Our Patient Testimonials

“My experience at the clinic has been very positive. Front desk staff is attentive, the nurses are professional, Dr. Engler was precise with his evaluation and billing was accurate. Even with a constant wave of patients coming through the doors the staff provides professional and courteous service. Would definitely recommend to friends and family”

I've been a patient at The Allergy and Asthma Clinic for over 12 years, and I can't speak highly enough of the care I've received. Growing up with severe pollen allergies, I’ve been on and off allergy shots for years, and this clinic has truly been a lifesaver for me. Read More

I had an amazing experience at this clinic. Dr. Engler and the staff were all extremely welcoming, warm, and thorough in their various lanes of work from the front desk to billing to the assistants to Dr. Engler himself. Read More

Hands down the best place to go for Allergies and Asthma. The staff is incredibly kind and caring and so professional and helpful. I've been going here for over 30 years and they have gone out of their way countless times to make sure that I was well-cared-for. Read More

Had 2 visits here and the recommendations worked to drastically reduce my seasonal allergies. The staff is friendly aNR professional and the office is very clean. They go the extra mile to prevent germ and virus spread.

-David G

Love all the help from Dr. Engler + all the friendly staff! It’s a pleasure receiving care here, and these shots have improved my allergies significantly. It can be 30 minutes wait time to receive your shots during peak hours though, so plan accordingly! :)

-Linda Q

Dr. Engler is great and his staff, both medical and administrative, are wonderful. Dr. Engler is competent, caring, and listens better than any doctor I've ever had, constantly and patiently asking if I have any more questions. Read More

First and foremost let me start by saying that these people did one hell of a job figuring out my sinus problems. When I first arrived there, I explained what was going on with me having excessive inflammation in the sinus. Read More

“Wow! I'm going to age myself by saying that I haven't received customer care like this in decades! Finally a doctor and staff that are consistently welcoming and caring across the board.”

-Tee J

"I highly recommend coming here to see Dr. Andrew Engler (and shout-out to nurse Jessica) for allergies for experienced and high-quality care. This is one of the best-run doctor's office / clinic I've ever gone to and the people are so nice, patient, helpful (nurses, front desk, doctor). The allergy test was comprehensive (~80 allergens) and aftercare was great. They also had billing come talk to me to make sure I understood the pricing since it was a long-term treatment plan. Great experience."

First and foremost let me start by saying that these people did one hell of a job figuring out my sinus problems. When I first arrived there, I explained what was going on with me having excessive inflammation in the sinus…after they tested me, I found out that I was being exposed to dust mites which gave me a strong reaction. I followed the doctors guides lines in terms of cleaning my room and ever since, my sinus inflammation went away for good and now I have a healthy sinus. Thank you for everything.

Dr. Engler is great and his staff, both medical and administrative, are wonderful. Dr. Engler is competent, caring, and listens better than any doctor I’ve ever had, constantly and patiently asking if I have any more questions. The staff is great. The nurses are very friendly and helpful. The desk staff is the same. I have been going here over a year and have always received caring and competent treatment. I highly recommend them.

Hands down the best place to go for Allergies and Asthma. The staff is incredibly kind and caring and so professional and helpful. I’ve been going here for over 30 years and they have gone out of their way countless times to make sure that I was well-cared-for. The nurses are excellent and always make sure to ask how my family is doing not to mention that they give the most painless allergy shots around. They remember little details about me and always make sure to give me a lollipop for my son, even when he’s not with me. Brooke is a great diagnostician and listener and each time I have an appointment with her, I always leave feeling better. The same is true for Dr. Engler.

My 10 year old son also has allergies and asthma and the staff makes sure that he feels well taken care of and comfortable, despite his having Autism and ADHD. He actually looks forward to going there with me, whether it be for my allergy shots or even when he needed allergy skin testing. When you’re a patient at the Allergy and Asthma clinic, you are treated as if you are the only patient they have, even when the waiting room is full. Dr. Engler has hired truly excellent staff, from the front desk people to the nurses and medical assistants. If you have allergies and/or asthma and you live on the Peninsula or even in the city, I highly recommend that you visit the Allergy and Asthma Clinic. They are truly amazing and will make you feel so much better.

I had an amazing experience at this clinic. Dr. Engler and the staff were all extremely welcoming, warm, and thorough in their various lanes of work from the front desk to billing to the assistants to Dr. Engler himself.
One thing I wish I knew before coming in was that the food test covers 80 allergens, and the environmental test covers 80 allergens meaning if you want to do both you need to come two separate days. This is kind of a hassle but definitely worth it since you’ll be tested for 160 allergens whereas most clinics only test 80 total.
Through the tests I figured out what I was allergic to and was advised to use an over the counter medication which has drastically helped and eliminated the symptoms I was experiencing. Dr. Engler also covered all the things I needed to do to reduce my symptoms via my lifestyle which was super helpful with my symptom reduction as well. I’d highly recommend this clinic! Insurance covered the tests and visits. (I have anthem blue cross)

From the moment you walk in, you’re treated like family. The staff is incredibly kind, caring, and genuinely invested in your well-being. I have never had a negative experience with anyone here; everyone is consistently friendly and supportive.
Dr. Engler is exceptional! He has a remarkable ability to quickly and effectively address any situation. His expertise and compassionate approach have made a significant difference in managing my allergies.
If you’re struggling with allergies or asthma, this is the place to go. I wholeheartedly recommend The Allergy and Asthma Clinic to anyone seeking top-notch care.
