Clarity Pediatrics feedback?

Does anyone have experience working with Clarity Pediatrics, which provides behavioral therapy for parents of kids with ADHD? We're considering working with them to help us better parent our younger elementary child who we suspect has ADHD. Would love to hear about any experiences folks have had. 

Would also be curious to hear recommendations for therapists who help parents better support kids with ADHD, as well as the broader family system. My partner and I are in need of a serious parenting reboot and would like to work with someone on an ongoing basis.
