"Before Chris Callahan came into consult for my practice we were struggling to get the basics right in terms of people, process, and patient experience. Chris was able to quickly identify weakness within our current staff and assisted onboarding new members. She was able to organize the workflow in the office to better support our needs and cut costs. As a result of these improvements I have been able to dedicate more time to patient care. Chris is an efficient problem solver and has become trusted and valued partner to my practice. Chris has a gift of clear communication and understanding people. My office and team owe much of our success to Chris Callahan."
