Andrea Ewert

Chief Executive Officer

Andrea has been in Healthcare for over 15 years. After developing strong relationships with clinicians and patients in the Central Valley, she realized people wanted more from a provider. Clinicians expressed a need for “ease of use” service and consistency. Patients want access to a company that cared about them and took time to assess their needs and deliver services accordingly. “We’re here to service the patient, not the shareholder”
