Kevin J Callahan, DO

My care was provided efficiently and I was informed about my care.

Dr Callahan and his office are exceptional! !

Dr. Callahan was very easy to talk to. He made me feel very comfortable and answered all my questions.

I really like Dr Callahan he doesn't speak doctor teams. It makes everything that I can understand and I follows his instructions on what I need to do. Every visit keeps getting better. I'm so h grateful for him.

It was fantastic. There was not a person there who was not very good. And it was charming and it was wonderful and I came out feeling a whole lot better.

Yes, I'm very happy with Dr. Callahan. He's very interested in his patients, gives great advice. I just love him. Thank you.

All positive-Dr. Callahan made my situation & diagnosis easy to understand & was kind & personable

It was a great experience.

Excellent service! !

It's always a pleasure to see and talk with Dr. Callaghan

My First appointment with Cooper University Hospital I have excellent experience and quite happy

Extremely professional from beginning to end. The very best?

Dr. Callahan is extremely professional, efficient while simultaneously, extremely personable. All that one can ask for in a doctor.

my experience with Dr. Callahan is always exceptional. He knows my files before he walks in. He explains everything to me and it's fun to talk to and at the end of this visit this time the person in the office was very very, very pleasant and fixed something for me.

Dr. Callaghan was most gracious and he always takes very good care of me and the staff as well was very, very well informative and caring. Thank you.

Everything went very well

Everyone, from intake, to the nurses, to Dr Callahan, to the scheduling clerk all treated me with courtesy and respect ! I always sing their praises and recommend Cooper to anyone who needs excellent treatment!! !

Dr. Callahan is very professional and very caring and explains everything very well and I'm very lucky to have him as my doctor.

Dr. Callahan is awesome

Excellent care.

Everyone is very nice

Dr Callahan's very nice person to deal with and also the rest of the staff.

Dr Callahan is fantastic! He explained all my tests thoroughly and made me feel well cared for with him. His staff and the receptionist were very supportive and nice. It is good to see friendly smiles when going to a doctor. Cooper has the best! I changed all my doctors to Cooper doctors and have been very satisfied.

Dr. Callahan is a well-informed, gracious and caring person. I trust him fully as I do all my Cooper doctors. I love Dr. Callahan.

Dr Callahan and the staff were exceptionally courteous & professional.

No improvement needed. One of the best doctors I've ever seen in my life and the best office staff. Everybody was lovely.

Some kind of wonderful

My doctor was very informative.

The overall experience was excellent. When I checked in, I was instructed to sign 2 (actual) paper forms- like a "Just in case" consent, "in case" the doctor sent me outside of Cooper - a release of records. I did not want to sign it, but I did. I don't know why this needed to be done - it should be on a case by case basis, after the visit, if it's actually necessary. I did feel a little uneasy about signing them.

Staff was very apologetic about my 30 minute wait because a room was not available. When I saw Dr. Callahan he was also very apologetic. He took his time and we talked about my problem and made it easy to understand.

Dr. Kavanagh showed great knowledge and respect and was definitely one of the best doctor visits I've ever had. Thank you.

Cooper has a great staff

The people and the Doctor made me feel that my health was there first priority!!! And I Thank them all!! !

As always, I was highly satisfied by the care I received.

Everyone is wonderful in Dr.Callahans office. I'm in good hands

Dr. Callahan was excellent, thorough, and very friendly. And I also want to recognize April, who was from the get-go as she walked in the room, was very pleasant, kind, and also very thorough. Thank you.

Dr Callahan has a great bedside manner. He listens, patiently answers questions, and never once made me feel rushed or a bother.

Everything was great

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.

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.

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.

It was very positive.

Satisfied with my experience and understanding the process of being healthy and how the therapy would help me.

He's great Dr! !

Dr. Callahan is awesome

The first time I met Dr Callallan I like him he is a very very nice man hopefully I will be able to keep him as my Dr! !

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

Dr. Callahan is excellent

The best. Dr Callahan and staff are awesome.

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.

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.

can't say enough all's good

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

Excellent Visit , Like Always

Everything about Dr. Callahan is outstanding

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 ..

The whole entire team was great from Registration, MA's and my Dr. Special shout out to the young lady who roomed me, she explained she was new...Kudos for Cooper bringing her aboard! :)

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

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

I just love Dr. Callahan, DO. He spent a lot of time explaining some of my test with me so that I had a better understanding of lab results. Looking forward to my next visit in 2 months.

Everyone is very nice

It is always a pleasant experience.

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

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

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.

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 Callahan is very through and explains everything so i understand. I very much appreciate him being my Doctor Tom

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.

I have been seeing Dr. Callahan for over 20 yrs. I was feeling not well at all, no energy, pale, tired all the time always cold!. He ran a series of blood work, here was enemic, ferritin levels low,etc. Then had to do a series of blood infusions, what difference. I had issues with this for several years, had further testing done to check if was loosing blood, none of the test showed anything! Kept doing my blood work getting infusions, eventually things were getting better and needed less infusions. Kept following up with Dr. Callahan every 6 months, I think since 2020 my blood has been good, numbers good , last year he said let's try a year, gave me scripts for my blood work as usual as precaution just seen him on the 11th of June, number still good was going to discharge me but asked if we could do 1 more year just for my comfort! Still have my regular blood work routine and will see him again in [Date] Dr. Callahan is very compassionate, has a great beside manner, caring, easy to talk to and goes above and beyond to get to the source of the problem. I am so thankful for Dr. Kevin Callahan and I know I can always count on him to get be feeling better! He is the best and always highly recommend him! !

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

I love all my Cooper doctors I will never leave Cooper for no other doctors they're the best Dr Callahan is a good doctor I'm proud and I'm very happy with my Cooper doctors I think you are so much for everything that you have done for me and help me with and got me back to my strength in my life again good doctors thank you so much I remember having my twins at Cooper and the doctor said I don't they only had three days to live my babies are here today will be 50 years old and November thanks to Cooper one way to pound and 15 oz and one way to pound and 12 oz what a blessing thank you Cooper I will refer anyone to Cooper this Cooper is Cooper my doctor God bless you all continue being strong and helping others like you help me thank you Cooper I love you
