We are excited to announce that our team and assets are moving to Siris.
“This partnership marks a significant milestone for Siris. By integrating CCCxA’s assets and welcoming its talented team, we are expanding our capabilities and reinforcing our commitment to excellence. We chose Siris because of its strong Christian beliefs and the numerous awards they have won for leadership and service. Together, we will continue to innovate and provide unparalleled service to our clients.
At CCCxA, our primary mission is to advance the design of integrative functional medical hospitals through rigorous research and data analytics. My background in econometrics from the Naval Postgraduate School equips us with the tools to analyze and optimize these designs effectively. Additionally, we are committed to assisting our findings to the new VA Secretary, Douglas Collins, to further enhance services for our veterans. This integration allows us to bridge services and expand networks for integrative functional medical hospital services, ultimately improving the quality of care and support provided to those who have served our country.
Thank you for your trust and support as we embark on this exciting journey. We look forward to serving you with enhanced capabilities and renewed dedication.”
