Founder & principal consultant
Kasey Harman
Kasey's horticultural roots run deep—literally. Growing up on her family's citrus farm in southwestern Arizona, she developed an early appreciation for how plants, people, and the desert environment interact. That foundation ignited a lifelong passion for cultivating healthy landscapes and thriving ecosystems.
Kasey earned her degree in Plant Biology from Arizona State University, specializing in Urban Horticulture. Her career began with hands-on experience across multiple sectors of the landscaping industry, giving her a well-rounded understanding of plant care, design, and management. In 2008, she founded Harmony Horticultural Consulting to bridge the gap between science-based plant care and the practical realities of landscape management.
Over the past 18 years, Kasey has become a trusted leader in diagnosing plant health issues and guiding property owners, estate managers, and landscape professionals toward long-term, sustainable solutions. Her expertise includes water management, soil fertility strategies, pruning best practices, and integrated pest management. With her guidance, countless landscapes have become healthier, more resilient, and more beautiful year-round.
Beyond her consulting work, Kasey has been an active leader within the Arizona Landscape Contractors' Association (ALCA) for more than 25 years and currently serves as Education Committee Chair. She is a frequent speaker for the Arizona Community Tree Council (ACTC) and the SHADE conference, and over the past two decades she has volunteered across the tree and landscape industries, teaching more than 100 professional classes to contractors, arborists, and landscape professionals throughout Arizona.
Today, Harmony Horticulture is a respected consulting team serving the Phoenix metro area and beyond, known for its proactive, science-driven approach to plant care. Kasey's blend of academic knowledge and practical field experience continues to make her an invaluable resource for clients seeking healthier, more vibrant landscapes.

Where It All Began
Roots in the Citrus Groves
Kasey's horticultural foundation was built long before her consulting career — on her family's citrus farm in southwestern Arizona. The values learned there still shape every assessment, every recommendation, and every client relationship today.
"Growing up on the farm, I learned that every plant tells a story — and that understanding the land is the first step to helping it thrive."

Kristen Battafarano
Horticultural Consultant
Kristen's horticultural career began with an unexpected turn — after earning her BFA in illustration and graphic design, a chance encounter with an organic farmer sparked a lifelong passion for plants and stewardship. Over the past three decades, that passion has evolved into a career spanning horticulture, arboriculture, landscape management, ecological restoration, education, and consulting. Her experience includes serving as a Biological Scientist with the National Park Service at Mount Rainier, teaching at the Desert Botanical Garden and Arizona State University, and authoring hundreds of landscape evaluations and management plans for homeowners, HOAs, and commercial properties — including international work for the Ayla Oasis Hyatt Regency Golf Resort in Aqaba, Jordan. She believes healthy landscapes begin with careful observation and informed stewardship.
