Those who know Dmitriy Matushevskiy well today will attest that he is not a hard person to read. His values and priorities were carved into his character since childhood. Born in the Ukraine during a period of extreme religious persecution, his grandparents and eventually his parents were lured to the United States by the desire for freedom and opportunity. Dmitriy is inspired by the memories of what his family endured. “I remember the sacrifices and difficult times my family endured in Ukraine and continue to be motivated by their courage and resourcefulness.”
After arriving in America in 2001 as a teenager, Dmitriy was drawn to the construction trade but lacked the knowledge and expertise he needed. He was hired by two contractors to help install windows and other small projects. In both cases, these people refused to pay him. But he didn’t let that disappointment sour him on construction. He knew then that it was how he wanted to spend his life. He found another contractor he trusted and offered to work for free if he would teach Dmitriy the trades. That arrangement lasted for two years and inspired a 17-year-old Dmitriy to make an offer on his first piece property in Sacramento for $25,000. He wasn’t discouraged by the fact that he didn’t have any money and spoke only broken English.
What he lacked in money and articulation, he made up for with the kind of determination and resourcefulness he had learned from his family. Dmitriy recalls, “I was young and naïve with little appreciation for the very long odds I faced. I found the property owner in Florida and convinced him to do a below-market deal. He agreed and then I was faced with the reality that I had no money to buy this property. I made up my mind that I was going to find the money no matter what and somehow, I did.” He built a duplex and sold it for a nice profit. Dmitriy was thankful for those who helped him get his start and was humbled by the good fortune that he fully attributes to divine intervention. He was so grateful, that he donated his six-figure profit to his church. “Too many unlikely events went my way that allowed that experience to bless my life. I felt compelled by my faith and the years of blessings my family enjoyed through our church community. It was the right decision.”
The crash of the real estate market in 2008 took its toll on the construction industry and Dmitriy was no exception. He was so devastated by the setback, he struggled for many months to find his next career move. He tried a few uninspiring things outside of construction and in 2010 divine intervention struck again. Dmitriy found an opportunity to do property preservation and realized this was his chance to get back into the construction game. He has been talking to his friend Sergey at church and found out that he also had an industry background. They agreed to become partners in a property preservation company which became successful and broadened the construction expertise of both men.
As the economy improved, Dmitriy dove head-first into flipping houses in Florida and new construction in California. In 2017, Dmitriy and Sergey began discussing a shared vision of creating a different kind of company that would help homeowners make improvements without the stress, dishonesty, and broken promises experienced by many. Along with another Church friend Vazgen (Vaz), Cobex was born. Dmitriy remembers, “From the first conversation, it was clear that the three of us shared the same values, vision, and goals for our new company. We committed to each other then and there to stay true to those principles.”
Dmitriy recognizes that his determination, high standards, and attention to detail lead him to be single-minded about work, even during traditional off hours. But he vows to work on that. “My wife Angelica and I have two young sons and a baby daughter. They are a loving reminder that there is more to life than work. I don’t have a lot of hobbies or outside interests but spending time with them makes me realize what is really important.”
Dmitriy reflects on his accomplishments. “My partners and I feel fortunate that we have a company focused on family. It is very rewarding to create jobs and career advancement opportunities for our family members and devoted team members. Cobex is a place where people can enjoy their work, feel
appreciated, and embrace professional development. When a customer gives us a positive review, we all share in the moment. As owners, we are mindful of how blessed we are and devoted to sharing those blessings with others.”
Vazgen Dallakyan is the co-founder and CEO at Cobex. For the past 6 years, Vazgen has worked on business development for Cobex from Sales and Marketing to technology and operations.
Vazgen is recognized for his innovation in marketing and technology implementation for Cobex.
He is an Alumni graduate of Sacramento State College where he earned his Bachelors in Kinesiology and exercise science. In his spare time, Vazgen enjoys spending time with his 3 young children and wife, traveling, and creating new experiences together.
