Dr. Arena treated me in the hospital while I was there for an emergency admittance for a GI issue. She is absolutely wonderful! She is so so kind and has a wonderful bedside manner. She did an endoscopy on me and I had no sore throat, gas, or any bad side effects. She was able to find and diagnose my issue and give me proper treatment which aided me in finding relief from the pain I was having. I am very thankful to Dr. Arena and even though Glen Ridge is quite out of the way for me, I have decided that I will call her office to follow up with her instead of using another gastro doctor that may be closer to me. Thank you very much Dr. Arena!

I love Doctor Arena . She is so kind and takes time with you. She help me with a problem that I could have died from. I go to see her every few months to make sure I’m doing ok. God Bless her. She is a wonderful gastroenterologist. I wouldn’t see anyone else.

Dr. Arena has a great chair-side manner and she thoroughly explained the procedure. I would definitely recommend her to family and friends.

Dr. Arena was very interested in the facts I presented as far as my health complaints were concerned. After my procedure, she explained a few things to me . Within a few days, she received the lab results and gave that information to me. I find her to be very thorough and has a sincere interest in her patients. Dr. Arena is the BEST!

Dr. Arena has been treating me since early May of this year. Not only has she been a tremendous help getting me through my treatments, her attitude and demeanor gives me a lot of confidence in her abilities and insight to getting me well. Her staff has also been nothing but kind and helpful. I would not hesitate to recommend Dr. Arena to any friend or family member.
