I had an excellent experience in this office. The medical assistant is very helpful, friendly and prompt. Dr.Panzer took a long time with me, listened very carefully and developed a treatment plan with me. I felt heard. I called her days later after hours with an urgent question and she answered right away, talked to me for a long time, even though it was after 7 pm I am looking forward to my next appointment.

I was 18 min. late today due to unusual heavy traffic. Dr. Panzer peeked out of an exam room & told me to find another Dr. I can see how being late can throw sched. off, but there were times in her office when I patiently waiting after my appt. time. What was disturbing was the visible anger in Dr. Pazner's face, and lack of discretion to reprimand me in front of her staff & another patient. I've seen her be rude to staff but did not think she was capable of demeaning her patients. Not ok!
I feel I need to respond to this. This was the 4th time that you were late for your apt. I try to stay VERY MUCH on time- i feel that i cannot give you sufficient time when you come 20 mins late for a 30 mins apt. When you said it is hard for you to drive all the way to RMC , I suggested that maybe you find a different provider closer to you to facilitate your care. In regards to Erica , my MA we have worked together for 12 years and I appreciate her very much.

Dr. Panzer was a HUGE disappointment. Despite the claims on her website, I found her sadly lacking in attention to my "individual needs" and in basic communication: 1- She did not pay attention to my concerns. She appeared to have a "plan" in mind before she met me. 2- She prescribed medication without giving any info about how to use it, the duration of use or the reason for use 3- She refuses to communicate w/ patients outside of appts. I was only able to speak with her assistant
I am sorry you feel this way. I would like you to give us another chance. Pts actually can reach me 24 / 7 (!!!!) on my on call phone - the number is listed on my voice mail- i do not have an answering service. When patients tell Erica my assistant that they need to talk to me , i call back after hours, but not in between office visits, as I do not want to take time away from other patients. I always counsel on medication side effects. Maybe you let me know who you are and we try again.

Dr. Panzer is an amazing diagnostician. She believed in me when three other endocrinologists discounted me and told me that my thyroid problems were 'in my head'. I am a cancer survivor and owe my life to Dr. Panzer.
in Highlands Ranch, CO |
Dr. Panzer is very thorough & professional in her practice. She takes the time to ask questions & provides an in depth evaluation of her patients. I have a high level of faith in her expertise & analysis.

She listens well, I felt well taken care of . She is very compassionate and had a great treatment plan for me.

She is quite simply the best. I struggled for years with latent onset insulin resistant type 1 diabetes, doing everything the endocrinologists said. It wasn't until I found Dr. Panzer that I was able to get it under control. She is an expert, takes her time with you, keeps up on new developments and really LISTENS to your firsthand information. I trust her explicitly.
