1 /5 Candace Krull: After being referred to Dr. Oh by the ER, it took over a month to get an appointment, followed by weeks of waiting for diagnostics and then weeks for treatment. His office is difficult to reach, with poor communication and no follow-up after procedures. I was also scheduled at a different office without being informed, only discovering the change when I called to confirm my own appointment. Dr. Oh is nice, but the long wait times and lack of communication have been incredibly frustrating.
