Sandra Zimmer - Public Speaking and Communications Coach
Sandra Zimmer

Sandra Zimmer is your public speaking and communication coach.

Sandra believes that each of us has natural gifts and talents and a unique way of expressing that is compelling to others. Sandra founded the Self-Expression Center from her desire to help people develop confidence to express themselves more freely. As an acting student, she had experienced how difficult it was to free her acting talent in classes based on negative criticism. As a public speaking professional, she had felt the awful fear of stage fright and performance anxiety. Sandra wanted to provide transformational programs in an atmosphere where people could overcome fear of public speaking and feel safe enough to open up and explore their natural abilities to present, perform and communicate.

Sandra holds an M.A. in Theater from The University of Houston, a Doctorate in Esoteric Philosophy, a B.A. in Psychology from the University of Texas and is a Certified Lessac Voice Teacher. Additionally, she has more than 30 years of experience in personal growth and spiritual psychology. She also received acting and directing training from theater giants Jose Quintero, Gerald Freedman, Robert Lewis, and Michael Shurtleff.

Sandra has been guiding groups and individuals since 1976 at the Self-Expression Center and in business settings, teaching public speaking, voice training, communication skill training, acting classes and much more. Her teaching credentials also include The University of Houston Drama Department, Houston Community College Speech Department, The State Bar of Texas Continuing Legal Education and The University of Houston Law Center. She has designed group-training programs for Walter P. Moore Engineering, FKP Architects, Welcom, KBR, Brown & Root Services, Lockheed, Star Enterprise, Neill Corporation, Pointsmith Point of Purchase Management and Dub Miller Ford. She has trained individuals from hundreds of companies, including Compaq, Siemens-Nixdorf, Exxon-Mobil, Amoco, Baker Hughes, IBM, Coca-Cola Foods, Shell Oil, Shell Chemical, Marathon Oil, Conoco-Phillips, SYSCO, KHOU-TV, KUHT-TV and several law firms.
