While overwhelmingly positive, a small number of reviews identify areas for improvement. A few patients describe Dr. Hollowell as occasionally brusque, unfriendly, or appearing rushed, with some feeling spoken down to or not adequately listened to during their visits. Two patients reported particularly negative experiences where they felt dismissed or scolded, leading them to consider changing providers. One review mentioned concerns about proper PPE protocols by nursing staff regarding glove use and hand hygiene. A handful of patients noted that while Dr. Hollowell is excellent, he can sometimes move very quickly through appointments or speak rapidly, requiring patients to ask for clarification or repetition.
