Maria Elena (Mia)


Mia was born in Tucson, Arizona, but moved at the age of 3 back to Las Vegas where the majority of her extended family lives.  She is pretty much a native to the Vegas area.  She then pursued her B.S. Athletic Training degree at Chapman University in Orange, California as a student athlete (Division III soccer all 4 years while obtaining her degree).  She became a certified athletic trainer in 2009, but knew her journey was not complete.  She graduated with a Master of Physician Assistant Studies at Touro University in Las Vegas, Nevada in November 2012.  Upon graduation, she was then hired at Advanced Orthopedics and Sports Medicine with Dr. Timothy Trainor in December 2012.  She has been his “right hand man” since.  Mia prides herself in the care of her patients and being a key member of the Trainor team.  When she is not in the clinic or in the operating room, she enjoys time with her family.  She is a busy mama of 2 toddlers that love the outdoors.  They love to hike and visit national parks.  She also enjoys kayaking with her husband, when the Vegas sun is not baking them.
