[redacted] Dr. Lazarus knew everything about the condition I was sent to see him for. And he was gracious, courteous, spent a lot of time with me, explained to me what was going on with me, changed the medicine for me, and spoke with the specialist who referred me to him. I was very, very impressed with him, and I would definitely recommend him to other people.

The only issue was a miscommunication between the doctor's orders for lab work to be done right there in the clinic and the phlebotomist station. They didn't seem to know I was waiting and 15 minutes later I had to ask the receptionist to find out if they would be calling me soon. The nurse said she didn't know I was waiting for a blood draw.

Dr Lazarus is by far the most knowledgeable Dr I have seen for my issue. He was very warm and welcoming, asked appropriate questions and listened carefully to me.
