In her spare time, Ms. Macshadiya enjoys spending quality time with her husband and 4 rapidly growing children, her very loyal companion Daisy (4-year-old rescue Chiweenie),  reading, listening to music (and singing along as best as she can), traveling, and giving back to her local community through volunteering.
