only doc who got me or took time to try. I'm better than I've been in a long time. Get over your hang ups and stop reading reviews. This doc is the real deal.

More than just competent, qualified and caring. Gets to the point quickly and didnt allow me to waste time and money. Accommodated my schedule, incorporates family which no one cared to do up to this point. Negative reviews are unfounded - all my therapists knew of and highly rated this practitioner. Does not addict you to other drugs like most docs will.

Do not see this doctor. If you can't show up with money every 10 days he drops you and lets you suffer. Stay away! He is not in it to help you. He is in it for money. He can only prescribe to a limited number of patients by law. As soon as you want to taper off he starts looking for a reason to drop you cold.

Excellent expertise in drug field; very caring
