David M Kastenberg Md's Online Review Report Card

After several months of declining I finally got him to send me for a test. He & Cheri assured me the test was normal. I did not feel comfortable in their care. They both are arrogant and it’s how dare you question me. Upon finding another GI his test was read incorrectly and I absolutely 100% have the condition him and his nurse assured me I did not. Go with your gut and don’t listen to these two. I never had a pleasant visit with him. The arrogance and incompetence he should have to take classes!

I would give this man zero stars if I could. Long story short, it took him 3 years to finally decide to listen to me and my symptoms and give me a colonoscopy. I was instantly diagnosed with Ulcerative Colitis. Afterwards I had asked him if it would be contributing to my excessive fatigue that I was experiencing. He told me there was no way my UC could cause fatigue because it wasn’t “severe enough”. After trying multiple medications and not receiving complete symptom relief, he told me that as long as I wasn’t bleeding he wasn’t changing my medication. I was still experiencing many other symptoms so he threw random meds at me and said he would never put me on a biologic since my disease wasn’t severe enough. I’ve found another GI and am now on Remicade AND methotrexate. Don't let him make you doubt your symptoms!!!

I have been seeing Dr. Kastenberg for about 5 years. I can say that he is a superb doctor, of the highest caliber, and has done a significant amount to help me through difficult GI issues. He is incredibly caring, respectful, smart and dedicated and I feel fortunate to be among his patients. He is one of those doctors that are quite rare, his patients are lucky to have, and one that other doctors also respect. Great guy.

Told me he that food was not related to Crohn's disease, my symptoms were not related to Crohn's. I asked for a referral to the GI nutritionist - who told me that lots of Crohn's patients DO HAVE FOOD ISSUES and she recommended diet changes that WORKED! I've since left Jeff GI for Marcus Inst, also at Jeff, as they understand auto-immune disease. Once I pushed back about my care the staff became discourteous and multiple faxes from my insurance co disappeared mysteriously.

I have never been treated so poorly as I did by this doctor! He's condescending, did not take my pain or symptoms seriously, the day of a procedure asked me why were we doing it; questioned the legitimacy of my suffering and I had to basically push him to test me for conditions that I ended up having. Stay away from him if your case is not worth of him writing an academic paper.

He explained everything and gives you time to ask questions.

Been my doctor for years, always attentive and makes explanations that I can understand.

I absolutely cannot recommend Dr. Kastenberg enough!

saw doctor twice. first time very nice.took interest.said he doubted i had reflux.sent me for test.i called for explanition of results 5 times never returned my calls.finally had one of his clerks call me to say i had reflux i asked to speak to him about results still waiting.never sent records to my local docs.his office mananger heather is worst!

Brilliant man. Considers whole patient health when diagnosing, isn't myopic. Creative problem solver, compassionate, good eye contact, takes time to actually hear what patient is saying and can hear between the lines to consider emotional and physical well being of patient. He participates in research, trials and is ahead of his game. I wasted many years going to several local gi's in nj and then Dr. Kastenberg was able to cut through the clutter of all their b.s. and their misdiagnosis' and he easily honed in on my problem. On the down side, he is very busy and I believe he can use a stronger office staff to improve patient followup correspondence and make subsequest visits.
