Summit Tree Care provides a variety of tree care services for residential and commercial clients in Sonoma, Marin, and Napa Counties, handling everything from basic trimming and maintenance to tree and shrub removals. The company utilizes a wide range of state-of-the-art equipment to streamline the tree care process as much as possible, including aerial lifts, brush chippers and stump grinders.

Owner Bob Alvarez credits much of Summit Tree Care’s success to the expertise and longevity of his employees, many of whom have been with the company since its founding more than 20 years ago. “Our customers like that we’ve had the same employees since the beginning,” he says. “It says a lot about how we treat our employees and how they treat our customers in turn.”

Summit Tree Care provides the same crew for every job, which allows its tree care specialists to develop a familiarity with each property and its trees that ultimately ensures a high level of customer satisfaction and loyalty. “Our customers really appreciate how safe, prompt, reliable and courteous we are,” says Mr. Alvarez. “With the combination of our modern equipment and highly experienced employees, our customers find great value in the services we provide.”

Our surveys of only verified real customers produce the country’s most accurate ratings of local companies. Summit Tree Care scored Highest in Quality and Helpful Expertise and passed the credential-based checks to earn Diamond Certified.

A Star Equivalent Score is calculated for each verified customer rating by weighting the 1–10 Quality score, the YES/NO Loyalty (intent to return) score and the YES/NO Helpful Expertise score. If Helpful Expertise wasn’t surveyed or didn’t apply, it’s simply not shown.
