Alisa Kharis

MXTReality Junkie

Alisa is the business development manager at MXTReality/MyPad3D, a digital media company, specializing in augmented and virtual reality solutions (AR/VR). Her background is in law, social work and mediation. Alisa’s passion project is using VR as therapy for physical and mental health issues. “It’s easy to see how AR/VR will change the fabric of our daily lives in the future. I want to see it used to help heal people and give them a better quality of life. Ideally, we can eliminate the need for addictive substances with negative long-term consequences, often as bad as the disease.” To that end, she currently focuses her outreach to organizations that work in partnership with SCI, as well as ALS, and Parkinson’s’ patients. The ultimate goal is to help empower people limited by mobility issues. AR/VR can help level the playing field.

Outside of work, Alisa enjoys kayaking, hiking, international travel, road trips, and performance art.
