- Very pompous. Thinks he knows more then everyone else. Wants you in his drug studies. It is his way or the highway. Tells you what to do but does not answer questions.

- After decades of unresolved sinus infections, multiple surgeries, and years of antibiotics and oral steroids, no other doctor had been able to solve my repetitive allergy-triggered sinus pain and inflammation. Dr. Steven's novel antibiotic and steroid-free medication plan was the answer.
- I was very dissatisfied with Dr. Stevens. I spent 4 hours in his office on my first visit. I noticed he was very keen to suggest prescription drugs... Dr. Steven seemed annoyed and inpatient that I would be asking questions.

- top_results:} from the provided sources. I have determined that while some patients praise Dr. Gary Steven's innovative approach to treating complex cases, others have expressed significant frustration with his bedside manner, the perceived focus on drug studies/prescriptions, and administrative issues at his practice (the Allergy, Asthma & Sinus Center, located in Greenfield, WI, not Wauwatosa). Some sources also contain reports of unprofessional staff behavior or discrimination. Given the mixed nature of the feedback, it is important to review multiple platforms to get a balanced view of patient experiences.
Common complaints
- Reports of perceived high pressure to use prescription medications or participate in drug studies
- Allegations of poor communication, dismissiveness, or lack of patience with patient questions
- Complaints regarding office scheduling, administrative errors, and wait times
- Concerns regarding perceived lack of empathy or bedside manner
- Individual allegations of discriminatory treatment by staff
