I found Dr Cohen to be distracted in my appt. He treated my PMR with steroids. Because steroids are toxic to bones, I then had to get Prolia injections. He told me he does not "cure" but only "treats" my illness. That I was welcome to go elsewhere if I felt his treatment was not acceptable. So I did! First I tapered off steroids. I'm now in remission due to another Dr's cure using antibiotics. He is not open minded. He's only looking to make a quick buck. He can't make money off antibiotics!

Excellent experience all around! I am so thankful I found Dr Cohen-Gadol I will be a patient of his for many years to come!

Dr. Cohen and his entire staff are very professional, knowledgeable, and super kind. I have been seeing Dr. Cohen for several years now. He has helped me immensely. The office is clean and beautiful. I never have to wait more than 5 minutes.

My family and I have been seeing Dr. Cohen for years. Even available on the weekends, Dr. Cohen has been there for myself, and multiple family members, with immediate availability for flare-ups. He and his staff are very compassionate and extremely knowledgable, with a variety of on-site treatment options. I thank Dr. Cohen every time I see him and every visit ends with a hug! I refer all of my close friends and family member.

I was recently referred to Dr Cohen Gadol by a friend of mine while I was in town visiting family. The appointment was made effortlessly, and my wait time to see him was about 15 minutes. He didn't hurry me along, he listened patiently to my story, my background and my condition. We talked about my options, he sent me for a test and saw me again the next day. Together we came up with a plan to manage my severe arthritis. The man was genuinely compassionate, & very knowledgeable. Highly recommend

Worst experience of my life, All they wanted to do is sell you expensive supplements. Cohen initially said he would fix me, what a joke. Would not work with insurance. Over changed me for appointment.

took my wife to Dr.Cohen today. Firstly, the front office staff were very friendly and welcoming. Dr. Cohen himself has to be one of the most excellent investigative diagnosticians I have ever come across in my 73 Years on this planet. His attention to detail is quite remarkable and his kind manner promotes the sort of confidence one would always want in a Rheumatologist or indeed any other doctor. Clinical Excellence. Very Impressive indeed.His learned medical standards are of the highest orde

My right index finger was diagnosed by Dr. Cohen as osteoarthritis, I was in agony 24/7. Shaving, tying my shoe, shaking hands, grasping things presented painful challenges. Nothing seemed to help until Dr. Tony Maclouf, a member of Dr. Cohen's group, recommended a shot. Reluctantly I accepted since a previous shot had exacerbated my condition. Wow! Like a miracle! Pain wise I have a normal finger. I'm so appreciative and am enjoying a return to normal use of a hand.

I do not think I was treated like a real person by Dr. Cohen

I would not recommend Dr Cohen. When I first started seeing Dr it was great. Now I make appointments for dr and end up seeing his PA. I have not see the dr. My last 3 visits even though I expressly requested it. His staff is wonderful but within the last 3 or so years so many have come and gone that there is complete new office staff. I never know who will be conducting infusion. Not a good situation. Changing doctors
