    I feel comfortable going to this facility. It's embarrassing having to deal with these problems and a lesser organization possibly would have caused me to give up by now.

    I have been treated like a drug addict by numerous doctors since 4/25. I have not had my chronic pain treated and I have actually been thrown out of virtua reconstructive and Rowan neuromuscular skeleton when the doctors refused to see me. My primary took my BP and instead of listening to me that it's high because of the pain I'm in and treating my pain she upped my BP meds. Just because I have history of drugs doesn't mean my pain should be ignored.

    Appointment made in September was never recorded, so I was double booked with another person. I really like Dr. Mammen and will continue seeing him. I feel his office staff needs more training. This is the second time in 6 months that a clerical error has occurred.
