I do not like him at all. I did not like being in the room alone with him. I do not trust him. He is very rude.

I have seen Doctor Glassner for about 8 years, to long. He is the most arrogant person I have ever met . Don't go to a med clinic as his patient he will reem you a new one every time. I have chronic asthma and the man has never listened to my chest. This last time I went in having bowel problems due to the antibiotics my asthma allergist put me on, already had cdif twice and thought I might have it again.He starts screaming at me saying I shouldn't go to a medic clinic which I didn't and when I let him know I didn't he got nasty with me and my wife then slammed the door when he left. I sorry I am 52 years old not a child .i would not recommend him to my worst enemy.

Dr. Mark Glassner is almost a family retainer. He's seen to th health needs of three generateions of our family, and I coudn't be happier with his care. his practice is frequently used as a teaching practice for family medicine - he's *that* good. We're extremely pleased with him and ihs practice partners. The only down-side is that he's so popular that scheduling can be a bit tight.

Though it is true that late in the day wait times can be longer, get an early appointment and that won't be an issue. Realize that things happen throughout the day that will push back everyone's appointment.Overall a very nice and caring. I've been very happy with him over the few years he's been my doctor.

Love Dr. Glassner! He is a great Dr. His staff at the window leaves much to be desired but once you get past them, you're good to go!
