What has been your greatest success while teaching at Our Lady of the Lake University?: 
I make concerted efforts to help non-mathematically oriented students understand that mathematics is learnable, that it is not the enemy, and can be very satisfying.

What do students like best about your class?:
I think students appreciate my caring attitude, my willingness to work with them, and my efforts to make mathematics understandable.

Length of Service at OLLU?: 20 years

What are some of your former students doing now?:
More of our graduate math majors are teachers than any other single type of professional. Others are in graduate programs or jobs in civil service or industry, especially computer-related occupations. In recent years, many who have become teachers return to OLLU for Masters degrees in Education in Integrated Mathematics.
