About Us

I have been a Certified Arborist since 1991 and actively involved with the Tree Care Industry for over 34 years. I am a Registered Consulting Arborist with the American Society of Consulting Arborist. At the present time, I am the Assistant Division Head in the Urban Forestry Division for the City of Los Angeles which manages one of the largest street tree populations in the nation.  Prior to coming to the City of Los Angeles I was the owner / operator of Neighborhood Tree Service and shortly thereafter I started consulting on a part time basis.  In 1999 I started consulting on a regular basis and that's when we changed our name to Neighborhood Consulting Arborist.  Then, due to the increase in Court Case work we started our current company Tree Case Management in 2010.




I've been involved with the Western Chapter International Society of Arboriculture in the following areas: Judging and assisting with the ISA Certified Tree Worker / Arborist exams; Proctoring for the Certification process; The Regional Conference Chair for the entire Western Chapter; Champion of an initiative of the chapters strategic plan; Coordinated the Western Chapters first Workday event; as well as various other committees throughout my tenure. I was Director on Board for the Western Chapter International Society of Arboriculture from 2005 through 2010. Then, President of the Western Chapter International Society of Arboriculture in 2010/2011. I am a Registered Consulting Arborist through the American Society of Consulting Arborist and I'm an academy graduate, a Certified Arborist / Certified Tree Worker / Utility Specialist with the WCISA, a licensed Pest Control Advisor and Operator with the State of California, and have been involved with the tree care industry for more than 34 years. 


My career goals have been the following: to continue to provide relevant education and training,  promoting outreach and involvement to youth, multilingual and diverse groups, resulting in professional growth and development within our industry; work to express the importance of volunteers within our industry and the benefits to our membership as well as our constituents throughout the Cities where we work; work on a committies, with other arborist, to develop industry standards relating to sidewalk repair, alternative options, tree preservation, tree retention, and root pruning standards; outreach to more homeowners and/or business owners through field level training and on-hands demonstration; and work with other arborist to continue to improve our industry and ensure that our constituents receive the benefits they deserve.



Tree Case Management (TCM) is dedicated to the enhancement of your community and the protection of the environment as the preeminent authority on matters related to root and infrastructure damage, tree preservation and retention, and tree and plant health, while ensuring through our expertise and objectivity the safety, preservation, functionality and beauty of your natural surroundings. 
Trees in our developed environment present a challenge, requiring careful planning and vigilant maintenance. The shared public trust of governments, businesses and homeowners is to ensure that tree plantings grow, thrive and remain safe. When a problem occurs—if a tree causes damage or becomes a public safety hazard—a source for advice and mediation is often needed. This is the role of TCM to bring a comprehensive, objective viewpoint to the diagnosis, appraisal and evaluation of arboricultural issues.
As Registered Consulting Arborists we are called upon to advise in the most challenging situations that necessitate experience in the science and practice of arboriculture, as well as specific expertise in the practical, ethical and objective role of the consultant. 
We strive to be the arboricultural experts of choice to assist law firms, insurance companies, utilities, and developers, municipalities, landscape planners and architects, homeowners, individuals and organizations coping with disaster mitigation, and others requiring authoritative knowledge and perspective on trees and plant life. 
In addition to court case work, we specialize in root analysis, structural stability and the overall evaluation of the root collar area in determining various needs, or addressing various concerns. We perform our excavation with the use of an Air-Spade which uses a patented supersonic nozzle that focuses the air “like a laser beam” to break up the soil. The soil can then be easily removed from the excavation site without damaging the roots. Air exiting the nozzle is at twice the speed of sound (approximately 1300 mph) which allows for best digging conditions with the effort of tree preservation in mind, even in the hardest soils. And the best of all is that it is not harmful to the roots or the adjacent infrastructure.


The Air-Spade can be used for just about any application that requires digging around sensitive roots or objects. We use the Air-Spade for the following applications:

  • Root analysis for litigation cases 
  • Root collar excavations 
  • Soil compaction relief 
  • Diagnosis work 
  • Treatment of diseases 
  • Trenching for underground utilities 
  • Root pruning 
  • Root structure analysis 
  • Transplanting of trees 
  • Educational work on roots and plants 
  • Construction of sidewalks 
  • Construction of house foundations


As you can see the Air-Spade is an outstanding tool if your ultimate goal is tree preservation, or if you need to identify the ‘actual’ cause an alleged dangerous condition caused by a tree root. For more information on the Air-Spade applications and benefits see the Air-Spade link or contact us directly via this web site. Businesses, government agencies, organizations and individuals engaging us as their Consulting Arborist have the confidence that we adhere to the highest standards of professional practice.
