*Dr. Ling has turned out to be a great replacement for *Dr. Erayet. I thought *Dr. Erayet was wonderful, but I am VERY happy with the care I have received from *Dr. Ling and will continue to see him.
Considering how young Dr Ling is...he speaks AMAZINGLY good 'old people"...He really made me comfortable about the upcoming surgery and medical care I will be needing and I know HE is the one I want to work with...His nurse is WONDERFUL and friendly...
Although I was disappointed when I first scheduled the appointment that I could not get in for three months, I was very pleased with Dr Ling and feel very comfortable that I am in his care.
I love Dr. Ling. He is thorough and explains procedures very well. He has an excellent chair side manner.
Dr. Ling is very good, he listen to what I have to say and explains himself very clearly to me. He tells me what medicines he is changing and why and what to expect from the change. He doesn't cut corners but does get right to the point.
