    Horrible experience at this office. Had an appointment at 2pm on Thursday, when I arrived I was told my appointment was the previous day. In preparation I had to complete 2 enamas and am 27 weeks pregnant. On Thursday evening I received a call from their automated scheduling system that I had missed my appointment scheduled for Thursday afternoon at 2pm. Obviously the staff and doctors have no care for their patients or their time. Never going here again.

    Arrogant! Rude. No bed side manner. 55 year old man who needed a second opinion and he talked me down. I spoke up firmly, and his staff knew I was right. They didn't say a word and walked away.

    I had colon resection by Dr. Marks. This was a difficult surgery. My local surgeon wanted to continue treating my many attacks with medications. On one hospital stay another surgeon recommended I see Dr. Marks. Best move I made concerning my on going battle. Did not like the long drive but it was well worth it.

    On August 4th, I made an appt with Patricia for Sept 6th at 2pm. She provided general directions and mentioned they’re in suite 375. I scheduled a day off from work due to the long drive (1 hr 30 min one way). Around 1:50pm, I called about being a little late. To my surprise, the front desk couldn't find my appointment. They couldn’t even find my record. The front desk and office manager Krisanne were rude. Dr. Marks refused to see me b/c he was busy. Good to know he cares and values my time.

    Dr. Marks was recommended by our gastro doctor Dr. Lubich in south jersey . My daughter Shannon Campbell was treated with a successful surgery by your facility at Lankenau. Our entire visit was a very pleasant experience. We thank you for the care and compassion that was shown to our family. We know we were in the best hands in the world by being sent to your hospital. God bless you and your staff. Sincerely . Sue Dickinson, a very happy mother.
