Dr Weinfeld is thorough and detailed. He prepared a day ahead for my visit, went over everything in in my history and with my current status with a fine toothed comb, ordered blood work which I got immediately, referred me to another doctor, which happened immediately, called me the next day to go over my blood work, suggested a change in medication dosage, and called in future blood work. He remembered details I told him about specifics to my preference for minimal medications and applied all that my husband and I mentioned to the fine tuning of my care. I arrived to the appointment with high anxiety and returned home without an ounce of worry. We are set for future tears and appointments. No stone was left unturned. I am blessed to be Dr. Weinfeld's patient. He is the best( along with Dr. [redacted]). The finest physicians in the world.

Dr. Weinfeld was absolutely amazing. I went in. I have absolutely no risk factors for cardiovascular disease. And I went in because I had been feeling some mild chest discomfort when I worked out, but then it would resolve. I assumed he would just send me for a stress test or I don't know. And he actually said, based on this EKG, I think it's really important that we send you in an ambulance to mass general Boston. Um, cause I'm very concerned by how this gives you locks. I don't feel comfortable with you driving home or spending the weekend by yourself. Um, and I ended up being transferred here. I'm still here. [redacted]
