I have been seen by pain management for many years. The office staff, medical assistants and physicians have provided a great patient experience. If you have an appointment they see you on time and if they are short by a staff member the team in this office works well together. The staff are great at the Germantown office. I really want to recognize Maxine for getting to know the patients by name and being attentive to their needs. I highly recommend this office for your pain management needs.

Since I started going to pain management in Germantown MD, I’ve been fortunate to have two doctors in this office who have done a great job at listening to my health issues and then tell me exactly what I need to do to manage and at times elevate whatever physical pain I am dealing with.

Doctor Nicholas Tannous, MD & Doctor Carlos Marrero-Prats, MD, I can say have been such important parts of my heath journey. They have helped me manage the severe pain that I deal with because of RA and Sjo. Listening to what I had to say and then giving me their plan on how to move forward. They both have great bedside manners, and they truly cared about what I am dealing with. There is no cure to my illness but there are ways to manage the pain. I appreciate the both of them for everything! I would recommend the both of them to anyone who may need a doctor in their field.

Dr Yoon was awesome. Through his diagnostic work, he identified my issues and explained them so I could understand. As he was doing the testing, he was letting me know what I as about to feel. I was very comfortable with the entire appointment, checking, arrival, testing and departure. Easy facility to access. Plenty of handicap parking on the lower level of the garage, right at the elevator.

A big thank you to Dr. Marrero, Nurses Kevin and Uju. I came in for knee pain and ended up getting a cortisone shot. From the first time I visited until the day of my treatment the entire staff along with Dr. Marrero were amazing and their bedside manner and professionalism is a 10/10. I would recommend them to any and everyone. I did not feel rushed and I felt well taken care of. Their level of professionalism is second to none. Thank you to everyone of you for your level of excellence, kindness and professionalism.

Moved up here from NC..first time coming here..Doc, hit right on point...what, I told him about my pain, so (Aggressive) every day PAIN I was having Day by Day..My doctor from north carolina didn't listen TO ME, he was giving me the same Pain medicine for 5 years, and it (stop) working 4 me. The doctor here changed THAT PAIN MEDICATION...Plus gave me a SHOT for "INFORMATION" I promise you it WORK FOR ME. He gave it to me at 10am in the morning. I felt a DIFFERENCE later on that EVENING.. So much RELEASE of PAIN in my KNEES and they ALSO gave me a knee BRACE. I took off my right knee...that EVENING and I was WALKING so much BETTER.

I've been to quite a few doctors for my back, none have compared to here. Dr. Marrero is such an amazing doctor. He takes time to get to the proper solution and not jump right to surgery or meds. And he cares. The staff is absolutely wonderful!!
