Providence Patient
Easy to talk to. Thoughtful responses to my ?s.
Providence Patient
The doctor, nurses, office staff, and lab techs were all friendly, respectful, and timely. My appointment started right on time and I didn't feel like I wasted any time at the office. Dr. Nienaber was thorough, thoughtful, and helpful. The Wilshire office is closer for me, but I was unable to schedule an appointment there on the app which is inconvenient. Parking should also be validated.
Providence Patient
The office is great! From entering for my appointment to scheduling my next appointment. I have been receiving excellent care with Dr. Mathew!

Providence Patient
I have worked with Dr. Nienaber for over 4 years now. Not once have I ever felt rushed in our appointments - he would always take the time to make sure he answered all of my questions and that I was feeling okay about what we had talked about. I always felt heard and understood. I always felt comfortable enough to ask questions I might not ask another provider. I always felt like he was immensely knowledgeable about whatever topic we discussed. Let me put it this wayI've moved a couple times within the last 3 years, so I'm not as close distance-wise to his office, but I decided not to change my PCP to a doctor who might be closer by because that's how much I value the work and care that Dr. Nienaber provides.
Providence Patient
The best experience I've ever had at a doctor's office. Outstanding customer service and the doctor actually listened to my priorities and concerns for the first time ever at a doctor's office.
Providence Patient
I have had excellent experiences with my doctor.
Providence Patient
I love Dr. Matt. He is terrific!
Providence Patient
Amazing doctor the best!
Providence Patient
The doctor was well-prepared and had reviewed my medical history in relation to the issue I was asking about in advance. He answered all my questions, did not dismiss any of them as "silly," and explained why he came to his conclusions. He also told me what to look for in the future. Couldn't have asked for a better response or more thoughtful treatment.
Providence Patient
Everyone was wonderful and efficient. No waiting at all!
Providence Patient
Dr. Matt was very caring & welcoming. Will be transferring my care to him.
Providence Patient

Providence Patient

Providence Patient
I feel lucky to have found this provider years ago and continually receive fantastic care and respect
Providence Patient
I've been seeing Dr. Nienaber for a few years now, and I have to say the overall majority of my experience has been fantastic. My ONLY bone to pick was during the summer of 2022 when I was in need of a cardiology referral, but could not get one for what ended up being over a month. Only after an ER visit with notes that I needed to see a cardiologist did I receive my referral. That was disappointing. Again though, other than that, he's been a great provider these last several years.
Providence Patient
I finally found the right place when I found Dr N and the supporting team.
Providence Patient
Everyone in Dr. Nienaber's office is professional, friendly and excellent at their job! Dr. Nienaber is the best!

Providence Patient
This group is fantastic. Every single member I have ever interacted with has always been great. Courteous, efficient, and compassionate. Dr. Nienaber is my all time favorite physician. He has a wonderful way of interacting. He's informative, intuitive and always has a positive way of trying to encourage me to take better care of myself without coming across as critical or judgemental. Like many people, I enter the Drs office with a bit of fear and dread, but always leave feeling positive and motivated and I think that is the highest praise for a physician.
Providence Patient
This is the very first time I have been able to meet the doctor and whilst I feel he is going to be very good for me most of these question do no apply to us since I have never met him before
