Good experience.

National Jewish Health PatientSeptember, 2021
*Dr. Lanser is a wonderful dr. and he listens and provides wonderful feedback. I can not say enough wonderful things about him and the care he provides.

National Jewish Health PatientJune, 2021
I have told multiple people about how great my experience with Dr Lanser at National Jewish was. While it was difficult to have my child diagnosed with an allergy, I was so glad to have it happen at National Jewish. Dr. Lanser spent so much time explaining my child's condition, answering questions and providing support. I was thoroughly impressed by the care that my child received. This was the best, most thorough medical appointment that I have ever attended. Dr. Lanser is an exemplary clinician and I am very glad that my daughter is under his care.

National Jewish Health PatientJune, 2021
Dr. Lanser always takes the time to listen and respond to all the questions I have. I never feel like he's trying to rush out of the room and on to the next person.

National Jewish Health PatientApril, 2021
This was the absolute worst care and overall experience I have ever endured. Dr. Lanser was extremely late, he walked into the room and immediately sat down and laughed at my husband and I. He told us how the previous appointments, time, and care we had been showing our son for the last 6 months was wrong and could be chalked up to [PHI]. He did not once look at our son (our son was fully clothed the entire time), and he spoke in circles about the history I took the time to write out for him. [PHI].

National Jewish Health PatientApril, 2021
Dr. Lanser has been incredible. He is up to date with the latest research in his field, and I have confidence in his ability to assimilate new information coming out. I also love that he is a hopeful person. He thinks not just as a clinician but also like a scientist. This is one of the things I love about him. He is also very caring to my son and takes time to show that. He has been very patient and understanding with my questions, even before my son came into his care as his patient.

National Jewish Health PatientApril, 2021

National Jewish Health PatientApril, 2021
