Our Team

Glenda Parkes DipTP MRTPI

Glenda co-founded Tyler Parkes in 1996 and is one of the driving forces behind the long-term company strategy. With many years’ experience as a professional planner, she successfully delivers planning strategies for Clients on complex proposals across the country.


Glenda works alongside Clients, assembling teams and developing proposals to overcome significant challenges on the most contentious sites. She provides a solution-focused approach to projects and her personal approach to managing complex projects builds trust and garners engagement in the process.  As a consequence, Glenda has secured consent for many highly complex residential, employment, hotel, mixed use, and public service projects throughout the country.


In her down time, Glenda and her husband have enjoyed their move to the countryside and renovating, reconfiguring, and restoring their partly Elizabethan home.
