Jose Martinez

Owner/Senior Climber

I have been in the Tree Care industry for over twenty-four years! I began working for a contractor doing power line clearance where I learned to climb and most importantly complete the job as safe as possible. Those power lines are no joke!

Now I am continuing my education to become Arborist Certified, and serve as the lead climber and trainer for my company, where I take care of anything from fruit tree pruning to hazardous tree removals. I look forward to bringing my knowledge and expertise to complete any job as safe as possible!

Arcangel Martinez

ISA Certified Arborist / ISA Tree Risk Assessor / Wildland Firefighter Type 2

Born and raised here in Santa Rosa, I grew up in the industry along side my father. From the age of eleven I was dragging brush on the weekends and during my summers away from school. I sought out other careers to try and move away from this line of work, but I always came back.

I decided to stick with what I knew best, and follow a career in arboriculture. Now as an ISA Certified Arborist, ISA Qualified Tree Risk Assessor, and Wildland Firefighter Type 2, I use my knowledge and education to give our community the best tree care possible.

From Hazard tree removals, to fire risk management and everything in between. I put forth the importance of proper tree care in our business, and our community. As I continue my education majoring in Agriculture Plant Science, I look forward to best serve you, in the county, which has been home all my life!
