Patients also share
A small number of reviews identify areas for improvement, primarily centered on communication pace and attentiveness. Two patients felt Dr. Kariuki was dismissive and interrupted them frequently, with one noting he seemed to be reading from a script rather than truly listening. Several patients mentioned he speaks quickly or softly, which created challenges for those who are hard of hearing or needed more time to process information. A few reviews indicated that he occasionally appeared rushed compared to previous visits, and one patient noted difficulty understanding everything due to the fast pace of conversation. One review also mentioned a preference for in-person visits over video appointments.
