Kevin J Callahan, DO

My visit to Cooper was excellent. The service was great from the check-in and the check-out, the meeting with Dr. Callahan. Everything was explained to me. He listened to what I had to say about my health and he was very tentative to my medical needs. Everything was great.

Have always been seen in a timely fashion, and I feel the doctor knows what he is doing. Can't ask for more than that!

Hi, Dr. Callahan is extremely professional. He knows just what questions to ask me and how to respond to my answers. I have never had any problems with Dr. Callaghan and I hope that I can continue to be one of his patients. And if anybody else has a problem that he is one of his expertise, I would definitely recommend him.

Love working with Dr Callahan on maintaining my chronic leukemia.

Dr. Callahan is the most respectable and honest doctor I have ever met. He cares about me and this is what I like in a doctor. He's also considerate, knowledgeable, and very caring. I really love Dr. Callahan and he's always been in my corners for the years that I've been with him. Thank you.

Dr. Callahan and the Cooper staff are wonderful!

Dr. Callahan is awesome

Everyone was very personal and very courteous Helped in everyway they could

I am fortunate to have Dr. Callahan as a very good doctor. He always explains in depth what he would like me to do and expectations for the next visit. I am fortunate to have a doctor like Dr. Callahan that has great concerns for my health. He explains the future goals on maintaining my health. He doesn't speak to me in Dr. jargon he communicates with me on a level that I can understand.

This doctor has no room for improvement. He is my favorite doctor. He's very kind. He's very considerate. He has an amazing bedside manner. He's very thorough. I cannot say enough about him.

Dr Callahan is a very kind and compassionate person. He always makes me feel very comfortable.

Dr. Callahan is one of my favorite doctors. He's always considerate, explanatory and giving health care advice.

Always a good experience. Love the staff/physician

Provider was amazing, staff was amazing, people that checked me in were amazing, everybody was friendly, awesome doctor. The only issue I have is trying to get a human being when you call the general number. And that is the only issue I have. You have to jump through hoops just to get a human, but once you do, everything's great.

I recently saw Dr. Callahan for a second opinion and was extremely impressed with the level of care I received. He was very thoughtful, thorough, and knowledgeable. It was clear he had taken the time to review my records carefully before the appointment, which made our discussion much more productive and reassuring. Dr. Callahan listened attentively, explained everything clearly, and made sure all of my questions were answered. I felt comfortable, respected, and truly heard throughout the visit. I left feeling confident in his expertise and grateful for the time and attention he provided. I would highly recommend Dr. Callahan to anyone seeking a physician who combines deep knowledge with genuine compassion and professionalism.

can't say enough all's good

Everything about Dr. Callahan is outstanding

Excellent Visit , Like Always

Dr Callahan is a wonderful doctor. He explains everything!! !

I was even impressed with the kindness and compassion of the person who checked me out.

This was the first time I saw Dr. Callahan. He is an excellent health provider, explaining all the pertinent information and he is very kind and knowledgeable. Thank you so very much, Dr. Callahan!!

Dr. Callahan is one of the best doctors that I've ever had. I would recommend him and his staff to anyone who asked if I knew anybody.

Since I have to be going to an oncologist Cooper is the place I want to go and Dr. Calahan is the oncologist I want to see

Thank you very much. I can see your concern for my best treatment and health. God bless .

thank you

My experience w/ Dr Calahan is exceptional.. and indeed , all staff , as well I am soo delighted only because .. the rest of my experience ( in general ) has NOT been so great or consistant .. So , I would recommend Dr Calahan and his ( including staff) all day long .. but " overall" Cooper is "Not ( overall ) consistant" I cannot recommend Cooper ( in general ) . I can and would recommend Dr Kevin Callahan , for sure ..

Dr. Callahan is cordial, professional and extremely knowledgeable. I live in Philadelphia, a city with some of the most prominent physicians, and yet I still travel to Voorhees to see him. That fact should say it all.

Always treated me with dignity and respect and made me feel comfortable

Dr. Callahan is very attentive. He listens and very informative. Very kind and caring. Would recommend him others.

Always have a good professional experience.

I've been seeing Dr Callahan for a lot of years. He is a very care. He treats me like he would treat a family member. I have a lot of respect for him.

All the people I encountered at Cooper Health were very professional, very friendly, and just great to deal with. I could not have asked for a better care.

As always I enjoyed my visit!

Great experience.

Dr. Callahan is an excellent physician who always takes time to talk to me and make sure I understand the results of any test he orders. I trust him completely with my care.

I can't find one thing to address that would need improvement. Everyone is a 10. So caring and efficient!

My expierence with Dr. k Callahan was wonderful. I went for blood work at cooper labs and I am awaiting my results be be posted. Hope that are posted soon. Kind regards.

It is always a pleasant experience.

Everyone is very nice

Doctor has a great personality! He also was very honest and up front.

I met Dr. Callahan for the first time in the hospital about a month ago and I had a follow-up visit yesterday, he's a very nice and pleasant person to deal with, no complaints from me. Thank you! Gaëtan C

I just love my Dr and trust him with my health issues.

Always a pleasurable experience, from the staff person at the front desk, through check in, the examination or procedure, to check out. Cooper is the best! !

Dr. KEVIN J. CALLAHAN took care of my sister when she had terminal lung cancer. He treated her with dignity and care. When I needed to find a hematologist, I knew I wanted him as my doctor . I trust him 100%. He is knowledgeable, thorough, and caring. 10 stars!! !

I can't say enough good things about Dr. Calahan. He's is always in a great mood and that transfers to my wife and myself. He's always positive and I've said it before, if I had gone somewhere else for treatment I don't believe I'd be here today. Dr. Calahan and his entire team have been there for me for over 3 years now. I had a minor setback in march, a mass was found behind my sternum and I had to get a biopsy which although very small it was non small cell like I was being treated for. Up to that point every CT scan showed nothing but scar tissue and I was doing well on keytruda. Even though it was very small, I had to do 10 radiation treatments. It took a lot out of me and I lost weight. Now I've got my appetite back and I'm putting the weight back on. All in all I'm very happy with Cooper and especially Dr. Calahan.

I like how cooper doctors stay on top of everything

I have been seeing Dr. Kevin Callahan as my oncologist, coming up on 6 years this August. I have a rare blood abnormality but Dr. Callahan has always been there for me regarding office visits, medications, and my personal fear about this chronic condition. He has guided me in how to proceed with required bloodwork and also with how to understand my various numbers regarding bloodwork and platelets. If I were not a career musician I would be entwined with the medical field because this weird condition of mine has intrigued me from my diagnosis back in 2019. Thank you, Dr. Callahan for your humor and knowledge. It calms the patient out there every day. Cooper Hospital is blessed to have him on the hematology / oncology medical team, as well as his top-notch nurses and office assistants.

The very best Everyone treats me with courtesy and compassion

This provider is the best I have ever had a pleasure of meeting. Excellent care and very easy to talk to. The staff here at this provider is excellent! I can't wait for my next appointment. It made my day!! !

Just had to wait approximately 30 minutes from appt time. Which is unusual for a specialist.

Dr Callahan was informative as usual and answered all my questions.

I look forward to my follow up meetings with Dr Callahan. He follows what is going on with me and other Cooper doctors and treats me as a whole patient. I honestly believe he cares.

Dr. Callahan has been my doctor for many years and he always explains everything so that I can understand my treatment and how it is progressing. He answers every question with patience and makes even complicated medical procedures more simple, so that I can make decisions. I am so grateful to be in his care.

Hello, Dr. Callahan was excellent. His staff is excellent. That's all I have to say. Goodbye.

Overall great experience as usual. Dr addressed with me all of my concerns. Office experience is always pleasant!

from the time we arrived at the front door the gentleman grabbed a wheel chair me, the check in & check out everything was done like they just liked helping people.

I have been a patient of Dr. Kevin Callahan for almost 19 years. He has been a wonderful caregiver in every facet of the treatment of my blood disorder. I cannot say enough good things about him.

Entire visit went very smoothly. Left with a good feeling.

My experience with this doctor has always been caring and cordial. Over the years my experience with Cooper has always been at the highest degree. I always recommend Cooper to any of my friends with medical problems.

All of the staff and provider were very accommodating. Parking, however leaves a lot to be desired. Very few spaces available at 9:30AM

I had a severe infection and everyone I saw whether it was Cooper or Virtua everyone treated me with kindness and helped me through a very hard time Thank you very much
