Important Announcement re: After Hours Advice Line

As you know medical costs continue to climb and we are currently confronted with the need to change, and pay significantly more for, our after hours advice calls.  We are committed to providing thorough and timely medical advice for your family, including after hours. 

After an extensive search and review process, we are pleased to announce that starting on 2/1/24 we, along with all UBCP-affiliated practices, will be offering after hours advice through a new group, Anytime Pediatrics.  

When our office is closed, including on holidays, you may call Anytime Pediatrics for advice at (623) 663-1707. As before, if your child needs an after-hours appointment, appointments can be made at GoHealth in Oakland. One important change to note is that we will bill your insurance for these calls, and that these calls may be subject to a co-pay, co-insurance, or deductible, if not covered by your insurance. 


Prior to making an after-hour call, the providers at Berkeley Pediatrics recommend that you look up your child’s symptoms on the AAP website symptom checker:
