May 16, 2025Great visit.
May 14, 2025Dr. Ling spent lots of time explaining my options and giving me time to provide my input. He spoke in patient-friendly language, while also considering my level of knowledge in healthcare. He presented research backed options while considering my subjective responses.
Apr 30, 2025My experience with Dr Ling could be compared to visiting a family doctor of years gone by. He was so personable.
