I visited the office located in South Pasadena City, and it was easy to find. The address is Building 1609, Pasadena Ave S Street, Suite 4C, and it's well-marked. The dermatologist's office, Mahoney Dermatology, is a bit tricky to spot because of its location in a building with multiple offices. However, it's worth the search. The reception area is small, but clean and nicely decorated. I appreciated the wheelchair-accessible features, including the restroom, parking lot, and entrance. However, the office could benefit from a more welcoming atmosphere, which is somewhat lacking in the current design. The staff was friendly and helpful. One issue I encountered was that the building's parking lot is not clearly signposted, making it difficult for patients to find the office. I was able to schedule an appointment by calling the phone number, +17275300920, and speaking with the friendly receptionist. The website, https://mahoneydermatology.com/, provides basic information about the office, but lacks more detailed information about the services offered. Dr. Matthew Mahoney is the dermatologist on staff, and I was impressed by his professionalism and expertise. Overall, the office has a lot of potential, but could improve on its design and accessibility.
