Jake Leman

Project Manager

Singing Hills Project Manager - Jake Leman

Jake has the unfortunate experience of growing up with his “roots” firmly sunk in the landscape industry. Pressed into slave labor at an early age, he knows no other life. (Well – maybe not exactly slave labor, but… ) Seriously… he began working in the field in 1998 at the age of 13 and has developed a fine sense of customer service and the capability to install complex high-end landscapes. He is a Landscape Industry Certified Technician and an ICPI Certified Paver Installer, with extensive experience in both residential and commercial projects.

Tifani Leman

HR Director

Singing Hills HR Director - Tifani Leman

Tifani Bahr, (now Leman), is our very capable HR Director-in-law and also responsible for safety and risk management. She came to Singing Hills in 2008 after earning her Bachelors of Science in Human Resource Management from Kansas State University. While earning her bachelors, she worked as the Assistant Human Resource/Business Manager in the Department of Grain Science. Having been raised in a small town in southern Kansas, Tifani likes being a part of the family atmosphere at Singing Hills. She also loves living in an area with such a mild climate and can be outdoors close to year round. One of Tifani’s great passions is to help people communicate and come to understand and respect one another. She believes this is part of the equation for most of the conflict between people, especially in the workplace. Tif works hard to help open doors of opportunity for our company family.

Kevin Haeflinger

Install Project Manager

Singing Hills Install Project Manager - Kevin Haeflinger

Kevin began working with Singing Hills for the 'twentieth' time in July of 2014, his first time being the summer after his SR year of high school. He worked on and off for us during his summer and winter breaks while attending Colorado State where he received his Bachelors Degree in Education. Besides working as a full-time teacher at Aurora Hills Middle School for the last 6 years, Kevin ran his own landscape company, Grade A. He has temporarily left the education atmosphere to use his passion for education and knowledge in the green industry to manage his crews and jobs. We believe Kevin is an excellent addition to our team!

Ed has a degree from the school of hard knocks

Ed Stoller

Estimator

Singing Hills Estimator - Ed Stoller

Ed has been an invaluable addition to the Singing Hills team. His varied background in farming, grain elevator maintenance and management, topsoil supplier, construction project management, and physical plant maintenance has prepared him to have an excellent grasp of both the big picture and the details that it takes to make a project successful. His ability to think through and envision a project enables us to put together the best possible project plan and price it accordingly. Ed and his wife Boni are enjoying life in Colorado. They have three sons living at home and one daughter who just happens to be married to our son Joel. Joel and Kristi take care of six boys at the CVE orphanage in Magdalena, Sonora, Mexico. Ed and I are proud co-grandpas of their daughters, Soraya and Selah. ☺

Steve joined our Singing Hills family in September of 2012 bringing with him over 30 years of experience in the landscape industry. Steve is a Landscape Industry Certified Technician. He also holds a Qualified Supervisor license with the Colorado Dept. of Agriculture in several categories. Sometimes, people in our industry are labeled tree-huggers, but Steve is just a hugger. (You may need to watch out! ☺ ) His naturally cheerful demeanor is a joy to work with. As a 4th generation Coloradan he has experienced everything Colorado’s environment has to offer, from shoveling snow during the blizzard of ’82 to managing irrigation and landscape issues during the 2001-2002 drought.
