Patient Testimonials

“Great listener”

“Dr Cajigal is a great listener. She trusts her patients instead of treating them as if they are not the experts of their own bodies. I really appreciate that (many doctors do not have that quality). She also immediately treats the symptoms instead of waiting to see if things clear. I use her for my children and myself. We have never left her office feeling as if it was a waste of time.”

– Stephanie, August 2020

“Excellent doctor and amazing staff!”

– Janna H, August 2022

She listened and was very thorough in diagnosing my problems. “Had my first appointment with Dr. Cajigal. She’s wonderful. A different doctor had said there wasn’t much I could do for my allergies, except maybe move out of state. I was desperate and came to the doctor for help. She listened and was very thorough in diagnosing my problems. I’m not better yet but I’m very pleased with how this appointment went and I’m optimistic about my health!” – Rosana B, 2022
“Great listener and very caring.” – Stephanie, September 2022

“Great allergist!”

– Ann H, December 2018

“She is the best.”

– Stephen W, June 2020

“Really cared about how I was feeling”

“Dr. Cajigal was friendly, professional, and informative. She took the time to explain the tests and what was going on with my allergies. She is so knowledgeable and really cared about how I was feeling. I would highly recommend this practice if you suffer from allergies and asthma.”

– Sue D, July 2020

Dr. Cajigal is the kind of medical professional every doctor should emulate “I am happy to report that I am now hive-free and I hope that I never again have to endure this extreme discomfort. But if I do, I know exactly to whom I would turn: Dr. Cajigal at STL Family Allergy. I highly recommend her for all of your allergy/immunology needs. Her offices are spotlessly clean. Staff is friendly and helpful. And Dr. Cajigal is the kind of medical professional every doctor should emulate.” – Mary M, September 2022
So happy I found this office/doctor! “This office was AMAZING! I am so very impressed. I have never had more of a thorough doctor. The office staff was great too. I brought a newborn in and they all treated the situation of me having my baby there great. She made sure to lay everything out on the table of what could be the cause of my symptoms. She was so helpful. I also called because my shortness of breath were getting worse and the front desk and doctor made sure to handle it right away and get me over some medicine to help. I’m very impressed and so happy I found this office/doctor!” – Rachel M, 2022
Dr. Cajigal is the best. “Dr. Cajigal is the best. We’ve been seeing her for the last 4 years, having young children with allergies is scary. I have always felt listened to and not made to feel like any question is dumb.” – Amy D, 2022
