"Johan is truly the 'constant gardener'.  He is very knowledgeable about any and everything landscape and truly has a passion for what he does. He puts 100% into everything he does and on top of this, he is very kind and approachable. I would recommend him to anyone looking for gardening/landscape design in the Berkeley/Oakland area." -Erica B., Oakland

"Johan Kalhstrom, of Avant Gardener, is an award winning landscape designer who creates landscape works of art. I've seen him transform small urban spaces in San Francisco and weed infested backyards in Oakland, into welcoming verdant places that any homeowner could only dream of. I especially love how Johan's encyclopedic knowledge of indigenous plants allows him to create eco-friendly gardens that don't need watering and save the owners major $$. Without reservation Johan Kahlstrom gets my highest recommendation." - Ken M., Berkeley

"Johan designed, planted and maintains my little garden in the Mission.  Prior to Johan I had a 10 x 3 strip of "outdoor" space.  Basically a sad, weedy place.  He transformed into a sculpted jungle.  Warm, cozy, and a real retreat from the city.  I love it. I will be working with him on another upcoming project, a small kitchen garden. Can't  wait to get it started." - Chris M., San Francisco
