Patient Reviews
Dec 23, 2023
I had the flu about 3 weeks ago but couldn't seem to shake a deep chest cough. I gave into going into our local Urgent Care. I feel so lucky to be seen by Dr. Trephan. She is friendly with great 'bedside manners'. Dr. Trephan was thorough in checking my breathing and vitals while listening to my concerns that lead to the correct diagnosis. She confirmed her thoughts by having her tech taking an Xray of my lungs. I thank her for showing me the Xray so that I could learn how clear lungs should appear. I wish that Dr. Trephan could be my primary doctor.

Board Certifications
What’s a board certification and why is it important that my provider has one?

A board certification represents a provider’s dedication to ongoing training in one or more specialties, including the completion of intensive exams. While not all specialties have board certifications, if your provider does have one they’ve taken the extra step to master their specialty and to keep up with the latest advancements in their field.
