Brian Yantorno - General Manager and Owner

Brian’s first job at the greenhouse was filling trays with soil each day after school when he was just six years old. His grandpa (Pops) would stay close by to make sure he was doing the job right and clean up behind him so that he wouldn’t get in trouble with his dad. Growing up he did a lot of different jobs from filling soil, moving plants, small facility maintenance work and making truck deliveries with his ‘Pops’. Brian graduated from Regis University in 1997 with a Bachelor of Science degree in Business Administration. He has worked here full time since college and has done just about every job there is to do along the way. After graduating from college he ran our shipping and transportation. From there he moved on to young plant sales, but found it was hard to be on the road all the time with two kids at home under the age of three. He found his niche doing Production & Purchasing and soon became the Operations Manager. For a time, he was also our Head Grower. Today, he is our General Manager and like the four generations before him, his focus remains on growing Powerful plants and treating the customers and employees like family.

Over the years, Frank has served on numerous industry boards and was inducted into the CNGA Hall of Fame in 2011. Frank has always had a contagious energy and passion for our industry and like the generations before him, keeping the customer happy has always been a main goal. Frank passed the torch of the leadership of Center Greenhouse onto his son, Brian, in July of 2013. Frank still serves on our Board of Directors alongside our CFO, Dean Waterman and his sons Ken and Brian. He is now finding time to have coffee in the morning with some of his comrades and also enjoying a game of golf each Wednesday. The torch has been passed on to the 5th generation of the Yantorno family to continue growing on our Centennial Farm.

Tiffany Lawonn - Operations Manager

Tiffany started working for Center Greenhouse in August of 2006.  She had previously worked in banking for nine years and was ready to make a career change.  “I essentially traded in one green industry for another” Tiffany jokes.  “This one is much prettier though.”  Tiffany handles the ordering of our URC (Un-rooted cuttings) and inputs and manages all production into our computer program e-picas.  Without her, we wouldn’t know what to grow or when to start growing it.  She likes being able to walk out into the greenhouse in the Spring and be surrounded by the beauty of all the flowers.  “It definitely makes the stress of ordering and entering the production for it worthwhile.”  She enjoys picking out her favorite new flower growing in the greenhouse each year and designing her container gardens for home around it.  Tiffany became a mom this past year and loves spending her free time with her son Owen, her husband Noah and the rest of her family hanging out together.
