Patient Reviews
-
"Dr. Harris is truly exceptional. His bedside manner is unmatched—calm, compassionate, and deeply respectful. He listens carefully, explains thoroughly, and always makes you feel like you’re in the best hands. If it weren’t for his guidance and encouragement, I would have delayed my mammogram and possibly faced a more advanced breast cancer diagnosis. His empathy, attentiveness, and genuine care made an overwhelming time so much more manageable. I’m incredibly grateful for his expertise and heart."

"I’ve been under the care of Dr. Joshua Harris for the past two years, and I truly cannot say enough good things about my experience. From day one, Dr. Harris has shown exceptional professionalism, compassion, and dedication to my care.
He takes the time to listen to every concern without rushing, explains medical information in a way that’s easy to understand, and always ensures I feel involved and informed in every decision about my health. His calm and kind demeanor is incredibly reassuring, especially during times when I’ve felt anxious or uncertain.
What really stands out is not just his deep knowledge of hematology, but the way he combines that expertise with genuine empathy. He treats you like a person, not just a patient. I always leave his office feeling confident and cared for.
The staff at his office are equally wonderful, professional, organized, and always respectful and welcoming.
After two years of consistent, thoughtful care, I can confidently say Dr. Harris is one of the best doctors I’ve ever had. I’m grateful to have him on my medical team and would highly recommend him to anyone in need of a truly exceptional hematologist."
