My experience with Dr. Eric Yoon was pleasant. First, impressions is that the office is nice and clean. I didn't have to wait more than 5 minutes to be called. The staff are really friendly! Dr. Eric Yoon had amazing bed side manners. Asked me a lot of questions about my symptoms, did a few tests, and took a breath test the same day, which was great and time efficient.
Dr Yoon is fantastic! Wonderful to speak with, very clear in his thought process, and very thorough. His staff members were warm and friendly, and the appointment felt validating and gave me clarity for next steps moving forward in my health journey!
Today was my first time seeing Dr. Yoon. On entering, my first impression was the cleanliness, comfort, and modern look of the reception area which were all very pleasing to my eyes.
Once I signed in, there was really no wait time, as I honored my 10 am appointment.
The Receptionist and other staff member were very pleasant and professional.

What an incredible doctor. Truly listens to your concerns and takes the time needed. Wonderful experience!
I had been in severe pain due to fissure for weeks, and it was affecting my daily life. Dr. Eric Yoon quickly diagnosed my condition and prescribed the perfect medication. Remarkably, by day three, I was pain-free and could finally live comfortably again. I would highly recommend Dr. Yoon to anyone in need.
Updated: Slight confusion on the billing part (that got resolved). Aside from that, Dr. Eric Yoon and his team were great. Very professional and empathetic. I had an endoscopy done and they did a really great job of explaining the procedure, following up, prescribing the right medication, and more. For anyone curious, my stomach was very sensitive to any sort of red meat or fatty/greasy food. I would always get sick but after the procedure with Eric Yoon and going on medication for 30-60 days, I no longer have that issue and it's amazing. Thank you so much!!
Incredible experience. Went in with an emergency, thorough new patient exam and in office bloodwork, left with insurance approved testing scheduled for the next day, and Dr Yoon's bedside manner since has been amazing, even when I call with annoying questions. I will be referring.
I’m very happy to be working with this doctor. I have had a lot of doctors in the past be dismissive but he seems to really care and is willing to explore various options. Looking forward to continuing to work with him. Love the option of telehealth visits!

Great service. Was seen very quickly and extremely professional

During a remote visit after my colonoscopy Dr. Yoon explained the results to me clearly and answered all my questions. He also allayed some fears I had.
