I would never recommend Walmsley to anyone. He was treating my husband for low grade cancers of the bladder when he discovered one too large to be removed as an office procedure in July ‘2020. Would call my husband later when he could remove it, no worry, low grade. Two months later my husband had called Walmsley several times complaining of severe pain right side near kidney but lower. Walmsley did a sonogram, reported everything was fine. Pain became worse, we ended up in the emergency room in September. Due to Covid we sat for more than six hour were never seen, decided to come back later. Called Walmsley he recommended we see a Gastronomic Dr., so we did, tried different dents remained in severe pain until Walmsley called to remove the tumor he had found in July, it is now Dec. 15. Called us in for a visit Dec 23rd, did not do a biopsy on tumor in July was not aware it was a very aggressive cancer, could not be removed,had wrapped itself around the ureter to his right kidney, killing his kidney (all the pain). Had grown outside the wall of the bladder and leaning against his Iliac artery. Also created a large blood clot that went from his groin to his knee. Now could not walk. If he had done a biopsy……..or read the sonogram. He would have know back in July and September that things were serious. He did not do his duty as a Dr. My husband died nine months later.

I have been seeing Dr. Konstantin Walmsley for 12 years and he is the best from all doctors
I ever had. He explained everything in details, very professional and knowledgeable.
I went through few tests and surgeries with him and performance was excellent.
My wife is planning to switch insurance to get opportunity to cure under Dr Walmsley.
I would strongly recommend him to everybody.

Dr Konstantin Walmsley is a great doctor. He is knowledgeable, professional, and I feel genuinely cares about his patients. I had heard such good things about him that I switched my insurance just to see him. It was definitely worth it. I was very anxious about a diagnosis and if I would require surgery and he was very calm and down to earth. I wasn't worried anymore and thankfully I didn't need surgery after all. He sent me for a test. I went to mountainside. They were great there. He's a gem in Essex county. 👍

I have been seeing him for over ten years and is by far the best Dr I have ever had ! He's a caring Dr that takes time to see each patient I have witnessed that ! He is also an expert in his field.

I was bleeding profusely after a TUNA procedure. I called on Wednesday and his partner Dr. Sahidi told me that I should call Walmsley the next day because he would be in. I called him Thursday and Friday and each day his staff told me that he would call me back. He did not call me back until Monday or Tuesday. When he finally returned my call, after the bleeding had slowed down, he never apologized; he said he was "very busy"! The man is worthless if you have a problem or a concern.
