Thank you Dr Singh for your welcome consideration.
I would recommend him to everyone. Very patient. You need someone like him on your corner
Very kind and professional. He answered all of my questions without judgements.
Very nice and professional
Dr. Singh seems knowledgeable and follows evidence-based protocols closely. My results were reviewed thoroughly, he explained everything clearly, and I left the appointment with a good understanding of my treatment plan and next steps. That said, the communication style was not the best fit. When I asked a reasonable question about part of the care plan, he responded with a lengthy justification that felt more defensive than informative. The question was simple curiosity based on my experience with prior doctors, not a challenge to his expertise. For conditions that require a long-term doctor-patient relationship, communication style matters. He seems competent, but he did not come across as especially warm or patient-centered.
I love Dr. Singh!! He is always very attentive and makes sure I leave with everything I need. It’s hard to find a good doctor but with him I feel like I found the best!
