Lorenzo Chavez Two-day Plein Air Workshop

The PSC Western Slope group is very excited to offer a 2-day workshop with Lorenzo Chavez in August 2024. 

Where:  S-Cross Ranch in the Glade Park area, south of Colorado National Monument (private property, so not searchable on google maps) It is approximately 9 miles east of the Colorado/Utah state line on DS Road

When:  Friday, August 23 and Saturday, August 24, from 9am-4pm both days

Cost:  $250 per student.  There is a required minimum number of 12 students and maximum number of 17 students

Lorenzo is a well-known figure in the pastel world here in Colorado.  The following paragraph is from Lorenzo’s website:

“Lorenzo Chavez was born and raised in the southern-most point of the Rockies in New Mexico. His first inspirations and foundation as a young artist were formed by the local landscape and the art history in New Mexico. Lorenzo now makes his home in Parker, Colorado and uses this location as a base to travel and paint the American West and Southwest. Through the years, while searching for subject matter, he realized there are many similarities throughout the Rockies. The deep blue of the vaulting sky, majestic cloud formations, rabbit brush, chamisa, pinon, pine and juniper, the willows that line the stream banks, the granite in the mountain ranges, aspens and the endless seas of grasses are continuing inspirations.”

Lorenzo has a long list of international, national, and local representation and awards – a listing of professional accomplishments can be found on his website

The workshop will be plein air, and will be held at the S-Cross Ranch in the Glade Park area, south of Grand Junction.  (In the event of bad weather, there will be an indoor location available).  It’s a unique and bucolic location – irrigated pasture and old buildings and ranching equipment, surrounded by the high desert cliff formations typical of the Uncompaghre plateau.  There will be many opportunities for painting, complete with instruction provided by one of the masters of painting the desert landscape typical to this part of Colorado.

Also please note – lodging options in the Glade Park area are limited to camping.  The closest hotels are in Grand Junction.

DESCRIPTION: “Connecting Eyes, Heart, Hand: Amplifying YOUR Voice!”

A comprehensive overview of combining intuitive and artistic techniques to illustrate what you observe (eyes) with your emotional response (heart), in order to express it with your hand.

Strengthen your voice as a pastel painter in this 3-day intensive where you will dig deep into how to express your subjects using this intuitive approach while working with your unique voice. In this class you will be learning how to use the key principles of successful paintings to compliment your personal style. We will also explore materials, methods, and techniques to help you represent your subject. This is about learning to paint in your own unique voice—not a formula seeking to teach all students to paint the same way. Through discussion and abundant studio time, you will be learning your personal path toward being the one-of-a-kind artist that you are.


Contemporary American Realist Natasha Isenhour expresses her emotional response to unpopulated spaces with an edgy lonesome starkness that defines the very essence of her work in oil and pastel. Isenhour exhibits throughout the southwest and teaches sold out workshops to students from coast to coast and internationally each year, both in plein air and in studio.

2022 highlights include Award of Excellence in the OPA Regional Exhibition in Dallas, TX and a 5 week solo museum exhibition at the Taos Art Museum and Fechin Studio in Taos, NM.  

2023 Terry Ludwig Pastels LLC released “Natasha Isenhour Essential Alchemy” set of 60 pastels.  In 23 she worked a second year as faculty for PACE, Plein Air Convention and Expo in Denver, CO, and was Featured Pastel Artist for the Mendocino Open Plein Air event in CA. Isenhour participated in her 3rd year at the 17th Annual Borrego Springs Plein Air Invitational in 2023 where she walked away with an Honorable Mention, an Award of Excellence in Pastel and was the Quick Draw winner. Lastly, Isenhour was awarded an Honorable Mention in the OPA Juried Online Show.

Representation includes: Ventana Fine Art, Santa Fe, NM, and Abend Gallery Denver, CO

Affiliations include: Signature Member of Pastel Society of America, American Women Artists and Plein Air Painters of NM.  Distinguished Member of Pastel Society of NM and member of OPA and the Salmagundi Club NYC.

By registering for this workshop, the participant accepts the intent of the workshop description, and also accepts reasonable adjustments to logistics and content due to unforeseen circumstances. 

We always feel badly when a personal emergency arises, however we must strictly adhere to this policy. ALSO, refunds will not be issued due to illness, emergencies or events beyond our control. No-shows will not receive a refund, regardless of the circumstances. If you drop out of a class once it has started, you will not receive a refund. We reserve the right to cancel any workshop, in which case we will make a full refund. Trip cancellation insurance is strongly recommended.

Rocky Mountain High Plein Air Workshops with Liz Haywood-Sullivan

Both workshops are now sold out. Wait lists are available. See below.

Information from Liz:

Painting the Rockies with Water Vistas – Part I and Part II 

This destination workshop is an amazing opportunity to paint in one of the most breathtaking locations in the US. We will be heading up into the inspiring views of the Rocky Mountains north of Denver near Granby and Grand Lake. Each two-day workshop will be at a different location and provide different painting opportunities. Take one or both workshops. Both plein air workshops will include lessons on how to select better compositions on location, how to paint different types of water, and the use of aerial perspective in grand vistas. I will demonstrate every day and then will work with you one-on-one at your easel.
