Horrible experience recently with this doctor. I made an appointment for my son, showed up at the location given to me (Vernon Hills) and found that the location was boarded up....no sign, no tenants, no cars etc. I called to validate the mix up and they wouldn't tell me anything other than asking me to reschedule. Horrible customer experience and I will never reach out to this doctor or organization again.

Dr Guna helped diagnose my daughter after months of seeking help elsewhere. He sought out other experts in the field to help get us an answer, and finally treatment. We are so thankful to have found Dr. Guna.

I have never felt like I had to write a review before until now. We had a simply horrible experience with this doctor. After being 45 minutes late with no excuse as to why he spent 7 minutes with my child which included a few questions which he felt eliminated everything serious to a rectal exam which was completely mortifying and unwarranted. He then prescripted a drug that was completely inappropriate at the time( verified with another doctor) to her symptoms. NEVER go back again!

Guna walked into the room without barley speaking a word. he told my daughter, who he hadn't barely spoken to, made eye-contact with or even tried to make her comfortable, to pull down her pants, both underwear and her shorts, and to show him her butt as he would be performing a rectal exam. Please note, there was never a nurse in the room, or someone to comfort here. Instantly my daughter became hysterical. There is not enough room to tell me story here. But do not bring another child to him.

We have been nothing but pleased in our experiences with Dr. Guna. He listens to our concerns about our daughter's Crohn's disease, and we feel confident that we are getting the best care in Chicago. Office staff is helpful and responds quickly. We rarely have a wait in the office.

It seems that doctor Guna is first and only choice is Miralax to treat chronic pediatric constipation despite new (2015) data that Miralax should not be used long term not only pediatric but in adults as well because of toxicity FDA has opened a new research due to increasing complaints of side effects but he doesn't want to listen (he did not even know about it)and just give alternatives .he is very rigid and shows his temper, sometimes rude. it is Miralax or go find other doctor policy
