Philip Bennett

President Elect

City of Snoqualmie, in Snoqualmie, WA

I am the President Elect for the Pacific Northwest ISA. I work as an urban forester for the City of Snoqualmie and as city arborist for the City of Clyde Hill. My daily work includes all physical aspects of caring for trees, including planting, pruning and removal. I also work on program development, grant writing, plan review, developing partnerships and educational programs.

Before becoming an arborist, I worked as an environmental educator and wilderness guide. I continue to be passionate about learning and teaching. I came into the field of arboriculture vocationally, and have learned along the way. I believe it's important to keep learning, as ideas and research are constantly evolving.

Lyle Feilmeier


Bartlett Tree Experts, in Clackamas, OR

Commercial Arborist Representative, Bartlett Tree Experts, in Clackamas OR. I have been a Certified Arborist since 1991.

I am a current member of the ISA, PNW-ISA, TCIA, and ASCA. In 2007, I became a Board Certified Master Arborist (BCMA) and a TCIA Certified Treecare Safety Professional and hold the ISA Tree Risk Assessor Qualification. I am currently working toward becoming an ASCA Registered Consulting Arborist.

I live in Clackamas, Oregon with my wife Dawn and my daughter Ayla. My passions are my family, photography, and bonsai.

With today's ever changing environmental concerns, I see arboriculture becoming a more and more important industry and profession. I feel we are only breaking the surface of the potential this industry has. We are seeing continual improvement in all facets of the industry from climbing techniques and equipment to the way we assess tree risk. As an industry, we must stay abreast for the betterment of both the arborists we work with every day to the public who relies upon us to provide sound and tested information. I plan to be a part of the advances and challenges that come our way.

Katie Lompa

Member Services

Oregon Department of Forestry, in Prineville, OR

I am excited to be in the PNW-ISA membership services director position (as of September 2013).  During my term, I hope to see Chapter membership and involvement grow.

In 1998, I received my ISA Arborist certification, moved to Oregon, and began my involvement with the Chapter.  As an ISA certification proctor, I have coordinated ISA certification exams in Central Oregon since 2000.  From 2008 to 2011, I held the PNW-ISA regional education coordinator position for the Bend/High Desert Regional Education Center.

Since moving to Oregon, I have worked for the Oregon Department of Forestry Urban & Community Forestry Assistance Program as a community assistance forester.  In this position, I provide urban forestry leadership, education and technical services to cities, other government agencies, and non-profit/civic organizations located within the 18 Oregon counties east of the Cascades.

Before arriving in Oregon, I worked for the Maryland Department of Natural Resources - Forest Service as a Forest Conservation Act regional coordinator covering the State’s Eastern Shore.  This was after earning a Bachelor of Science in Urban Forest Resource Management from The Ohio State University (Go Buckeyes!).

My husband and I reside in Central Oregon on 10 acres of western juniper and sage brush.  Our children (aka pets) - Clyde, Willie, and Petunia - plus 10 chickens and a few turkeys (“guests” of honor each Thanksgiving!), keep us laughing.

Living the dream!  I hope you are too.

Nadia Chan

Public Outreach

Hi, my name is Nadia Chan and I was elected to the Board in September 2013 as the Director of Public Outreach. I have been a Certified Arborist since 2005 and a Certified Tree Risk Assessor since 2007. I have a Bachelor of Science in Forestry and currently work for the City of Surrey as the City’s Natural Areas Coordinator. My current job involves managing over 1500 ha (3700 acres) of natural areas in an urban environment. From the management of forest health, trail systems, invasive species and wildlife, my day-to-day work can be extremely varied. This can bring a lot of challenge, but also a lot of rewards!

I live in Vancouver, B.C with my husband and two children. In my spare time I enjoy gardening, playing soccer and hockey and spending time with family and friends.

Susan Munro


I have been a member of ISA and PNW-ISA since 1981 and am a Founding Member of the Chapter. I was first elected to the Board as Vice-President in 1982, serving one term, and have been Editor of our Chapter newsletter, Pacific Northwest Trees, since 1984. During this time, I have watched the Chapter grow from a small group of arborists driven by a solely volunteer leadership and scraping by on a few thousand dollars a year, to a thriving, fully staffed nonprofit organization with an annual budget that has approached half a million dollars!

I obtained a B.Sc. degree in Ornamental Horticulture at UBC and worked for a small landscape architecture/urban forestry consulting firm in Vancouver for several years. My employment path then took me away from arboriculture. After five years as office manager for the Outdoor Recreation Foundation of BC, I worked in a similar capacity at Boys and Girls Clubs of BC for 16 years. After a year off when that organization relocated to Kelowna, BC in 2007, I now works as Resource Development/Project Assistant at Boys and Girls Clubs of South Coast BC.

When not gathering articles or learning new computer programs for the newsletter, I enjoy reading, listening to music of all genres (from classical to jazz), and attending ballet, opera, and theatre. I am a member of the Capilano Flute Choir (an amateur flute ensemble), and a long-time enthusiast of Jazzercise. Having acquired a serious "travel bug" a few years ago, I have since visited France, Spain (8 times and counting), Cuba, Argentina, New York City (now an annual event), and Malta.

Wendy Robinson

Tree Fund Liaison

I live in beautiful Bend, Oregon on the east side of the Cascades and work for the City of Bend as an urban planner. I became an ISA Certified Arborist in 1996 and was appointed to the PNW-ISA Board to fill a vacancy as Secretary that same year. During my tenure as Secretary, I helped update the Chapter bylaws in 2005 and again in 2010 to bring them into conformance with current Chapter practice and state law. I frequently volunteered with Jim Barborinas on TREE Fund events. After a short hiatus away from the Board, I accepted the appointment as TREE Fund Liaison in 2007 when Jim stepped down.

I am currently the Chair for the TREE Fund Liaison Committee. This is a two-year appointment and my term ends December 2013. As TREE Fund Liaison, I am always looking for new and fun ways to raise money for the TREE Fund and the Chapter Public Outreach program. We are very fortunate to have a membership that is generous with both their time and resources.
