If old arrogant egotistical , past their prime, physicians is your thing, then by all means. At one time he may have been great, and is respected in his line of work, but this guy needs to stop seeing patients, andretire to Boca Raton FL and spend his days playing golf.

Dr. Kasper was incredibly thoughtful in his prognosis, and never made me feel rushed. He took time to re-assess my symptoms and compare it with my past medical history to better understand my complaints. He was very kind, and listened toeverything that I described to him. I would highly recommend Dr. Kasper.

Upon arrival the nurse said that my zocdoc appointment never registered in their system. All of the paper work that I filled out prior to going was not there which caused me to have to fill it out at the office. I am currently 8 mos pregnant and took my 3 yr old daughter with me to the appointment. Which lead to a complete disaster because of the ridiculously long wait time. We arrived at 8:57am ... We were called in for preliminaries around 1030, we were then placed in a 2nd waiting room to wait for an available room which did not become available until 11:30. We waited in two different waiting room for over 1 hr each!!! Totally unacceptable. People that arrived in the "2nd waiting room" after me were seen before me. I totally could not understand their process when it came to calling patients. I had to approach one of the nursing staff member to inquire as to what was taking so long because I was becoming hungry and needed to eat. The visit was about 15-20 mins with the dr.. The dr was nice but a "sorry for your wait" would have made things just a little better. I would think twice about going back. One of the reason why I chose him was because of his experience and credentials however no one wants to spend half of their day in a dr.'s office.

I happened to have my first visit on a day where only one physician was in and apparently a lot of emergencies. I waited an hour and a half before being brought into the exam room. Total time spent in theoffice was about 2 hours. The doctor spent some time with me but obviously mostly rushed in which case I didn't feel comfortable asking in depth questions. I will schedule my next appointment a year from now and hope for a better experience. The staff was very friendly and apologetic about the wait time.

The two ladies in the front desk are very rude and unprofessional. I drove from very far to come see the doctor and they didn't even check my Medicaid insurance in advance to see if the office accepted it. When Itold them they should check patient insurance before confirming the appointment they were very rude about it. They both started yelling and arguing with me. I wouldn't let both of them be in the front desk greeting patients if I was the doctor because they have low customer service skills, their attitude stinks. right when I was waiting one of them was being mean to an old lady. They both don't belong in a front desk talking to patients.

The wait was over an hour and they overbooked the office to get in patients because the doctor was going on vacation the next day. Also, they took in patients that walked in when they were already overbooked.

I really like Dr. Kasper, so I didn't care too much about the wait. I know that he does a very thorough job and that that would sometimes make his wait times a bit longer. He waived my co-pay because of the wait as well!
