I was skeptical but willing to give Quello a try. I started the program last spring, and I’ve been using the simple three-drops-under-the-tongue daily routine for about a year.
Before Quello, every spring and summer was marked by allergy misery—itchy eyes, an itchy mouth and throat, constant sneezing, avoiding grass and certain trees, and always having tissues nearby. I couldn’t go a day without my allergy medication without experiencing significant symptoms.
My experience has changed considerably over the past year. During my first season on Quello, I continued taking both Quello and my allergy medication. This spring is the first time I have gone through the season without needing my allergy medication at all.
I still occasionally experience mild symptoms, such as a slightly runny nose or a brief itchy throat, but they are temporary, usually lasting only a few minutes, and have never been severe enough for me to reach for my medication.
For me, this has been a significant improvement in my quality of life. I can spend more time outdoors and enjoy activities that I previously avoided because of my allergies. I’m encouraged by the progress I’ve experienced and look forward to seeing what the future brings.
Quello has made a meaningful difference for me.

Thanks so much for sharing your story! We're so glad that your results have improved your quality of life in such a profound way. Stories like yours are so great to hear. They help our team know the impact of our work as well as help other patients stick with it!
I was glad that there was an actual human, that did my assessment. He was professional, knowledgeable and kind.

Thanks for the feedback, we're very proud of the fact that we have a bunch of actual humans who care as a part of our team! Surprisingly, that can be hard to find with virtual health care these days.
I really loved the fact that I was able to complete and send in my test from home. It made things so much easier and gave me answers to my allergies that I'd been suffering from that had only gotten worse over time. Starting on Allergen Drops has already made a difference 2 years in. I've seen a drastic improvement in my symptoms already. There are still some high allergen days where I am a bit stuffy, but it's tolerable. Hopeful for the years ahead!

Quello is an amazing service
Quello is an amazing service. I had seen an allergist and the tests and treatment were so expensive. Quello does the test for free at home with a finger prick and just as accurate and almost as fast results. Stephanie helped me understand this a long term play but will be permanent and answered all my questions. My allergies are so bad I don’t mind taking the time to get my allergies fixed without drugs

Thanks for the feedback Susan. We expedited the mailing of your bottle as fast as we could and are sorry it left a few gap days for you, but we appreciate your commitment to taking the medication daily!
Everything has been so simple from the beginning! I feel really supported in how my allergies have been explained to me, and in getting started on healing them. I am looking forward to beginning my drops!

Convenient
Convenient. I am not 100% sold that this is going to make a big impact on my allergies/life and it's going to take a while to know but so far the experience has been great. Very good service provided by friendly staff.

It has been a wonderful experience so far! I had delayed allergy testing for years and been miserable living in Texas. the convenient at-home allergy test and online video appointment have made this so easy! I feel hopeful of finally overcoming my allergies again! my drops arrived in the mail today!

I had a really nice and helpful interview with my practitioner. She asked key questions and explained my results clearly. She also let me know what to expect moving forward. A little bit of tech glitch was handled by chat support!

Dear Stephanie, your amazing! Thank you so much for your help. We have set some accommodations at work to limit my exposure to allergens. Im so glad things turned out well and its getting better for me at work. They have also agreed to provide better fitting n95 masks since the ones they currently provide hurt my face and leave red marks on my cheeks. So all I've got to do is try out a few different kinds of masks to find one that fits. I am so grateful for your help. For so many years work has been stressful with all the allergens there & management didn't understand. But now that you advocated for me they are listening & willing to help. Its such a huge relief! I was struggling but now I'm feeling better and its all thanks to you! 💖❤🧡💛💚💙💜💖❤🧡💛💚💙💜💖❤🧡💛💚💙💜💖❤🧡💛💚💙💜💖
You & the awesome team at Quello are the best!!!!! Thank you all!!!

I am just over one year into my Quello treatment journey and so far it's been great. My allergy testing was even more complete than I could have imagined and the virtual appointment with the doctor was great. She took her time with me going over my test results and explaining how Quello works. It was a very thorough appointment and I really appreciated it so much, since I didn't know anything about this kind of treatment plan and protocol or how it works. They are always accessible, too, if I have questions or issues (which I haven't). It's been to easy to take the drops every day, and I haven't had any issues--even a little bit of relief already. I'm sticking with it because it's worth the effort to try--that's how horrible my seasonal allergies have been. Thank you for making this process so easy and professional! I have told lots of people about how great this is!
