you under other circumstances, however I’m happy about you taking care of one of my treasures. Thank you for everything." (Note: the patient did very well and made a full recovery.)
  • "Dear Dr. Gryska, As you have no doubt discerned, I tend to be anxious in new situations. When my health is involved, the anxiety is exponentially increased. Your kindness, patience and understanding (not to mention skill) have been a source of great comfort to me. My trust in you has made this experience much easier. Thank you for everything."
  • "Dear Dr. Gryska, You gave me back my life! Please take good care of those precious hands! I pray that God will take good care of you and hope everyone appreciates you as much as I do! Please hang this in the waiting office so everyone can read it! That’s how grateful I am!"
