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.

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

I had a first time visit with Dr. Casselman. He was very knowledgeable and had a lot of ideas and insite for my condition. Nice guy.

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 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.

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.

Jul 28, 2022

Dr Casselman and the staff are the best!!!

Jul 27, 2022

Neither the nurse or the doctor asked much about my medical history, just went off of the medications I'm taking. The doctor provided very detailed explanation of plan of care and why he is making those recommendations. I have a unique medical history and would have been nice if that was taken into consideration when making care plan instead of just focusing on present symptoms.

Jul 13, 2022

Dr. Casselman is the best allergy doctor I've ever had! He takes his time and listens to my concerns and has found the perfect regiment of medications to alleviate my symptoms. As long as this doctor is in Richmond, I will never see another allergy doctor. I am grateful for his care!

Jul 13, 2022

I am thankful to have a Dr that really cares and is very thorough.

Jul 6, 2022

The people in this office is really nice

Jul 6, 2022

Dr. Casselman is thorough, knowledgeable, and a great listener. He gets to know his allergy/asthma patients individually resulting in fewer symptoms. He is very personable and sincerely cares about making his patients healthier! Lately it seems, the outstanding doctors are leaving Reid for better options. Hopefully Dr. Casselman remains with Reid in Richmond for a long time. I'd consider following him to other Health agencies.

Jun 30, 2022
