John Mariconda – President

John Mariconda has been in the construction industry for 39 years and has over 30 years of construction management to his credit. He started in the industry in 1972 as a union carpenter working on high-rise residential projects in New York City, while he attended night school trying to earn his business degree. In 1976 he and his family relocated to Southern California and John continued to work as a union carpenter in the housing and commercial construction industry.

In 1980, John started his first position on the management side of the construction business as a concrete superintendent on high-rise projects for a developer in the Los Angeles who he had been working with for the previous 2 years. By 1986, John became the Vice President of Construction for Tucon Development Company. At Tucon, John oversaw a team of Architects which designed all of Tucon’s projects and a construction team that consisted of Project Managers, Superintendents, Foreman and Workers. Tucon self preformed Concrete, Framing, Drywall, Plumbing HVAC, Fire Protection and Electrical. Some of the most notable projects John worked on during this span were the LAX Hilton, Anaheim/Disney Hilton, Pacific Stock Exchange in Downtown LA, and the Wilshire Estina project in West LA, which was an 18 story 250 unit high-rise condo project.

In 1990, John decided to start his own construction company (John Mariconda Construction Company), which he relocated to Hawaii in 1991 at the request of one of his clients. His primary business in Hawaii was design and building of custom homes and small commercial projects. He remained in Hawaii until island fever got the best of him at the end of 1996, when he relocated to Phoenix to be closer to his daughter and her family.

During February of 1997 John started working for Summit Builders, Inc. as an estimator and was quickly promoted to Senior Estimator. Summit Builders is a large Commercial General Contractor based in Phoenix that also builds condominiums and apartments. After moving from the estimating side to the operations side at Summit, John was asked to go open an office in Southern California for Summit Builders in early 2000. After successfully getting the office up and running in Southern California, John returned in 2002 to the Phoenix office to oversee all of operations for Summit Builders, which he did until April of 2005. The most notable project at Summit Builders was a twin 18 story 554 unit condo project that included a three story subterranean parking garage, which was located in Long Beach, CA.

In May of 2005, John took on a new challenge as Vice President of Construction at D.R. Horton, Inc’s, Phoenix Urban Division. D.R. Horton was and still is the largest home builder in America and this Division mainly concentrated on infill and high density for sale housing projects.  By February of 2006 John was promoted to Division President of the Phoenix Urban Division. The Phoenix Urban Division built, sold and closed 760 homes in 2006, 1020 homes in 2007 and 885 homes in 2008. The notable housing project at D.R. Horton was the Villagio at Tempe, which was a 742 unit project located on Rio Salado and the Loop 101.

John left D.R. Horton in October of 2008 to start his own construction and home building company. John currently holds a General Contractors license in three states (California, Hawaii and Arizona) and operates under the name of Fortress General Contracting Inc. and Fortress Homes, LLC.

Jason Ratke – V. P. Operations

Jason Ratke spent 4 years as a union certified electrician which is followed with 16 years in the residential and multi-family construction industry. His career began with Thomas Electric in 1991 as an apprentice doing minor residential and elementary wiring. In 1992 he received his union certification from the local IBEW and began managing electric projects for Thomas. In doing so he was exposed to a variety of construction applications and jobsite conditions throughout the Valley.

In 1995 Jason was approached by DR Horton and encouraged to apply for an Assistant Superintendent position. He was hired and held that position for 18 months.  As construction demands grew in the Valley, he was promoted to Project Superintendent and began running his own projects. As a Superintendent, he oversaw all aspects of construction from pad preparation to final walk-throughs with customers while creating job schedules, delegating work to assistants, other employees and sub-contractors. He was also responsible for scheduling and interacting with city, county and OSHA inspectors to maintain industry standards.  During his time as a Superintendent, he managed the construction and development of projects ranging from 1600sq ft single family homes to 4000sq ft semi-custom homes with a density of 30-100 units per tract. DR Horton eventually moved into the multi-family market and Jason began building large scale sites with single, 2 and 3 story condominium products with multi-family sites ranging from 90 to 750 units. In 2004, Jason was promoted to Project Manager at DR Horton, where his duties consisted of the overall buy-out and bidding of multiple multi-family projects including subcontractor selection and contract negotiation, building of DR Horton construction teams and value engineering all aspects of construction.

In February of 2009 Jason joined Fortress General Contracting as Vice President of Operations to oversee all field operations and construction personnel.

During his 20 years in the construction industry, Jason has obtained certification from the IBEW.  Jason is Dust Control and OSHA certified in addition to receiving his Superintendent Certification from the National Home Builders Association.

Jason has lived in the West Valley for 36 years and currently resides in Peoria with his wife, 13 yr old son and 10 year old daughter.  Having lived and worked in the Valley for almost 40 years, Jason has a strong sense of pride in Arizona and our local community.
