Patients appreciate
The overwhelming majority of patients praise Dr. Giacomo Tomasello for his exceptional listening skills, patience, and clear communication style. Reviewers consistently note that he explains diagnoses, treatment options, and medical terminology in an easy-to-understand way without rushing through appointments. Many describe him as knowledgeable, caring, and personable, with a comforting bedside manner that puts nervous or anxious patients at ease. Several patients specifically highlight that he asks thoughtful questions, involves them in decision-making, and follows up promptly through the patient portal. New patients frequently mention feeling welcomed and well cared for from their very first visit, and multiple reviewers say they have moved family members into his care based on their positive experiences.
Patients also share
While the vast majority of feedback is positive, a small number of reviews point to areas for improvement. One patient felt dismissed and unheard during a visit, leaving in tears and feeling as though their concerns weren't taken seriously. Another single review described the doctor as rude and felt he was dismissive of their own understanding of their body. A third brief review simply stated that he "didn't seem to care about the issues" raised. These accounts are notable exceptions rather than a pattern, as they stand in contrast to the many reviews praising his attentiveness and empathy. Additionally, one patient mentioned a preference for a geriatric specialist rather than a general PCP, which reflects a personal care preference rather than a critique of the doctor's performance.
