Unsure of travel time, I got there 1 hour early. Figured a wait but took me right in. Was in and out quickly. Dr. Steinhauser was very efficient and pleasant. Extremely pleased with my visit.

Dr Christina Steinhauser was very professional and answered all of my questions. I felt comfortable and reassured. But for the front receptionist Katelin Ubiarco she was quick, rude, impersonal and not welcoming. She rushed me and had attitude with tone while speaking to me. I will not be visiting this office ever again because I never want to deal with her again.
