When I came she was trying to charge me a pending copay that was not taken care of last visit. When I made this appointment I wasn't aware of me having to do two copays, since it was a couple months ago and therefore I wasn't prepared. I really needed this appt today and the front desk lady Veronica was ready to CANCEL my appt, even though I told her I would be willing to pay today's copay and pay the other one in the days to follow on my payday. As I was really in need of today's appt, which I expressed multiple times! Luckily Joanna the other front desk miss saw my desperation and stepped in and made this a much easier process. I think it's important to honor policy and do your job but I was really looking for some compassion since I wasn't preprared financially for two copays. Thanks Joanna for showing compassion and my Dr. Christina was and always is amazing and makes me feel so comfortable when I come! Thank you guys overall! I appreciate it and will pay that pending copay asap. Five stars due to Johanna and Dr. Christina.

For now however the office experience was decent the ladies were friendly. As far as being efficient not so much at all, unsure of it's the office environment, lack of efficiency expectations but it's something. There is a lack of efficiency in customer service in public spheres but since we are locked in until open enrollment we will make the best of it.

I have been under the care of Dr. Unger since moving here in 2019. There are no words to describe…read morehow much this man, and his office staff, have changed my life. You see, there are those like myself whose predicament is one where a Dr's proficiency, and humanity is the key distinguishing factor between a life of suffering or a sustained quality of life- I am so blessed. I have a real support system. My review is for those who like myself are looking for help; I have never had any other doctor like Dr. Unger. He has far exceeded my expectations- and I live a quality life I never imagined. Thank you to his wife, and office manager, Lisa, and to Layla, they are amazing- the whole office!!!!!

I am writing this review, not as a patient of Dr. Unger but has a colleague in medicine. I am a…read morephysician as well who has been in medicine for 13 years. I have worked and been educated in 7 large institutions across the United States working with professors of all walks of life. I work as a consultant with Dr. Unger and interact with him regularly but in a different sub-specialty. I know him to be one of the most caring and thorough clinicians I have ever met. His history, resume, expertise and personality are outstanding. He has gone out of his way to write to textbooks on the management of diabetes. I have met several people who have done this, none of them have the aptitude and kind personality that Dr. Unger has. When I receive a referral from him, I receive an informed history that is certainly the most thorough and relevant to the particular question we are aimed to ask of any available. I know many primary care physicians, Dr. Unger is the most interested and attentive of any I have met. Every referral comes with a detailed letter. When I receive referrals from other institutions and individuals, it is up to me to seek for further information and this is often done at a great time investment on my part. There have been instances in which I will call him without any foreknowledge, I will mention a patient's name and he will be able to recall, in detail, all recent events, labs, and other features of the patient without any reference to a medical chart. I don't know anyone who can do this. When I interact with others, I am invariably asked to hold momentarily while they search through their charts to receive a mental update. This isn't exactly a sign of poor performance for others, in fact is is reasonable, but the fact that Dr. Unger is able to accurately describe in many unprompted details the situation cannot be understated. I believe it is a reflection of his attention. It is not distracted, he has the appropriate energy in the right place. Needless to say he knows his patients very well, he interacts with them outside his clinic hours regularly, he always knows what I am doing for them as we work together. I have never met a primary care physician so exhaustively involved in a patient's medical care. When other patients come to my clinic expressing concern about their current primary care provider, Dr. Unger the first thought to come to mind. I have been through this experience many times. Inevitably I receive a telephone call from the patient I referred to him with very positive thoughts, the overwhelming majority are highly satisfied.

He also took the time to explain the changes in the medication to us, so we fully understood how, when, and why he took a particular approach to addressing a new health concern. The type of care he provides is worth every penny.
