Patient Ratings

The Patient Rating score is an average of all responses to care provider related questions on our independent rating system, the Press Ganey Patient Satisfaction Survey. This survey is about the patient care experience and does not address crucial characteristics like medical decision-making, prescribing the best therapy, and patient outcomes.

Responses are measured on a scale of 1 to 5, with 5 being the best score. Learn more about our patient satisfaction survey.

Truly one of the best doctors I have ever been to.

National Jewish Health PatientAugust, 2018
The doctor was kind to my nervous little boy, but he tickled my son's belly to make him laugh...

Great experience, just wish I could get a lab results phone call back

National Jewish Health PatientNovember, 2017
We were thrilled with *Dr. Lanser. We heard of him on National public radio.

National Jewish Health PatientOctober, 2017
We love *Dr. Lanser! Excellent bedside manner, good listener, and explains things so they're easy to understand. He is caring and knows his stuff!

National Jewish Health PatientMay, 2017
whenever I see a doctor, s/he always has the courtesy to either ask my permission to include medical personnel not prior approved or at the very least informing me of any other medical personel that will be present during the visit. It would be common courtesy not to just send a 'fellow' into the office without prior introducing her. We came here to see Dr. Lanser. We did not come to see [Doctor]. Dr. Lander should have the courtesy to introduce [Doctor] to us!

*Dr. Lanser is the best doctor in Denver for my son....period.

National Jewish Health PatientSeptember, 2016
After interacting with Dr. Lanser, my husband and I immediately knew that he was someone we would like to continue working with. It is a struggle to find Docs that are smart, have empathy for us all, and can help us navigate through my son's health challenges. I liken it to finding a unicorn. Since meeting Dr. Lanser, we have scheduled a follow up appointment in order to get my son directly under his care.

National Jewish Health PatientSeptember, 2016
*Dr. Lancer and his staff speak directly to my daughter and this is very nice. They are incredible care providers.

National Jewish Health PatientAugust, 2016
Dr. Lanser changed our lives for the better. My son is healthy and his asthma and allergies are well managed. Dr. Lanser does what he can to continue to better and stay on top of my son's condition. My son was very sick before starting treatment with Dr. Lanser. Dr. Lanser cares about children and clearly has a passion for making a difference in their lives. My son plays competitive baseball and competitive hockey with no issues. I trust Dr. Lanser with my son's care completely!
