Green ForesTree is the consulting practice of Quatisha Oguntoyinbo-Rashad, an ISA Certified Arborist with 16+ years of South Florida field experience. We work only as advisors. We do not perform tree work, so that the recommendation in your report is the one we actually believe in.

Quatisha Oguntoyinbo-Rashad
Principal Consulting Arborist
Quatisha works across the full arboricultural arc, including municipal urban forestry, private estates, and construction sites, over more than 16 years in South Florida. That range is the point: the questions that bring clients to a consulting arborist rarely have a single, narrow answer, and the value of an independent expert lies in being able to see the situation from multiple angles before committing one to writing.
The practice is intentionally small. Engagements are handled personally, from the initial call, through the site visit, to the report on your desk. That continuity is how technical detail makes it from the field into a document that holds up to outside scrutiny.
Quatisha brings over 15 years of experience in arboriculture, urban forestry, tree preservation, permitting, and environmental resource management. Her professional background includes serving as Chief of Environmental Resources for the City of Miami, where she has helped manage and protect the urban forest through ordinance enforcement, staff training, and certification standards. She has also served in leadership roles with the ISA Florida Chapter and the Landscape Inspector’s Association of Florida, and her work has been recognized by the ISA Florida Chapter and the City of Miami. Through Green ForesTree, she provides professional consulting arborist services grounded in practical experience, technical knowledge, and a commitment to responsible urban forestry.
The consultant who does not profit from removal.
A tree service earns more from removal than from preservation. It earns more from a large treatment program than from a small one. That is not corruption. It is structure. But it does mean that the recommendation you receive from someone who performs the work is, inevitably, shaped by what they are positioned to do next.
A consulting arborist sits outside that loop. We assess and advise. We do not perform removals, prunings, treatments, or installations. Our incentive is to be correct, because correctness, written down and signed, is the entire product.
That is also why our reports read the way they do: facts observed, methodology stated, opinions clearly identified as opinions, and the basis for each opinion shown. Whether the document is going into a building permit file or onto an exhibit list at trial, it is written to be read by someone who is going to push back on it.
