With more than 20 years of experience in both Case Management and Cost Containment, ASA developed an in-depth cultural understanding of Latin American and Caribbean Health Care. Currently, ASA has more than 300 in-network Medical Providers within 42 Countries in the area.

Valeria Gonzalez
Chief Case Manager

“I started working for ASA as a Case Manager back in 2017. It has been very rewarding to be able to have a positive impact on the lives of patients and solve and manage complicated cases for our clients. No two days or weeks or months are the same! Every day is different and I love the variety. At the beginning of this year, I promoted and as part of my role I now also lead and supervise the Case Management team. We have a great team of professionals that bring together the medical, cultural and operational expertise and experience to manage almost every case in Mexico, Latin America and the Caribbean. We are happy to help!”r
