GROW EARNINGS: Clients often tell me that what I am to them is really a business therapist! That means I work holistically with my clients to help them turn just about any kind of challenge they are having in their business, be it family management or other staff related challenges, slipping profits, modernization, a lack of buying and inventory skills, or a lack of marketing...into an opportunity for positive growth. Having also worked in and run the kind of businesses I consult on, I'm intimately familiar with most of the pain points you're experiencing. Creating a thriving profitable business in the horticulture industry can be very challenging- be it a plant shop, garden design business, landscaping services, plant growing operation, you name it. I love the horticulture industry and have spent more than 30 years discovering its nooks and crannies. That means I know my way around most of its moving parts and how to grow profits. It also means my extensive expertise and experience can be put to use in a variety of ways to help you grow your practice or revitalize a struggling business.
If you need targeted strategic guidance to start, grow, or SAVE your plant-based business, brand, or marketing, I can help. Improving perception of value is key and we all want to earn more for the important services and products we provide.
SCHEDULE 20-MINUTE MEET & GREET: Looking for professional horticulture or business advice and want to find the right fit? Let's schedule a short meet & greet so I can learn about your goals and you can get a sense of how I work. I do not provide direct consulting during these calls. Please secure a consulting session in my shop, or contact me about ongoing consulting, rates, and billing terms, if you're ready for targeted advice on your business or product.
GROW PLANTS: I'm also here for you when you need expert horticultural consulting to support greenhouse growing, commercial design, install, or maintenance projects and properties. I also provide limited residential consulting, and anyone can book a virtual consultation with me.

"As a multi-passionate horticulturist with many irons in the fire, I was working for a more clear focus and vision for my small niche business…but was just stuck. That’s when I connected with Leslie Halleck through a private consultation. Leslie listened while I spoke about my business and the unique work that I do. After hearing my thoughts and looking through the work I shared with her, she offered constructive feedback that affirmed my strengths and teased out opportunities that I wasn’t yet seizing on and was even overlooking. Leslie’s smart perspective, straightforward approach, and mentoring support is informed by her years of varied experience in the horticulture industry, and I trust her input. It was helpful to run my ideas by someone like Leslie and get her outside perspective. Leslie is part horticulture maven, part counselor, part cheerleader/advocate. Inspired by our conversations, I was able to recenter myself, refocus on my primary goals for my business, eliminate elements of my business that weren’t serving my main vision, and even pursue additional credentialing that will strengthen my skills and push my business’ momentum forward. Connect with Leslie soon!"

"The career counseling process taught me to focus on the value of my experience, knowledge, and skills and not the value of the job. Whether you are just starting your career or 20 years in, Leslie will give you the tools to help you work through short-term and long-term career goals with a focus on work-life balance. Often the fear of change will keep an employee stagnant in a job that he/she no longer finds rewarding. In other cases, the fear of rejection when seeking a promotion or trying to validate the monetary value of your skills. Whatever the case may be for you personally, I found this process to be invaluable in the next phase of my career."
-Kristen Kennedy, Branch Manager YC Nursery
