Instructors’ Biographies:



Michael Adams:  I am a free-lance illustrator, designer and a fine artist. I enjoy painting birds, wildlife, landscapes and portraits.
I am a graduate of Philadelphia College of the Art, where I taught Illustration for 14 years. I teach watercolor techniques at GNAL.


Jo Ann Cooksey Bono I am a multimedia artist and teacher with a degree in Elementary and Secondary Art Education from Longwood College in VA.  My background includes experience in journalism and advertising.  Currently, I teach watercolor, collage and drawing to adults and children and enjoy my work and my students very much.  I am a signature member of the Philadelphia Water Color Society and the National Collage Society.  My goal is to encourage my students to create dramatic compositions and to discover a personal artistic vision.
Ann Brennan:  All I have ever wanted to do is paint and create. I attended PAFA right out of HS, so I could do just that.  My art and the medium I work in is as varied as my style.  I contribute this to my love of art and creating.  I am constantly pulled in different directions and fascinated with subjects which for me is all apart of the journey.


Joy Cognata:  I’ve been involved in the arts one way or another throughout my entire life. When I was 5 years old I began with music, but in my teens I realized the freedom and expression that painting allowed me, so I chose to pursue fine art as a passion and a career. I have studied art at Montco and received my Bachelors Degree in Fine Art from The University of the Arts. I enjoy painting with watercolor and I have a fascination for experimentation whether it be with paint or sculpture. I am currently an art instructor at Painting with a Twist in Skippack, and am so fortunate to continue to pursue my love for art after graduation. My greatest recent accomplishment was illustrating a 4-part children’s book about a bunny rabbit titled, “The Adventures of Fuzzytail” that was published late 2016.


Lauren Keller Daddona:  The process of playing with paint is visually exciting to me. Always asking “What if” leaves me open to new ways of approaching the process of art. Watermedia takes me on a journey and in turn my viewers enjoy the journey also. I value the emotional responses they share when viewing my work. I am a signature member of The Philadelphia Watercolor Society, The Pennsylvania Watercolor Society, and The Baltimore Watercolor Society.

Teresa DeSeve:  Teresa DeSeve  was born in 1948 in Beloit, Wisconsin. She studied painting at PAFA, and earned a BFA in painting from Rosemont College. Teresa is a Signature member of the Pastel Society of America, and the Philadelphia Watercolor Society. She works mainly in the pastel medium as a figure painter.

Pat DeVirgilis:  I paint in all mediums, supported by a strong background in drawing, design and illustration. I have taught privately and at the university level for many years. I hold a BFA degree from Marywood University with further study at the Art Students' League, NYC and with nationally recognized master artists.


Nathan Durnin:  I am an artist specializing in oil painting and drawing. I received my Master's Degree from the Pennsylvania Academy of the Fine Arts where I honed my skills both in my technique and the narrative within my work. Galleries in which I've exhibited include Artist's House, WP Gallery in Philadelphia, and Gallery 222 in Malvern. Along with teaching at GNAL, I also teach painting, drawing, and watercolor at Delaware County Community College. My classes offer students training in the fundamentals of drawing and painting as well as intermediary challenges.
Mary Vogel Lozinak:  Professional Artist, Summer Art Camp Instructor and rubber stamp designer.
Doug Tweddale:  I have been an artist my whole life. I remember being nine years old and oil painting with my Uncle Lester Gallagher, an artist from the Midwest who loved painting the sand dunes of Lake Michigan. For the last 30 years, I have been a pastel artist, and for half of that time I have studied with Master Painter Albert Handell. Now that I have retired, I have the wonderful opportunity of making painting my first priority as I travel this beautiful country with my wife Sue. So far, we have been on two three-month extended trips to many National Parks out West. A story of our 2015 journey and my travel art work was just published in the August issue of the Pastel Journal. During our travels, I conduct "Living the Dream" Plein Air Workshops to share my artist’s knowledge and experience with students as we enjoy painting our treasured National Parks.
Anne Whalon:  Anne received her formal education at Rosemont College and Villanova University where she earned a Bachelor of Fine Arts Degree. She later studied textile design at the Philadelphia College of Textiles and Sciences (since renamed Philadelphia University) and The Fabric Workshop in Philadelphia. She then worked in New York City as a textile designer and fabric stylist. After NY she returned to the fine arts and now works exclusively producing and teaching fine art. Anne is a signature member in the Pennsylvania Watercolor Society and the Philadelphia Watercolor Society. Anne paints in both watercolor and pastels. She is an award winning artist and has received many awards for her paintings.



Arnold Winkler: I was born in Möllbrücke, a little village in Austria at the beginning of World War II.  My father instilled the love for photography in me at the age of 4 years.  It is still my hobby of 68 years and counting.  After working for an international computer company and taking pictures all over Europe, I finally ended up in Blue Bell.  After retiring in 2004, I started exhibiting my photos and digital art at GNAL and joined in 2006.  Photography is still my hobby, and I started teaching an introductory class a few years ago, and I learned the basics of Adobe Photoshop.  I love sharing my knowledge of this complex program.
