At TalkDoc, we understand that having a mental illness is an extremely isolating experience, where most people don't even believe you suffer from a mental illness, or downplay what that might mean in your life. Patients who suffer from severe mental illness such as psychosis often go untreated until they hit the breaking point because of this. Talkdoc provides mental healthcare to patients on Medicaid, in more than 5 counties in California, through our professional corporation partnership. TalkDoc has established itself by having the best outcomes in the entire country for Medicaid. We see mental health hospital utilization rates of 0.16% per year, as compared to 3%-4% for the general Medicaid population who sees a mental health clinician. We've helped thousands of people live healthier and happier lives. We are moving from a family business to high-growth startup, and we started that three months ago. Our technology mission is to be the safest and most private form of healthcare, that keeps patient data private long-term, while still offering the most advanced technological solutions, such as AI clinical assistants in workflows.
