Testimonials from patients of Dr. Gassner

from Marilyn in AZ March 18, 2024 for Lawrence P. Gassner, MD

When I moved to AZ 12 years ago my biggest concern was finding a new physician. But in no time my family found Dr Larry Gassner. I just want to give you a big shout out for being a terrific doctor. Your dedication and expertise is much appreciated. I feel confidant that I am getting the best care because of the dedicated, kind and excellent doctor that you are. I also feel that your staff,… See more

from Kathryn in AZ March 13, 2024 for Lawrence P. Gassner, MD

Dr. G. is a fantastic medical professional. In my experience working in the health care arena, it is not often that you find a physician whose ego does not get in the way. HIs does not. Dr. G. Listens - but most importantly really hears what I am saying. He is thoughtful in his explanations to my questions - and very detailed. I don't think there is any one moment that mattered more than… See more

The thing I value most about Dr. Gassner is his help in guiding me in making all kind of medical decisions.

The decisions he has helped with range from evaluating the risk vs reward profile of medical procedures, how to determine… See more

I have been a client of Dr. Gassner for a few years now. He has been remarkably supportive through my injuries and strange occurrences to this human body of mine. The staff is great also. He's a lovely doctor. So grateful to be a patient of this office.

from Kathleen in AZ February 12, 2024 for Lawrence P. Gassner, MD

My husband and I have been MDVIP patients of Dr. Larry Gassner for 14 years. We have been very pleased with the level of care we receive from Dr. Gassner and his staff. In October my husband had a respiratory infection that required several medications and phone consultations. Both Dr. Gassner and his staff were available to answer questions, call the pharmacy, and see him in person on the… See more

from Steven in AZ February 10, 2024 for Lawrence P. Gassner, MD

Dr. Lawrence Gassner has been the primary care physician for my wife and me for the past two years. During that time, he has shown an extraordinary amount of caring for us, being available to respond to our health issues at all times, even during personal vacations.

Dr. Larry Gassner is knowledgeable, compassionate, empathetic and younger than I am... all of which makes for a wonderful medical experience! 80, and still enjoying"the ride."

from Dan in AZ February 10, 2024 for Lawrence P. Gassner, MD

Being a relatively new patient to Dr. Gassner (one year), I truly appreciate his total approach to treating his patients. Not only is he professional as well as extremely knowledgeable, he truly makes you feel at ease and speaks to me in terms and examples that I comprehend.
Thanks so much.....

What will your life be like when you turn 100? A century ago the question seemed almost flippant, a needless consideration for most people, but today it's very real. The percentage of people living to 100 has grown almost 66 percent in the last 30 years, according to U.S. News and World Report… See more
