    Join Dianne Panarelli Miller for a 2-hour demo where she will discuss her process, materials and inspiration. 

    Dianne Panarelli Miller is a world reknown artist painting in Canada, Bermuda, and Europe. She is an award winning Boston-based "Plein Air Painter" of color and light and is a signature member of the New England Plein Air Painters and is a "Copley Master". Her approach combines the classic atelier training of the "Boston School", with a mastery of technique of her own personal style expressed through the harmony of color and design. The original Boston School way of painting seeks to combine the truth of impressionist color with good drawing, sound composition and skillful paint handling. It's leading exponents included Edmund Tarbell, Frank Benson, William Paxton, Joseph Decamp, Philip Hale, R.H. Ives Gammell. Gammell was a turn of the century Boston Museum School pupil of the first three men and later consulted with Paxton. Robert Douglas Hunter and Robert Cormier (with whom Miller studied ) were students of Gammell. David Lowery and Robert Moore, also students of Gammell rounded off her studies.

    Impressionist painter Margaret McWethy studied art history and biology

    at Swarthmore College. Since graduating she has sought teachers who base their art on training, careful observation, and understanding. Margaret, a native of Maryland, now lives and paints in Massachusetts. Since moving here, she has spent time studying the mechanics of painting. "I have never really left my science background behind. I am always interested in how things work visually, and more importantly, how to convey this information most effectively to students. My classes are a series of experiments and my students are willing participants.”

    Cathy McCarthy is a self taught mosaic artist. Her first experience in mosaics was a life size shark that she installed at the bottom of a swimming pool in Southern California, when she decided to just try out a new form of art.  From there on she was hooked and has created hundreds of mosaics including murals, a life size mosaic cow, and her most popular mosaic heart rocks.  “I will mosaic anything that stands still!”  

    Cathy‘s mosaic work uses ceramics, stained glass, hand made tiles, and various found objects. Cathy’s formal education was in graphic design and illustration and now works primarily in pastel and acrylics.  Her Mosaic work is secondary but actually her favorite medium to work with.  “I’m always working on a mosaic in between my other work.  It’s just fun!” Cathy lives in Scituate with her husband Kevin and her dog Samson.
