About Us

    Oatsiva Enterprises was founded by two pharmacists,
Michelle Cassumbhoy and Carson Au, in 2017.
Together they have acquired clinical knowledge from major
Australian public and private hospitals in addition to extensive retail experience
in careers spanning almost twenty years.
The flagship product Oatsiva Concentrated Oatmeal Cream
was formulated based on this combined experience.
The inspiration for this cream was to provide a high quality,
pharmacist formulated, intense moisturizer for a wide range of
consumers at a reasonable cost.
