in Trenton, NJ |
Had an appointment that I scheduled 2 months in advance. Secretary called me the day of the appointment to cancel. She then preceded to tell me that my appointment would be rescheduled in one month, without looking to find one for sooner. She was rude and seems to be every time I call. Terrible customer service.

I have been a patient of Dr. Jass for over 25 years. What I value most is his dedication to finding answers and his love of investigating alternatives. He discovered a potentially dangerous condition that my husband had that had been undetected by his previous physicians. He also handled a mental health issue with my son with incredible understanding.

Dr. Jass is an excellent, informed, smart, dedicated healer who takes a holistic approach to health that includes diet and lifestyle, unique in my experience. He does not jump to the prescription pad, he's open to natural remedies and he always cites journals and studies. There are frustrations - waits are long and appointments not always available (though day-of appts are accommodated for emergencies). I feel very fortunate to have found Dr Jass because this type of doctor is really rare.

Was scheduled for a physical exam. Waited 45 minutes only to be told by Dr. Jass that he would not perform a physical, and would only give me a consultation that day (despite not being told this when I made an appt). Physical would cost another co-pay. Spent 10 minutes discussing my health, and was dismissed. Later called for a referral to a dermatologist, and was told he would not provide it without having me in again. To boot, there were e-cigarette ads in the waiting area. Dishonest.
