Patients appreciate
Dr. Giacomo Tomasello receives overwhelmingly positive feedback from patients, with the vast majority of reviews praising his attentive listening, thoroughness, and clear explanations of diagnoses and treatment plans. Many patients specifically highlight that he doesn't rush appointments, takes time to understand their concerns and medical history, and answers all questions patiently. His warm, personable bedside manner and sense of humor are frequently mentioned, as is his knowledge and ability to explain complex medical information in an easy-to-understand way. Numerous reviewers, including new patients and those establishing care after moving to Texas or switching providers, describe feeling comfortable, respected, and confident in his care, with several noting they have moved family members to his practice as well.
Patients also share
While the vast majority of feedback is highly positive, a small number of reviews point to areas for improvement. One review (1.83 stars) described the provider as rude and felt he dismissed the patient's own understanding of their body. Another review (2.57 stars) reported feeling dismissed and unheard during a visit, leaving in tears, though the reviewer noted his medical assistant was kind and compassionate. A separate review (3.4 stars) similarly felt he didn't seem to care about the issues raised. Additionally, one reviewer (3.92 stars) mentioned a preference for a geriatric specialist rather than a general PCP, which reflects a specific care need rather than a critique of his performance.
