Medical Provider

Amanda Hutton Parrott, NP DPT has demonstrated a wide variety of interests, all of which are focused on the human body and its wellbeing. Her post graduate education includes an MFA in dance, from UC Irvine. After a career traveling and performing with Dallas Black Theater, she developed an interest in how to deal with the physical impairments and repetitive movement injuries suffered by dancers in performances. That interest led to a Doctor of Physical Therapy at New York University and work with dancers in Broadway productions. She returned to San Francisco and began her practice there, but discovered that the scope of physical therapy was narrower than her interest in the medical field. Her broadening interests plus volunteer work at Grote Schuur University Medical Center in South Africa, the infectious disease wards, led her to UCSF’s MEPN program.

During her academic tenure at UCSF, Amanda created and completed a residency in infectious diseases in Capetown and surrounding townships in South Africa  then graduated with a master in science and an NP license. Since that time, she has worked as an NP at UCSF 360 Wellness Center for eight years.

She also is a clinical consultant for the National Clinician Consultation Center. She approaches her practice by evaluating and treating the entire person, encompassing physical, psychological and spiritual balance. She strongly believes that medicine is a science based on research, but is also an art as it is individualized for each person.  Amanda plans to continue her practice at 360, and to extend her career into global health.

In addition, Amanda spends time with her family, particularly her two young sons, as well as teaching and participating in outdoor sports and dancing.

Outreach Coordinator; Peer Advocate; PrEP Coordinator

Michael got his start in healthcare by volunteering at age 16 in San Diego for a Centers for Disease Control and Prevention-funded program that focused on youth of color ages 13-24, which transitioned into a full time position as a Health Educator. Through hard work and commitment, Michael moved to Northern California where he continued his dedication in serving the community as an HIV Testing Coordinator and eventually a Public Health Community Specialist for the Santa Clara County Department of Public Health. Michael later moved back down to San Diego to start his journey into education, which led him to San Francisco.

After graduating with a BA in Psychology and Minor in Human Sexuality from San Francisco State University, Michael found a new line of work in the housing crisis San Francisco currently faces. These positions ranged from a Case Manager for families that were formerly homeless, to HOPWA (Housing Opportunity for People With AIDS) Housing Specialist that works with housing subsidies, to Shelter + Care Case Manager that encompasses three areas: substance abuse, mental health, and HIV/AIDS. Michael is very excited about the transition back to working in the HIV field, as this is his passion.

When Michael isn't working, he can be found doing any of the following: cooking (and eating) dishes prepared from scratch, spending time with his partner and dog, and playing videogames from all the generations of systems.
