With a love for working, helping and dealing with people she landed in the healthcare field. She loves getting people where they need to be in life to achieve greatness.

Along with a love for helping people she loves the outdoors, biking and going to the beach. Fishing is a passion of hers.

Her favorite part about working at Bay Choice is seeing the transformation of patients from surgery and how surgery has changed their lives for the better!

We are glad she is a part of our Bay Choice Family


Mayra Avellaneda is our medical assistant. She has been with our practice for a while and is a great addition to our Bay Choice family.

Mayra was born in Mexico but grew up in Baytown, TX. She is a part of a big family, being that she is the oldest of 11 children (8 girls and 3 boys).

In her free time, she likes to relax and go out with her friends. Mayra works part time at Bay Choice while going to school full time. She is very thankful to have a manager, like Beth, who will work with her school schedule!

Mayra enjoys seeing the patient transformation. She is the one that follows up on their criteria to get them approved for surgery. Explaining how excited she gets when they have been approved for surgery and seeing their weight loss transformation as well.

Gaining knowledge about weight loss and how to keep a healthy lifestyle has been another highlight for working at Bay Choice.

We love having her in our Bay Choice family.
