Patient Reviews

  • "I really felt at ease with Dr. Rubin. He has an “excellent bed side manner” . Dr. Rubin explained everything thoroughly to me. Explained why I had nothing to worry about. He is open, honest, knowledgeable, and wants you to feel safe. His front office staff are great. They are friendly and respectful. His mother is also a doctor in this practice. Judging how my visit went I feel safe to say either doctor will give their all for their patients. Do I recommend this practice:YES"

  • "Clean office, friendly staff, and great doctor who thoroughly explained everything I needed to know about why I was in that day will definitely return! Wait wasn’t too long and New patient paperwork took a little while to fill out because I think they meant to send to me ahead of time but did not. Overall awesome experience!"

  • "I’ve been a patient of Dr. Rubin’s since 2019, when I switched to his care during my ongoing battle with leukemia, and it has been one of the best decisions I’ve ever made. From the moment I became his patient, Dr. Rubin has gone above and beyond—not just in managing my treatment but in providing emotional support and care that has made all the difference. Dr. Rubin’s knowledge and attention to detail ensure that I am always receiving the best possible care, and his ability to explain complex medical information in a way that’s easy to understand gives me such confidence in my treatment plan. What truly makes him exceptional, though, is how personal and compassionate his care is. He takes the time to connect with his patients on a human level, making me feel seen, heard, and cared for in ways that go far beyond his role as a doctor. I’ve always been incredibly sensitive to blood tests—a challenge that could easily cause frustration—but Dr. Rubin has been endlessly patient and understanding. He takes extra time to make sure I’m comfortable, offering reassurance and care that have eased so much of my anxiety. Dr. Rubin’s incredible team also deserves recognition. Every member of his staff is kind, professional, and efficient. No matter how big or small my needs have been, Dr. Rubin and his team have always been on it—quickly, efficiently, and with so much heart. It’s clear that they are genuinely invested in the well-being of their patients, and that level of dedication has made an enormous difference in my life."
