Founder
I got my start in Medical Billing by forced accident. While working as a Registered Behavior Technician and then an Office Manager for a small ABA practice, the need arose for my role to take on the medical billing for the providers. Within a few months, I was hooked. Tackling the complicated process of submitting claims and appropriately receiving reimbursement became like a puzzle—one I couldn't get enough of.
Since 2019, I've specialized in ABA-billing, which means I'm fluent in the details that matter: CPT codes, authorization utilization tracking, timely filing windows by payer, and the specific challenges of billing for behavior services.
I've worked with practices ranging from solo BCBAs to multi-provider agencies, handling everything from initial credentialing setup to cleaning up years of aged receivables.
In 2025, I launched Thrive Claim Solutions to support more providers who deserve better than a biller who ghosts them when denials pile up.
how i work
I'm not a large billing company with rotating staff. When you work with me, you work with me—the same person, every time.
I respond to emails and calls (no ticket systems or phone trees). I explain things in plain language. And if I don't know something, I'll figure it out instead of making excuses.
Your billing shouldn't feel like a black box. I keep you informed, answer your questions, and make sure you understand what's happening with your revenue.
