Doctor Casselman and staff were professorial and attentive during my appointment.

Aug 23, 2023

Dr. Casselman is great. I really like him.

Aug 21, 2023

Dr. Casselman and his nurse was phenomenal. I felt heard and my questions were answered.

Aug 17, 2023

I'm very, very happy that I changed doctors. I feel that Dr. Casselman really knows what he is doing and I've come to trust what he has to say and his care over me. He's kind of straight to the point, and not too chatty, but he's gets my diagnoses right every single time and has my respect. Tammy is a lovely and super kind person!

Aug 10, 2023

Wonderful doctor that i totally trust.

Aug 9, 2023

Waiting for my ellargy test results. Let you know next visit

Aug 9, 2023

Excellent doctor and staff. I left informed and confident in my health plans.

Aug 2, 2023

My doctor in the past constantly brushed me off and never gave me a real diagnosis. Here I felt like I was finally taken seriously by a doctor who listened to me and gave me a diagnosis that made since and was willing to talk me through what it was and treat me for it. This was an amazing experience and I would recommend here to anyone.

Aug 2, 2023

Excellent doctor!

Aug 1, 2023

You should clarify a few of your questions. I don't expect the same questions for a specialist as I do for a Healthcare provider.

Jul 31, 2023

The staff, nurse and doctor were all wonderful.

Jul 25, 2023

Very pleased with the visit today. Explanation on treatment was clear and any questions I asked were answered clearly. I am encouraged by the visit today.

Jul 19, 2023

Great doctor

Jul 19, 2023

Everyone was nice. Dr. Casselman was very personable and pin pointed my problem right away, which led to me NOT having to have allergy testing done.

Jul 19, 2023

Very personable. First time seeing this dr. I'm going to recommend him to my daughter.

Jul 19, 2023

Staff and Dr. Casselman were friendly, interacted well with my children.

Jul 18, 2023

I really appreciate Dr Casselman, without him I would have never got well & I was so sick. I cannot say enough good things about his care. Again I do appreciate the fact he is Reid Health.

Jul 17, 2023

The Dr. Is really nice and knows what he's doing. Thank you!

Jul 13, 2023

Awesome service

Jul 12, 2023

I probably wouldn't be here without the expert care from Dr. Casselman and his staff!

Jul 12, 2023

The doc told me how scratch and blood tests wouldn't really be beneficial in my case, gave me some good science and info on foods to avoid graphed in separate phases of IBD to give me a more constructive way of seeing how to live with colitis, and referred me to gastro specialists in Indianapolis, though I plan to stick with Dr. Rofail for scopes and Colonoscopies. I feel adding another gastro will give me a more aggressive approach to my ulcerative colitis, which I believe I need.

Jul 12, 2023

Fast, efficient check in and check out. Minimal wait time.

Jul 11, 2023

Dr Casselman is a wonderful doctor. He listens, he cares.

Jul 10, 2023

Great visit with the doctor. Terrible experience with post-visit care and communication about lab work. Highly disappointed that the nurse referred me to get lab work done at a lab that had been closed for over 8 years. I spent hours of time driving to another town only to find out that lab has been closed for years. Then, went to another lab facility only to find out that the lab work had not been completely submitted by the nurse. For example, not all of the requested lab work had been submitted AND for the work that was submitted, the nurse had incomplete comments about how to collect the samples for proper testing. The lab tech spent almost an hour on the phone with the nurse to try and correct the errors-which were not corrected in a timely manner and caused me to have to return on another day to attempt in getting the lab work completed. This entire fiasco could have been prevented by 1) an informed nurse giving proper information and 2) a nurse who had sent a complete lab work request.

Jun 27, 2023

Listened and referred to another Dr

Jun 27, 2023

Everyone was so gracious..... The doctor actually took time to talk to me... It was wonderful...

May 18, 2023

Dr. Casselman is great. He listens and I feel 100% confident with him. Suggestion...I would love to be able to schedule my monthly allergy shots via MyChart.

Dr. Casselman has changed the quality of my life. I fully trust him with my medical care.

May 4, 2023

Dr Casselman and his nurse were great.

May 3, 2023

The staff and the doctor was awesome.

May 2, 2023

Everybody was friendly and helpful. I was informed about each step, and what was next.

May 2, 2023

Dr Casselman has been so helpful to me.

May 1, 2023

I couldn't speak without being cut off. He dismissed all my child's previous allergies because it wasn't his own diagnosis and even claimed them as flukes. My child also had to have another blood draw unnecessarily as he had the blood draw from his normal doctor in preparation for the visit. It was a waste of our time to come the hour.

May 1, 2023

Very professional and personable. Great experience.

May 1, 2023

Well satisfied

Apr 26, 2023

Dr Casselman was such a blessing to me today. I was at the end of my rope today when I saw him and he has given me hope in a treatment that will get me back to my old self. So knowledgeable and very confident in his work that he can fix my problem with my skin. Thank you!

Apr 25, 2023

Would be nice if it didn't take so long to get in as a new patient.

Apr 25, 2023

The only downfall about my visit was I stopped my meds like told to and he still couldn't do the allergy test gave me a paper to have the blood test done instead but waiting to hear back once my insurance approves so I'm stuck in limbo for now

Apr 24, 2023

Dr Casselman was very patient and thorough with my childs care.

Apr 19, 2023

I was very pleased at how great the office was coordinated, I was in and out in less than an hour.

Apr 19, 2023

Dr Cassleman is very good and he helps to calm me down when I get overwhelmed by this sickness. It's very hard for me to understand why this had to happen to me. He explained how to keep my stress level down because that will also have effects with my condition. I think he is a great Dr and would recommend him to everyone I know. Thanks

Apr 19, 2023

They were all very nice explained the procedure . very nice

Apr 18, 2023

Wonderful staff & Dr.

Apr 17, 2023


Apr 12, 2023

I feel the doctor or nurse could have simply called to discuss the situation rather than us coming in to the office. This was a referral and after having the information for over a month regarding our reason for visiting, the visit was not needed. I missed work for a dr to tell me it was unlikely we would find the cause of an allergic reaction. It was a wasted trip and I missed work and pulled my child from their routine for what could have been said over the phone. It was frustrating to say the least.

Apr 6, 2023

Kiddos to this doctor. My goodness! He did his homework and Delved into my past history to make sure that I understood what my past tests had indicated about my present health. Love this doctor. I would highly recommend him to my friends and family members, because he cares.

Apr 6, 2023

Every one was polite and listened to me.

Apr 6, 2023

When I entered the room the nurse was very efficient. Everytime she enters nothing ,but smiles. A joy to be around. She should have a gem award.

Apr 3, 2023

His name is NOT xxx. It's just xxx. I'm started to feel like my son is being disrespected because you can't get his name right. I'm hoping this gets fixed asap.

Mar 30, 2023

Very helpful & wanting to help me with long time issue

Mar 28, 2023

Doctor was pomous and condescending. Office staff was nice. Wouldn't want to go there regularly.

Mar 28, 2023

Dr. Casselman and staff are amazing!!! Always seem timely, always thorough. I appreciate the quality care I recieve.

Mar 27, 2023

Doctor doesn't listen. He sees my son once a year yet over steps as if he knows him better than me. Arrogance is ignorance. I will be looking for a new provider.

Mar 23, 2023

Dr. Casselman was very nice, friendly, and asked lots of questions. I was very appreciative of that. He was also very honest and gave his input. The only negative is the long wait in the lobby and waiting room to be seen.

Mar 20, 2023

Dr. Casselman and his staff are outstanding. Dr. C is very knowledgeable and patient in explaining my options with treatment. All staff are personable and efficient.

Mar 16, 2023

Dr. Casselman is possibly the best physician I have ever had, and in whom I trust and respect completely. It's truly a blessing to be in his care. I feel the same way about all of his staff.

Mar 16, 2023

All staff, including MD, projected the most caring attitude!!!!!

Mar 15, 2023

As soon as I walked in the doors I was greeted so kindly! The ladies at the front desk were so sweet, & asked about my morning! Then the nurse came to get me from the waiting area and carried the same kindness with her! It just seemed as though everyone was full of the same positive loving energy! The doctor, made me feel comfortable, and I feel like he really wanted to help me. Which is a breath of fresh air. I appreciate everyone at the allergy office, from the moment I walked in, to the moment I left, everyone was great!

Mar 14, 2023

Dr Casselman is a great doctor. He is very knowledgeable and takes time to explain things and to listen to his patients.

Mar 13, 2023

My patient report showed the providers impressions from a physical exam- and none took place.

Mar 13, 2023

Dr. Casselman is very thorough and a great provider! He explained everything in detail and validated my concerns. Front office staff and clinical staff were great as well!

Mar 13, 2023

I like the way they make you feel like a person and not like a pay check. Super nice people. Thanks again

Mar 2, 2023

Everything was just great

Mar 1, 2023

Very nice and Professional Office, This Team is the Beat!!

Feb 28, 2023

Dr Casselman and his staff are the best!!

Feb 27, 2023

The office hasn't been able to get my records, they are at a company in Buffalo, supposedly, they haven't sent them, nor can they talk to anyone about them, I signed a waver in November to have them released, very frustrating for all involved.

Feb 27, 2023

Nurse Tammy and Dr. Casselman were very thorough, kind, and caring. I felt comfortable speaking with Dr. Casselman about my health, and I feel confident in the care and treatment plan he is providing me. Great first appointment and experience overall!

Feb 22, 2023

Feb 20, 2023

Very professional and courteous. Made me feel comfortable in asking questions. And got answers on my condition. I appreciate that whole heartedly.

Feb 20, 2023

I am very impressed with the office. I walked in and was greeted by friendly staff. They checked me in without difficulty. I was taken back prior to my appointment time. The nurse was very kind and listened attentively ! The physician was prompt, and ordered testing and medications for me. He made a plan and a back up plan. I am very thankful to have this office take care of me.

Feb 16, 2023

The provider was great, he answered my questions, listened to what I had to say. I think the person who did the actually allergy testing can be a little bit easier putting the marks on your back. It felt like a punch every time she did it.

Feb 15, 2023

Dr. dismissed concerns and family history. Went off all meds to complete allergy testing (which was miserable) only for them to not do the testing. Have my 15 year old a prescription med brochure and did not seem to listen. 10 minute appt. that we had to wait over two months for and was rushed. Would not recommend or return to.

Feb 15, 2023

For the first time in years, a Dr. Who loves his job of teaching his patients, and figuring out what is wrong an how to fix it. I would give them 100 if it was up there. Thanks so much for putting 100% in ur job, it makes the patient feel good inside and out and do the right things to make them selfs feel better! Y'all rock the bed side manner out !! Thanks so so much!!

Feb 14, 2023

Jan 9, 2023

The man was extremely nice he listened to my concerns the doctor took time to understand why I was concerned about certain things. He was extremely knowledgeable about what he was talking about and is even willing to help me further in more of my medical care. He was able to talk to me about my asthma treatment and treatment for my allergies. He even listened when I told him about my concerns about medication reactions with my depression. This is amazing doctor the man deserves a raise he was absolutely amazing and I will be going back to him in 2 weeks for some more treatment. He seemed really care about my concerns and how I was concerned about certain things due to my daily life. He listened about everything for my family history wise and when my aunt even had a question that she wanted me to ask he even answered that very well. He's an amazing doctor and if I ever need anything I know that I can contact his office. His nurse staff was amazing taking care to make sure I was comfortable and it was just all and all an amazing visit 10 out of 10 will recommend 100 out of 10 will go back

I will start them when drug store gets them ready, then can determine if helps. Prescribed two nasal sprays which I've always had trouble using nasal sprays, so not happy. But will try.

Nov 2, 2022

The entire experience was excellent from the moment we walked into the door. The office staff, nurse and Dr. Cassleman we're incredible. My 11 year old felt safe and loved. What could have been a terrifying experience actually turned out to be quit fun for him and that's 100 percent due to Dr. Cassleman and his staff. In fact, I've already given him shout-outs on my Facebook page. I'm grateful for this talent and knowledge within our community.

Oct 25, 2022

Sep 26, 2022

My first visit and I was extremely impressed with how he explained everything in detail to me, wasn't rushed at all, and left with a very comfortable game plan.
