Patients appreciate
Dr. Marc Shalek receives overwhelmingly positive feedback from patients who consistently praise his exceptional bedside manner, professionalism, and clinical expertise. Patients repeatedly describe him as caring, compassionate, personable, and genuinely interested in their wellbeing, with many noting he treats them like family or friends rather than just patients. His communication skills are highly valued, with reviewers emphasizing that he explains complex medical information in clear, understandable terms and takes time to thoroughly answer all questions without rushing. Patients appreciate that he comes prepared to appointments, having reviewed their complete medical history and recent test results beforehand, which makes them feel known and valued. His positive, upbeat attitude and ability to put patients at ease are frequently mentioned, as is his willingness to listen attentively to concerns. Many patients report having been under his care for 15-40 years and express complete trust in his judgment, with numerous reviewers stating they have recommended him to friends and family.
Patients also share
Very few areas for improvement emerge from these reviews. One patient mentioned that Dr. Shalek could be a better listener and that it was sometimes hard to find moments to ask questions because he talked extensively about non-medical topics. Another reviewer noted that while they appreciate Dr. Shalek's care, his appointment schedule is always very full, making it difficult to get timely appointments, though they acknowledged that competent alternatives are available when he is not. One patient wished he were slightly more outgoing and felt somewhat rushed during the appointment, though they still rated him as a great doctor overall. These concerns represent a very small fraction of the feedback received.
