Patient Reviews
Aug 17, 2025
Very happy with Dr Vallejos care and attentive nature. He’s very thorough, thoughtful and knowledgeable. Had an immediate sense of comfort that I’m going to finally get on right track. Being new to Dr Vallejos I was feeling discouraged and very frustrated just trying to book an appointment. I spent months trying to be seen by a hepatic specialist at Oregon Clinic only to be bounced around put off told I cannot only be seen at the clinic I was originally seen at (Televisit). Had Sadly it took an inside resource to get me an appointment. Respectfully I understand this means requesting a change of patient care internally however it should be an option.
