1. “If I spend enough time around the stuff I’m allergic to, I’ll build up resistance.” If this worked, I would put you in a pollen- or pet dander- filled chamber in my office rather than give you allergy shots! The problem is that desensitization to allergens only...

What Our Patients Are Saying About Us

Great experience and staff is wonderful!!

My son was referred to Dr.Trott-Gregorio by his pediatrician after struggling with regular allergy issues. We had to wait for a new patient appointment (about 1 1/2 months) but it was well worth the wait! Josie was our first point of contact and she is so personable, organized, & professional! Truly blown away by the extra mile she goes to make sure your scheduling experience is pleasant. Thank you!! Karen was our nurse and she had the tough task of explaining the allergy skin test to my 5 yr old son. He got a little scared and cried but she was patient and spoke in a calm and caring voice. The test was completely painless for him and because of her reassurance he was able to sit calmly while we waited to meet with our Doctor for his results. Dr. Trott-Gregorio has already been represented so well up to this point I was very eager to meet her! Let me say, she did not disappoint us. She took her time talking over my son’s results and making sure we understood along the way. What I loved so much about her approach was that she would speak directly to my son and not just me. She engaged with him and made him feel comfortable. I am grateful we will only need to return for a follow up a year from now but also bummed because the staff at Juniper Allergy put so many of our other doctors office experiences to shame! Thank you all for taking care of my little guy! Will be recommending to all of my friends and family.

Wow! How fortunate that I was referred to Dr. Amanda Trott-Gregorio. First off I’ll start by saying how welcoming Josie was once I arrived. Then Karen, the nurse, was extremely helpful in helping me understand the allergy testing process. Afterwards Dr. Trott-Gregorio took her time explaining the test results and answering all of my questions. I really appreciated her time and her thoroughness. I highly recommend Dr. Trott-Gregorio and her wonderful staff.

Dr Trott came very highly recommended by our sinus doctor. After today’s first visit we see why. Dr Trott and her entire staff are friendly, respectful, ask all the right questions, listened intently, and made us feel more like family than patients. We are recommending her to any and all friends needing quality professional care. Dr Trott tested for many allergies then carefully and fully explained her findings and recommendations. We are very pleased.

What Sets Our Allergists Apart?

Better Skin Testing

Advanced skin testing technologies now provide precise allergen identification, equipping healthcare professionals with detailed insights into a patient’s allergies. These enhanced methods improve the accuracy and reliability of tests, enabling the development of customized treatment plans that more effectively manage allergic conditions.

Better Immunotherapy Methods

Immunotherapy has also seen significant advancements, with new methods that increase the effectiveness and safety of allergy treatments. Innovations like sublingual immunotherapy and biologic therapies allow for more personalized and targeted approaches to allergy relief, reducing the likelihood of adverse reactions while optimizing therapeutic outcomes.

Cluster Immunotherapy

Cluster immunotherapy offers an efficient solution for patients with multiple sensitivities by administering several allergens simultaneously. This approach simplifies the treatment process, shortens the duration, and improves patient adherence, which is crucial for achieving better long-term results in managing complex allergic conditions.
