My workshops are an extension of the joy and excitement I feel when I create my own art. As a working artist, I experiment with new approaches, new techniques and media to keep my art fresh.


Since 1990 I have shared my evolving knowledge and expertise with thousands of students, tailoring classes to various skill levels. I attribute much of my teaching success to my life as a working artist. I embrace student interaction, and I use a step-by-step experiential approach in all of my classes.

Highlighted below are my In-Person course and workshop categories. Check back for updates, or sign up to be first to learn about classes are they are added to the calendar.

ART & ILLUSTRATION Courses in Colorado

Over the past thirty years, as an instructor at the Denver Botanic Gardens School of Botanical Art & Illustration and developer of my own successful art workshops and programs, I’ve learned a bit about teaching! 


The goal in all my courses is to inspire you to learn beyond what I teach in the classroom. To do this, I focus on your artistic strengths and weaknesses, devise exercises that build upon your strengths, create a non-competitive environment in which you are encouraged to learn from others, and gently nudge you to explore on your own. You make mistakes. You learn from your mistakes and gain new confidence. Pushing yourself a little more and excited to develop additional skills, you learn to trust your insight and your drawing hand. You discover your own artistic “voice”. It’s that simple!


My courses incorporate:

  • Instruction that provides step-by-step, straightforward learning

  • Handouts that reinforce and expand upon class instruction

  • Live demos and original artwork to visually communicate technique and process

  • In-class exercises that reinforce new skills

  • One-on-one critiques that meet you where you are in the learning process

  • Group critiques to illustrate common challenges and good techniques

These All-Levels Courses include: 

  • Pencil 1

  • Advance Pencil

  • Pen & Ink 1 & 2

  • Transparent Acrylics

  • Light on Form

  • Mixed Media

  • Perspective

  • Composition

  • and other subject matter or media-specific courses
