I cannot say enough great things about Dr. Christoudias. He is not only an excellent surgeon who performed my hernia operation. He has since graciously agreed to see me whenever I have had any abdominal health concerns and has provided me with extremely thoughtful and helpful recommendations. He is clearly a doctor who cares very much about his patients and people. Toni Ann and Janina are also awesome!

I cannot recommend Dr. David Radvinsky highly enough. I saw him initially at Chilton Hospital and followed up with him at his office afterward. He is very concerned, attentive, and professional. I would recommend him to anyone looking for top-tier medical care. His office staff was also very helpful and quick to get back to me after I inquired about an appointment.

Dr. Mansouri is an exceptional, dedicated, and compassionate physician. His professionalism is deeply appreciated. He operated on my husband twice, and both surgeries were successful. I am 73 years old, and I have never met a surgeon like him. He always seeks the best for his patients. The office didn't have an immediate appointment, so I had to call him and explain my urgency. Despite his busy schedule, he was able to see us quickly. As always, he was very attentive and, despite his tight schedule, attended to us immediately. He is an angel. We could hear him explain clearly, outlining three well-defined plans for the operation. After the surgery, Dr. Mansouri gave us clear and precise instructions that allowed my husband to effectively manage his health. Dr. Mansouri was completely dedicated to the follow-up, answering all our questions and providing my husband with the best possible care. I recommend Dr. Mansouri without hesitation. Thank you so much Dr. Mansouri for the difference you make in the lives of your patients, your kidness, sincere caring and being so skilled at what you do makes everything better. Thank you so much to Adam Adrinelli, Physician Assistant A++.GOD bless your hands Dr. Mansouri to continue saving lives.

Highly Recommend Dr. Radvinsky, performed a gallbladder removal surgery on me after I was admitted to the ER at Pascack Valley Hospital. Dr. Radvinsky came in before surgery and explained the procedure. He has a great bedside manner and was prompt with the post-op appointment.

Kind, compassionate problem solver Dr Mansouri has a special mix of Kindness, Compassion, Calmness and Creative Intelligence. He has also built a staff with those same qualities including his PA Adam, Tara at the front desk who pleasantly cared for all my administrative needs and Mekalia his Surgical Coordinator. In summary what a great, efficient, compassionate team. Dr Mansouri found the causes of my multiple problems that 4 other experts had missed. He performed Robotic Laparoscopic surgery on me successfully. All I can say is God Bless Dr Mansouri and his staff, thank you for helping me when no one else could.

I was admitted to ER in terrible pain due to perforated colon from diverticulitis & sepsis. Very frightening for me but he was self assured & I just knew I was in good hands and I was! Woundup with colostomy, parastomal hernia, umbilical hernia, & inflamed appendix! I had complicated situation also going thru steroid withdrawal from severe skin issues for yrs. Dr Radvinsky was with me every step of way till I was well enough for colostomy reversal; no words for my gratitude, he’s my hero!!! The entire staff is awesome as well, God bless

Hospital stay Doctor Mansouri and his PA Adam treated me at Valley for appendicitis. Both were extremely knowledgeable and patient, willing to explain everything, and gave me peace of mind. I wanted to express my sincere thanks to both of them for my care.

amazing doctor! I was admitted to the ER a few weeks after a hysterectomy for localized pain. I was terrified when I was told I needed an emergency appendectomy since I was still recovering from a major surgery. Dr Radvinsky was SO kind and reassuring and patient with all my questions ( and tears). It's so rare to find a surgeon with this kind of bedside manor and empathy. He is a GEM! My experience with him and this surgery was truly seemless and he is a wonderful Dr!

I had my gallbladder removed by Dr. Radvinsky last week. His positivity, bedside manner and how soft spoken he is made me feel at ease pre and post op. Dr. Radvinsky explained what they would do, what could happen, what I should look out for, recovery time etc. He was super thorough and answered all of my questions. I was experiencing a lot of pain during a consultation visit and Dr. Radvinsky went above and beyond to make sure that I was seen and taken care of at the hospital. My gallbladder had to be removed and he was by my side the whole time. He showed up post op (it was thanksgiving week) to make sure I was ok and called me even on the weekend (on the holiday) to check in on my recovery. I wish that I could have Dr. Radvinsky handle all my medical issues because you can tell that he truly cares about his patients. Super grateful to be in his care and look forward to my post op visit. Would 1000% recommend Dr. Radvinsky and his group.

Amazing, Gifted, and Gentle Doctor!!! I have been a patient of Dr. Mansouri for about 4 years due to internal hemorrhoids which he has treated with rubber band ligation which is fairly painless and quick. He is the first rectal specialist who DID NOT suggest hemorrhoidectomy and I am so grateful. He is very, very gentle and is constantly assessing during the procedure my level of discomfort. e takes the time to answer all questions and concerns. Really don't bother seeing anyone else...he's the best and again incredibly gentle.

I recently responded to the Valley Hospital Emergency Room with abdominal pain. I soon learned that my gall bladder would have to be removed. Fortunately for me, I was referred to Dr Christoudias. He ensured that he and his team would treat me in a timely manner and take care of all of my medical needs. He, Dr Marta, and their team were kind, considerate, caring, and professional. Took the time to explain the procedure and had great “bedside manner”. May nobody ever need a surgeon, but if you do - I highly recommend Dr Christoudias, Dr. Marta, and their team

I went to Dr. Christoudias after it was determined I had an inguinal hernia, but both my primary care physician & the surgeon he referred to me had no real expertise with regard to laparoscopic diagnoses. Not only was Dr. Christoudias informative about my condition & explained in a way that was easy to understand, but he was able to get me into surgery in a timely manner. The surgery was performed flawlessly and my after surgery check-up with him showed no signs of the hernia coming back. It was comforting knowing that I was able to find a surgeon as qualified as Dr. Christoudias was in making me healthy again.
