    • “Finally, I am taking a moment to reach out to you with heartfelt thanks for giving me "a perfect knee." From the moment we met, I was inspired by our engaging and compassionate manner. I felt at once respected and valued as your patient. As a retired RN, I believe that managed care's age makes it almost impossible for healthcare professionals to practice with these qualities. You will be happy to know that I am overjoyed with the outcomes of the knee replacement. I am so grateful for the returning strength and confidence that allow me to enjoy hiking, cycling, horseback riding, and weight training. Every day I am amazed. Let me encourage you to keep your heart and vision in your practice. You can make a difference in people's lives. Clearly, your practice exemplifies excellence, but what remains uniquely wonderful to me is your ability to express kindness on every level, in every part of my experience with you. Stay well, Dr. Nishiyama. You are a blessing. You truly are incomparable. Warm regards.”
