Our history
Mr. Marinho’s passion for landscape development began in 1987. With his passion for people and in one attempt to cultivate his desire to serve, he started a landscape design and maintenance business. What his clients get nowadays is his personal and pointed attention to detail coupled with more than 30 years of experience.
Over the decades Mr. Marinho has completed projects both large and small; all with the same commitment to perfection and client satisfaction. Founded on trust and dependability he continues to manage his business with a focus on building relationships with his clients. Betsy Allen, landscape designer, and consultant brings a partnering organization to Greenstone that compliments Mr. Marinho commitment to client needs.
Mr. Marinho and Mrs. Allen’s collaboration has created a team that clients find thoughtful, engaging and personally interested in every detail of beautifying their homes.
