The Best!
“I've been in practice for six years and have gone through four previous billers; needless to say I did a lot of research before choosing Valley Medical Billing Services. 
Heidi has consistently been the most reliable, efficient and timely medical biller I have had and would highly recommend her to anybody. My percentage of unpaid claims are lower than I ever thought was possible and her tenacity balanced with has gone far in my working relationships with patients and insurance companies.
Her services have paid themselves many times over, and I no longer spend my Fridays chasing down unpaid bills.
Thanks Heidi!”
