Degrees and Certifications:

Mrs. Mylla Harvison

Hello.  I'm Mrs. Harvison and I am the business/technology teacher, as well as the Electives department head, for the LHS Harmon campus.  After graduating from North Texas State University with a Bachelors degree in Business, I began my teaching career in the Irving ISD.  After eight years at Nimitz High School I decided to stay home and raise a family.  I have three grown children and a beautiful new granddaughter.  When LHS Killough opened, I returned to teaching.  I've been at LHS Harmon since it opened and really enjoy working with ninth and tenth grade students.  My own children are all graduates of LHS and I think it, along with its feeder 9 & 10 campuses, is the best school in Texas!


The business department offers a variety of classes on a rotating basis.  These include Money Matters (Personal Finance), BIM (Microsoft Office Suite), Web Tech (html and css), Touch System Data Entry (keyboarding), Global Business, and Banking and Finance.  I'm located in room 2111 and can be reached at 469-713-5201, extension 6893.  You can also email me at:
