he's quite simply a nice guy with a big heart

Dr. Li clearly loves his work. When you meet or talk with him he listens carefully, is clearly engaged, and uses the most up-to-date equipment and techniques to evaluate your situation. When I needed very quick advice and a reference, he was incredibly responsive at a time when I needed it a great deal. I trust him completely. And, to make it even better, he's quite simply a nice guy with a big heart. I couldn't recommend him more highly.
