Everyone was very friendly and care about you. I will definitely like being a patient here. Amy Joy listened to my concerns and spent time with me explaining everything to me. I was happy with Kaitlyn and the front staff that I interacted with.

I have really bad anxiety regarding going to the doctor. Amy Joy, NP was a delight to work with. She made me feel very safe and calmed my fears. I felt very comfortable with her. The other staff, especially Amber, were all wonderful as well! Great people, great professionals. I feel like I am in good hands with them.

I am extremely happy with my decision to switch to Valley Professionals! Dr. Siddiqui is compassionate, knowledgeable, and very thorough. The behavioral therapists are top notch. They communicate well between each other, and with the patients. It’s been a refreshing change of pace for my medical needs!

Amy lynn joy it's been the best doctor I've ever been to she's amazing and helpful and she treats me like a human being rather than just another patient to get through the day she wants to help me and figure out what's going on and try to provide the right treatment I've been to a lot of doctors and seen a lot of specialists but I've never been treated this well before their office offers so much more like chiropractic psychologists eye doctors and they even have a social worker that can help you when you're in financial trouble I recommend this office
