Dr. Casselman is amazing! We absolutely love him. He makes sure we understand everything. Takes time to explain stuff to my daughter, he is just simply amazing.

Mar 28, 2024

I like to tease Dr. Casselman because he reminds me of my own kids. He is a very personable man and also very knowledgeable. I appreciate his good personality.

great service from all employees, professional

Feb 22, 2024

Dr Casselman is a great doctor, I hope I can keep going to him. It's about the insurance that worries me. xxx

Feb 21, 2024

I'm being referred to an endocrinologist. It could take months to solve my problem.

Feb 19, 2024

Dr. Casselman has been extremely helpful with my boys and their food allergies. He has gone over and beyond to help my son, xxx, with trying to get into the military and his food allergy being somewhat of a roadblock. He has been very communicative with xxx and even wrote a letter in support of xxx to share with his recruiter to try to help him be able to join. We appreciate his time and effort very much!

Feb 15, 2024

Dr. Casselman is extremely knowledgeable about my genetic, rare immunodeficiency. I was very pleasantly surprised at his familiarity with my long and complicated medical history. The questions he asked, and the referral he made, was very en pointe. As an educated person who is self employed and has a primary immune deficiency and several autoimmune disorders, it is very rare to find a provider who invests the time and energy needed for me to continue to be productive, be concerned for my quality of life, and talk to me versus at me. I very much appreciate this provider and his team, and feel very comfortable placing my healthcare in his hands.

Feb 7, 2024

Everyone was very nice and friendly

Jan 31, 2024

The front office was excellent- great service and very kind. Dr. was great, too!

Jan 30, 2024

I felt good and completely satisfied.

Jan 24, 2024

Quick and didn't talk over my head, was easy to understand.

Jan 23, 2024

Dr Casselman and is his staff are very thorough and are very courteous and caring.

Jan 23, 2024

I have had what I was told by another doctor was allergies and sinus issues for thirty or more years. Through those 30+ years I was given weekly shots, daily meds, nasal spray, surgery, and 3-4 times a year, antibiotics. When I switched doctors, Dr. Casselman diagnosed me with LPR. After just a few days of medication for LPR my symptoms disappeared. I have had no problems for the six months since he began treating me. I am very pleased. xxx

Jan 22, 2024

Everyone was very professional and very knowledgeable. His assistant was very knowledgeable and nice.

Jan 16, 2024

Was amazed at the speed of things. My appointment was an entire hour long but they did so much in that hour and at the end of the day I feel 100% better with my new treatment! Hardly any of that hour was I just waiting to be seen! They were all very nice and helpful!

Jan 10, 2024

Very courteous and professional.

Jan 3, 2024

Really nice. Bounced back and forth, made the appt take longer than what it probably should. Did talk to me in a condescending tone at one point after I asked a question.

Dec 28, 2023

I appreciate Dr. Casselman's and his staff's compassion and thoroughness with xxx's care. We have seen huge improvements in his allergy symptoms. Dr. Casselman and his practice deserve all the credit for that.

Dec 27, 2023

Making progress in trying new things to get asthma under control and prevent/reduce allergies

Dec 27, 2023

Very pleased!

Dec 27, 2023

There is no preventable intervention for my condition. Dr Casselman was very thorough and professional.

Dec 20, 2023

Dr. Casselman sat down with both me and my husband to fully explain what was going on with what he was looking for. Yes I was stubborn at times and I am so happy that I finally listened to him and did the needed tests to discover my issue. He has been patient and kind through this past year with me. I'm looking forward to my continued relationship patient/Doctor to help guide me through any allergy procedure. I would definitely recommend him to anyone!

Dec 14, 2023

People were professional and friendly

Dec 13, 2023

I feel that Dr. Casselman has helped control my asthma and allergies very well.

Dec 7, 2023

The nurses and doctor were both friendly and thorough. I feel like my concerns were addressed and that a good plan for my medical needs were put into place.

Dec 6, 2023

Thank you!

Dec 6, 2023

The allergy clinic and all of the staff are great!

Dec 5, 2023

Dr Casselman and his staff are amazing. They are always helpful with any questions and will call me if there is any issues with getting my inhalers or shots.

Dec 5, 2023

Doctor and all employee's were very nice and very knowledgeable.

Nov 21, 2023

Dr. Casselman is the best allergist/asthma, copd specialist! He knows each patient's history and prescribes the needed appropriate treatment! Please do whatever is in Reid's powers to keep Dr. Casselman in your system. It seems like you loose the great ones. I would follow Dr Casselman's practice if he left. Reward him, thank him!

Nov 20, 2023

Very thorough and friendly doctor and nurse. Staff also friendly and helpful. Thanks!

Nov 16, 2023

He took pictures to show another Dr. He called me a few hours later to tell me what the other Dr said. They both agreed I need a biopsy. He was pretty insistent that I get the biopsy. I called immediately and now have an appointment in about a week. Dr Casselman has prescribed medication that has almost gotten rid of my inch problem. I was miserable before I met him. I had been seen by multiple Dr's. with little help. So happy my son suggested I see Dr. Casselman. Wish I had been told about him a lot sooner. I've been miserable for over 30 years.

Nov 8, 2023

Dr. Casselman is hands down one of the best providers around. Every visit with him for myself or my family, he has consistently amazed me with not only his approach to the issue being discussed, but also with his knowledge of our medical history and his dedicated approach to get the best result possible. I will continue to recommend him to family and friends!

Nov 7, 2023

Mindy was very friendly & helpful! Dr. Casselman explained everything well. He listened carefully & made sure I understood the plan. I was very happy with my visit!

Nov 6, 2023

It was a very good process. He listened well and made sure he understood everything before giving his recommendation of what needed to be done.

Oct 31, 2023

The Dr. and staff were very kind and attentive. Will go back.

Oct 30, 2023

I finally find my favorite nurse from the urologists office. Tammy is one of the greatest, she told me everything I needed and Dr Casselman explained everything and gave some good suggestions. Sure makes an appointment go better when the staff are friendly even the receptionist was great!

Oct 25, 2023

Excellent - please share! xxx

Oct 25, 2023

Every one was nice.

Oct 24, 2023

Everybody in this clinic has been very kind, generous of their time and excellent in providing care. Thank you!

Oct 19, 2023

Dr.Casselman is a good doctor he knows his stuff

Oct 9, 2023

Dr. Casselman and his team are top notch, always giving me the best care. They respond in a timely manner. Dr. Casselman always takes the time to explain the "why" to me, which is very important to my understanding of my treatment. He's always thorough. I feel like I'm in good hands with my asthma and allergy needs!

Oct 9, 2023

Very pleasant

Sep 26, 2023

Best Doctor out there!

Sep 26, 2023

This place is simply awesome and amazing ??

Sep 18, 2023

It was a great experience. They took the time to listen to what I had to say and addressed each of my concerns individually. It was refreshing to actually have a doctor that took time

Sep 13, 2023

I waited 40 minutes beyond my appointment time before seeing the doctor. The practice seemed to be booking too many patients. Guess that's why we're called patients since we're expected to be patiently waiting to be treated.

Sep 13, 2023

My Medical Assistant Elizabeth was amazing and so caring!!

Sep 12, 2023

I am happy with the care I receive from this provider.

Sep 7, 2023

Fast, convenient, efficient, and friendly. Can't ask for much else.

Sep 6, 2023

When I have been at my lowest point with an asthma exacerbation, Dr Casselman knows exactly what regimen will help me get back on track. Dr Casselman is always up on the lastest asthma treatments which has been quite beneficial for me. He's been a real lifesaver!

Aug 30, 2023

The nurse was very polite she explained what was going to be done and how it was going to be done and the dr explained to me every thing I need to know he explained my options for treatment and he said I could call if I have more questions sometimes I hear what they are saying and understand it but then I am forget full so I glad I can call back if I have more questions

Aug 30, 2023

Thanks for caring!

Aug 29, 2023

I like that he didn't do unnecessary things. I am very happy with the direction he is going with my health!!

Aug 29, 2023

I appreciate that Dr Casselman is a thinking, intelligent man.

Aug 24, 2023

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

They were knowledgeable and took me seriously. I really appreciate it.

Jun 27, 2023

We love Dr. Casselman and his staff! They always treat us wonderfully!

Jun 22, 2023

Dr. Casselman and team (Tammy especially) are amazing and handled our children's needs with exemplary care and attention to detail.

Jun 20, 2023

Dr Casselman and his staff are excellent! Tammy is my favorite! They are caring, timely, and really know about the patients!

Jun 13, 2023

I always enjoy visiting Dr. Casselman and his staff they are always very friendly and I don't feel anxious when coming to an appointment. I've recommended Dr. Casselman to several people.

Jun 5, 2023

They were friendly and sincere. They listened and treated me in a very professional manner.

May 30, 2023

May 30, 2023

Dr. Casselman ans the nurses are great

May 24, 2023

Mindy, Susie, Aiza, and Dr. Cassleman where awesome.

May 23, 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.

May 18, 2023

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

May 9, 2023

Would highly recommend. Everyone was very courteous and extremely helpful.

May 8, 2023

Provider was very condescending, talked over my wife and I, and difficult to talk to.

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
