Camera Capsule procedure... Easy peasy!
I waited a total of maybe five minutes from walking in to front desk. The two ladies sitting there right away helped me. I went and sat down and waited two or three minutes. Saw PA right away she is always nice and explains everything and answers all my questions. It was quick but productive all the way thru until I left.
Dr Serna was so kind and he really cares about what is going on with you. I found his office staff to be helpful and caring.

I enjoy seeing everyone that works with Dr. Ramirez. They are so friendly and have a good bedside manner. Dr. Ramirez makes me feel like I'm talking to a friend. She is very thorough and great at following up after tests andol procedures. My only complaint is that wait times are a bit long, but only some times. Thank you Dr. Ramirez for about 18 yrs. of excellent service!!!
Great Experience! Thank you so much Dr. Antonio Serna, M.D.😊
