Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Non compliant with regulatory guidelines
This provider’s office never has appointments within regulatory guidelines and when you come in for your appointments, they do not see you on time. This office is in violation of health and safety codes that I will be reporting to the state, as this provider should not be overbooking if they cannot provide timely patient care.

Ignorant
The doctor is disrespectful. I came because my doctor referred me to see an allergist from a bad allergic reaction. I have been to the ER because I struggled to breathe with hives on my body and blisters on my fingers and my doctor and the ER told me to see an allergist. Now it has been a month and the blisters have gone away but I still struggle to breathe when I sleep and my skin keeps breaking out. I finally went to see an allergist. When I try to speak to the allergist he does not listen. He talks over me and tells me it is just allergies and that I never had an allergic reaction. I said I don’t get bad allergies. It is not common for me to break out in hives and have breathing issues. The doctor said I never had blisters and that it was probably just bed bugs and dust mites. My grandmother has bad allergies, especially dust, so we make sure to keep the house clean. When I was trying to show him a picture he snatched my phone out of my hand and talked to me like I was dumb.

Don’t recommend
This practice is focused on getting a high volume of patients through and not on patient centered care. I don’t care for the doctors bedside manner or the amount of time he spent with patient. The policies of the office are a barrier (appt./shot scheduling, hours, notes for work/school). On multiple times the staff is arriving and unlocking the front door right at 8 when I had an 8am scheduled appointment. The nurses that give shots are nice and good but that was the only positive about this practice.

Dr. Offenberger has been treating my allergies for about 18 months. It took about 9 months to get things under control but since then, I've been symptom free. His competent office staff administers the monthly allergy injections and Dr. Offenberger personally reviews my case and progress every six months. It's good teamwork and based on the Doctor's office procedures, there's never any waiting or delay.
