The doctor knows his stuff but the receptionist is extremely rude. I had an incident where I called and she hung up on me over a discussion . I dislike the fact that the waiting time is almost 3-4 hours even if you make a appointment.

He's a great doctor, he takes his time with every patience. He is very professional and makes sure he answers all your questions.

Absolutely unimpressed. My mother has been going to this man for decades and frankly I've had enough. Dr. Lefevre decides to call my mother to inform her that her sugar levels are above 600 and she needs to go the ER - 24 hours after she was in his office. Whom in facts gets lab results within a 24h hour span. I can't prove it but my assumption is he did the test in the office and didn't read it until the next day. She could have gone into a diabetic coma. I'm done with him. Look for a new MD

I was a patient of Dr. Lefevre, he sent me for labs and I had an A1C of 8. Which means I am diabetic. The office did not call to notify me of this serious disease. I only found out over the phone a month later. He gave a script for a meter, asked if I wanted medicine or to manage on my own and told me to see him a month. I was devestated, especially since I was TTC. Needless to say I switched PCP and am now getting adequate care.
