To Whom It May Concern: 

​

Vantage Medical Billing has been working for my anesthesia practice for 30 plus years. Our business relationship dated back to 1983, starting out with Sam and then Alan 10 years ago when senior Ryono retired. 

Like the father, Alan provides very effective and efficient collection services and he is always loyal and puts the client's interests first. Further, he is willing and instrumental to help negotiating my contracts with HMO, hospitals and insurance companies. 

In our lengthy relationship and sometimes challenging situation, I never doubted his hard work and honesty. I even recommend Vantage Billing to my anesthesia as well as surgical colleagues. 

For a brief time of one year between August 2017 and August 2018, my contract with Foothill Presbyterian Hospital was absorbed by CVAMG, I did use ABED for collection that was dictated by the contract. 

Now, I am working at Glendora Surgery Center. I am coming back to Vantage Billing just like the good old days. 

Vantage Medical Billing is an ethical, trustworthy and very capable company. Alan and his company will prove to be an excellent asset to your practice management. 

I strongly recommend Vantage Billing without any reservation. You may contact me if there are any further questions.

To whom this may concern,

I am an obstetric and gynecologist practicing in Los Angeles since 1982.  

After working with various billing services, I was introduced to Alan and his father over 30 years ago. Their service is reliable, prompt, professional and fair.  I could not find one bad thing to say about them. This applies to all the years they have been helping my practice.

Please contact me should you have any questions.

It is with much enthusiasm that I am writing to recommend the services of Alan Ryono at Vantage Med Billing. 

​

Vantage Med Billing provided services for my practice for 13 years and I was always completely satisfied with their management of my billing and accounts receivable.  They did an excellent job negotiating some of our contracts and making sure that reimbursements were correct and timely.  Vantage Med Billing would always be available to answer any questions I had about billing or reimbursements.

​

I'm happy to recommend the services of Vantage Med Billing.  If you have any questions please feel free to contact me.
