I have been treated by Dr. Fox for over five years, and have never experienced any of the deficiencies mentioned in these reviews. The front desk personnel welcome me to the office, and most of the time my wait is less than fifteen minutes. The assistants take my weight and other vitals in a professional manner, and the newer in-house blood lab has added a great convenience for me.

As for Dr. Fox, I believe he is knowledgeable, an excellent communicator, and takes the time to understand his patient and his issues. I hope others will use this facility, as findig an endocrinologist in greater Denver is tough.

Been going to Boulder Endocrinology for several years and just recently started seeing Sarah Waymire, NP. I couldn't be more pleased! Sarah is very innovative, up-beat, and resourceful. She has been very inspiring for me, because she emphasizes the positives and always has a game plan to work on the negatives! Claudia, Sarah's nurse, is exceptionally caring and friendly. Despite having to go to "the doctor", we do look forward to seeing Sarah and Claudia and the rest of the office staff at my visits.

I've been a patient at Boulder Endocrinology for years, my original Doctor left the practice but I decided stay with the practice in part due to location and because I've always had a positive experience there. This year I started seeing Sarah Waymire and she's been great, she's upbeat, knowledgeable, and kind. Changing providers has been seamless. Having an onsite lab has been so convenient, and all the staff are great.

I have been coming to Boulder Endo for a while now. I have been to many doctors offices over the years and this is by far the most organized and professional. The front staff always greats me with a smile and has always gone out of there way to make sure I get the best service available. My experience with NP Sarah Waymire and her Medical Assistant Claudia, has been second to none.

Even with the length of time between visits and the number of patients they always remember the little things about my life to prove that I am more than a number to them. Rather than following the script of what a "normal" patient should need, Sarah has an amazing drive to discover real treatments for your specific issues. I have had type 1 diabetes for 17 years and she is by far the best that I have seen and I have experienced amazing results with increased control of my blood sugar since I began seeing her.

Nurse Practitioner Sarah Waymire and Medical Assistant, Claudia are wonderful! Sarah has a great sense of humor and treats me thoughtfully; I feel able to be an active participant in my own health when interacting with her. Claudia is very calming and warm. I always look forward to seeing both of them. The administration staff of this office needs a little improvement and requires some patience to interact with, but the care providers make up for this lack.

Also the patient portal online makes it possible to communicate with my care provider directly, which is really easy, and prevents me from having to interface with the administration staff almost entirely. I highly recommend this clinic!

I started visiting Boulder Endocrinology again recently after having been a patient there almost a decade ago. Changes in my insurance made me switch to Kaiser, but now with Cigna, I am back and enjoying the services of Boulder Endocrinology. They are always friendly and efficient, easy to contact if I have questions, and have a good online portal, as well.

I currently see Dr. Sarah Waymire and am very happy with her so far. She is empathetic and knowledgeable, and I appreciate her willingness to work with me and my diabetes in a way that is most comfortable to me, instead of trying to force any particular care agenda. I would recommend her and Boulder Endo to any people with diabetes in the Boulder Valley area.

I've been a patient here for several years now, but the recent addition of Sarah Waymire, Nurse Practitioner, is the reason I'm still a patient. She is amazing! She really cares about how you are doing, and is all over new meds and new technology, and wants you to succeed so very much. She'll work with you to tweak your treatment to get the right mix of meds, tech, etc. If you're looking for somebody who truly cares about your diabetes treatment, go see Sarah!

I am a new resident to the area, and my primary physician recommended Dr. Rentschler at Boulder Endocrinology. She is fantastic! I have never waited at my appointment time, she never makes me feel rushed during my appointment. She spends times discussing my health situation, my treatment plan and medications. She is quick to address any concerns that I have, and fill prescriptions as needed.

My biggest concern when relocating to Colorado was leaving my doctors behind, and I am happy to say that Dr. Rentschler has become one of my all time favorites! The staff and lab facilities at Boulder Endocrinology are also equally excellent. I've now been a patient for over a year, and have never had a bad experience - on the contrary, I always look forward to a visit with Dr. Rentschler!

We relocated to Colorado in 2016, and knew we needed an excellent vet for our 12 year old lab. Legacy Veterinary Clinic was recommended by my brother, and we are happy that we took our "Trooper Boy" to Legacy Vet for an introduction.

I've had diabetes for 6 years now and just had my first appointment with Sarah Waymire. The best experience I've ever had. She was knowledgeable and spent +2 hours explaining how the medicines differ and what the game plan was for dealing with my diabetes. You could just tell Sarah was genuine and enjoyed what she does. This is a great place and great people to take care of you.

Mediocre to bad. I moved to Boulder in 2014 after discovering a few months earlier that I had Type 1 diabetes. So naturally I needed to get set up with a new endocrinologist. I scheduled an appointment, and the first thing I noticed upon arriving at the office and waiting in the waiting room was that several consecutive patients were having difficulty with the front desk staff, who were condescending and patronizing to each of them, and just seemed generally exasperated with patients.

I had an OK experience in the office with the doctor and the nurse, but I found that they never provided enough refills to the pharmacy to get me to my next appointment, and they discontinued one of my (badly needed) prescriptions without discussing it with me or explaining it to me. So, I dunno. Not very good.
