Jonathan E Kass, MD

Love Dr Kass and will continue to be a patient here after his retirement

Dr Kass was very informed about my care and was patient and courteous to me and my son. I will miss him dearly.

A good visit.

I wish Dr Kass a very wonderful retirement but I'll miss him! !

It was great

Dr Kass is always concerned about issues affecting his patients. Hope he enjoys retirement.

I was very concerned that I might have lung cancer. Dr Kass saw inflamation on my CT scan, and his 42 yrs of experience and the tests that he ordered have so far proved him right. Still waiting for more results so we can make a plan going forward to treat these symptoms.

Both at check-in and check-out, the staff treated me very well. That shows they've received good training. I know some patients are rude, but not everyone is like that. And some of the assistants can be rude, especially if they don't understand the pronunciation. But I was lucky with the two staff members I had yesterday; they were professional.

Dr Kass is the best and gives us wonderful care. We will really miss him when he retires, but pray he has a great retirement!

Very happy with Cooper staff and facilities

I'm very happy with my provider and all the staff.

Dr Kass is always ready to offer welcome advice on how to improve my cpap usage. He definitely understands the stress and even discomfort of dealing with both types of Apnea which I have!

I must say all of my contacts at Cooper have been excellent.

I was very comfortable through the whole experience & procedure!

I can't say enough good things about Dr. Kass! Copper University Health Care has a real asset in Dr. Kass!

I always rave about Cooper and recommend them as a place for care. They're kind and patient and try to work with you. I think it's great they have multiple avenues of communication from calling the office to just messaging on the app.

All was good!

Dr. Kass is awesome and caring.

From the front desk, to the medical assistant, to my doctor, and ending at check-out, everyone is nothing short of kind, respectful, and attentive.

Everyone was cordial, helpful and sincere in their interactions with me.

He had no appointments for months and then I received a call saying he was opening up a day to work in many people - I was able to get one of those appointments. He really helped me out by opening up those appointments.

Professional, knowledgeable, great listener!! !

the Doctor listen to my concerns and the help me decide

It was awesome

Yes, the provider, Dr. Cass, is a great physician. I love him and he's very caring and do good with my son when he comes to his appointments and trying to resolve all his needs for him to get the CPAP mask and any other problems and issues that he have for breathing. He's a very concerned doctor and very good doctor and love him. because I like the older doctors anyway, and I'm glad he's still in business and around. And I will refer him anytime to anybody because he's very thorough, also very thorough, very thorough person. Hard to find good doctors like him anymore. So yes, Dr. Cass is great. And would love to give him a good survey. This doctor, physician, treating patients, great man. We need more doctors around again like him. Thank you.
