Real reviews from Walnut Creek Psychiatry patients on Google.
I've had an outstanding experience with this psychiatric clinic. From the moment I walked in, the staff consistently demonstrated compassion, professionalism, and genuine care. They take the time to truly listen and understand what their patients are going through. The providers are knowledgeable, thorough, and supportive. They never make you feel rushed or dismissed. Instead, they work with you collaboratively and respectfully. I'm grateful for the excellent care I've received and would highly recommend this clinic to anyone seeking mental health support.
After years of seeing psychiatrists who didn't do their due diligence, I experienced almost immediate relief the first time I met Erin. Every time a med hasn't worked, she's reassured me that I'm not out of options and we'll get it figured out together. She stays up to date with recent meds entering the market and helped work with my insurance to keep costs as low as possible. I can't say enough good things about Erin and highly recommend her as a provider.
Dr. Haley is outstanding. She is by far the best listener I've ever met in the mental health field. The office staff is so friendly it's unbelievable! I would not hesitate to choose Walnut Creek Psychiatry. She empowers her clients, is so friendly and thorough!
