  • May 23, 2024

    Dr. seemed unsure about lab results; did not address issues of pain; offered no cause for pain; no meds prescribed or suggested.

  • May 1, 2024

    Dr. Choi researched everything. Received records, contacted pharmacist over confusion on prescriptions. Thorough in asking questions - examination & explaining where we were and where he suggested we go from here. Really appreciated the way he works.
