Providence Patient
I have been going to Mission/Providence for about 25 years when I started seeing Dr. Joe Nguyen. Since then I can say that even though every physician I have made contact with has a different personality they have all treated me with the utmost dignity, respect and kindness. I consider some of them a friend that I would help in a time in need as I feel that they have probably saved my life whereas other doctors would have not taken my test to the next level. I use to live near Mission/Providence and now live over 30 miles away and I refuse to go anywhere else. In the near future I will be moving about 80 miles away and will continue to see my incredible team of doctors at Mission/Providence.Going on to staff, It Is very heartwarming to see the beautiful people that work the different desks and offices greet me with a smile and Incredible (Only one insulting experience.) customer service. I mean this from the bottom of my heart and anyone can contact me from your facility if you want further information.
Providence Patient
I like the appointment reminders emailed / texted to me.
