Wonderful ‘bedside’ manner. Explained everything, answered my questions, and put me at complete ease.

He will be sorely missed!

My only complaint would be that I had spent 3 weeks trying to get a message through that my prescription needed renewed. When it finally was, I was not notified that it had been done. Hy-Vee pharmacy did not notify me either.

Thank you for not shaming me about my A1C and helping me to create a plan to address it. Thank you for your patience and understanding about the multiple health concerns that impact one another.

Everyone at this clinic is fabulous.

Even though I have been regularly coming to the Diabetic Health Clinic for years, I always am encouraged by Joy Schrader - her advice and knowledge makes my application of it do-able. I trust her.

Discussed continuing my normal prescription. NOT generic. She agreed to refill. Dr prescribed generic anyway to my pharmacy. Had been on previous meds 2 years.

The best Diabetic DR I'v ever seen.

May 4, 2026
You can't describe "caring" more than thru her!

May 4, 2026
I like her a lot and then she takes good care of me. I’ve never had my cruises and stuff better like I said it isn’t about her. I like her very very much but the rest of your place is so hard to get any information. Find anything or do anything so until I talk to her in person I just avoid you guys.

Dr. Dy is an excellent doctor that cares about her patients.

Apr 28, 2026
My provider can't be beat. He has all the qualities of what a provider should be like.Used to be all providers felt the same way about patient care. Many now look at it as a professional job with pay and their heart isn't in the type of patient care thatused to be found. Dr. Khoo is one of the few exceptions to the rule. He shows, care, compassion, concern and wants to make things better for his patients.

She is very professional and caring.

Extraordinary care!

Dr Johnson is an awesome doctor! He listens to any concerns/questions and explains things very well! I am so glad I stuck my ground & said I wanted to wait until I could get into him as a new patient years ago, even though I knew I could have gotten in to a different provider sooner. He will be greatly missed! I wish him a very happy and healthy retirement!

Apr 27, 2026
He is frank and truthful

Will miss him as he retires. he is a good man, as said before wonderful person

Apr 23, 2026
Dr. Khoo is amazing and thorough. He addressed every concern I had and let me know what to expect over the next several months. He made changes to my care that were helpful and would make getting necessary medications more convenient. I really value the information I receive when I attend my office visits with Dr Khoo.

I've been with Dr Johnson for 15 years. That's when I was diagnosed with Type 2 diabetes and I wasn't aware of that. Dr Johnson informed me about diabetes and how to deal with it. Dr Johnson is great.

Apr 21, 2026
She’s nice, but lumped me in with other patients with similar issues. Could not fathom I might be a different case/diagnosis with the same issue others have.

Apr 20, 2026
Very kind and caring, DID NOT make me feel like just another patient. Explanations were clear and always asking if I understand or have any further questions.

Apr 20, 2026
Her accent can be hard to follow as she is not from the USA and she talks really fast.

Apr 17, 2026
Impressed with her and her knowledge gave me a lot of insight on how to care for my diabetes. Gave me ideas.

Apr 17, 2026
