I love everyone who works here. You can tell it’s a great working environment. Dr DeMera is not only a great doctor, but is funny and not intimidating when asking questions. My allergies are night and day from getting shots the last 4years. (I’m highly allergic to almost everything but food). I wholeheartedly recommend them for you or your children’s allergy needs.

DeMera Allergy, Asthma, and Immunology Center is by far the most professional, courteous, and caring office I’ve been to in the area. Wonderful care.

Dr. DeMera is pleasant and a brain when you need help with anything in his field and can usually know what you need even if it’s not in his field and knows who to refer you to. His ENT specialist Dr. Sherman is also a brain and amazing.The staff is always polite, organized, professional, and wonderful to work with. He also works in two locations, Fresno and Visalia making it easier for traveling to him from out of town.

Dr. Sherman, top level anywhere as far as I can tell, genial, highly expert and one of those people who are lucky enough to be deep into what they are doing to the point of fine artistry. His Dx/Rx made my problem of chronic ear infections after living in tropics markedly better with first visit, as well as taking time to explain processes involved with healing and the probable course of the illness. My highest recommendation.

Dr. Demera and Dr. Sherman are caring ❤ Dr's and really seem to take an interest in their patients. When you are dealing with an issue they follow up with you in a timely manner to see how new treatment is going and if not going well, they try out something new and continue to check back until they get it right.

I personally had seen Dr. Demera for years and plan to go back in a few months. Out of two options from Valley Children’s hospital for my sons asthma I didn’t even let them finish their recommendation. I cut them off and let them know I’d be taking my son to Dr. DeMera. I had received excellent care in the previous years and yesterday’s visit made me feel confident that my sons health is in the best care.

The office staff was friendly and efficient. To my surprise I was called to the back within 5 minutes, the doctor was in right after that. We went over my history. Tests were done, results were good. The doctor actually listened to my concerns and has requested other tests to be done.Overall experience was a good one for being a new patient.

I found DeMera Allergy after my allergist retired. I have been so impressed with this office. Everyone is polite and professional. I have received top notch care since I found Dr. DeMera. I highly recommend this office.

All the nurses and staff are very nice and professional. The nurses that give my daughter allergy shots always talk to her and make sure she has a water to drink after her shots 😁 They are very welcoming as well. Dr DeMera is by far the best allergies my daughter had so far. He takes time to explain everything. Highly recommend this to anyone that needs a good allergist. Thank you all

I worked for Dr. DeMera for two years and he was honestly the best doctor I have ever worked for. Not only is he a great boss but he genuinely cares about every patient he sees. He will go above and beyond to get to the bottom of the problem and if he can’t figure it out he’ll refer you out to someone better specialized for your specific diagnosis. The staff is all warm and welcoming, and will try their hardest to make sure you have the best care possible. In my time at DeMera Allergy I was also seen as a patient for allergies, eosinophilic esophagitis and ear issues. I highly recommend seeing Dr. DeMera and Dr. Sherman; they are both amazing doctors with great passion for their specialties.
