Meet the Team

Executive Staff

I started in this industry in 1978 back in Michigan cleaning carpets, then went into a school district and worked my way up through the ranks to over see the cleaning and maintenance of an elementary school. Moved out to Northern California in 1985 where I accepted a position with a national commercial cleaning company and supervised the night operations. Then accepted a position with a window cleaning company in 1990 as their vice president of marketing. In 1991 I started a window cleaning company along with a business partner and grew that company then sold it in 1992. From there, I accepted a position with one of the largest national cleaning companies. I worked my way up to their regional manager. In 2002 I decided to venture out again-but on my own this time. My new company, United Building Maintenance, turned into a multi million-dollar company after it’s 2nd year of business. First, I believe the success of the company is putting the employees first. If you have happy employees, it shows in their work and ultimately your clients are pleased as well. Second, would be placing our time in retention of our clients, not new sales. Our growth has been through word of mouth from one client to another. My role in the company is to serve each employee with what ever their need may be and to always be accessible, I am a hands on business owner but I do not micro manage! This company would not be where it is today with out the employees from the front line right up to upper management. I will always remember how we got here and I will always take care of them along the way. I want to thank our clients for their loyalty and making us part of their team.
What does it mean to me to be part of United Building Maintenance? Val and I have known each other for over thirty years and have always had a mutual respect for each other. I believe our core values align with each other’s. So when this opportunity presented itself I knew amazing things will come from this partnership.We both value our clients and our employees. I am all about building people up and creating opportunities for them to grow, learn and advance within our company.I believe that Trust, Respect, and Integrity are key core values. Everyone working for us brings value and should be recognized for their contributions. I was pleased to learn that Val has always shared her profits through her profit sharing plan with her employees; this really sealed the deal for me.I look forward to this new opportunity and the pursuit to make this already amazing company and employees the Market Leaders in this industry. By doing this it will create endless opportunities for our employees and world class service for our clients.I’ve been married for 35 years. My wife and I have two daughters and we recently became grandparents; we were blessed with twin boys. My hobbies are traveling, fishing, barbecuing on the weekends and spending as much time with our grandsons as possible.
Janice joined the United team in 2022 where she oversees the financial controls and reporting, policies and procedures as well as daily cash management and treasurer functions. She joined the United team after working with Val for many years in a consultant role because she believes the values that United models was a great fit for her. ​
If you are looking for someone who loves precise details, Alan Clark is your man. A numbers guy as far back as he can remember, Alan honed his appreciation for order and precision as a member of the U.S. Army Reserve. “My time serving in the Army Reserve reinforced the importance of discipline, taking time to manage the process, and getting every detail exactly right. If you are even a little sloppy with the small numbers, you can end up with a major mess down the road.”Alan studied animal science in college, with a business concentration. Later, he worked for startups and major international retailers, across several different industries. Alan finished his Masters in Accounting in January of 2017. Four months later, he met Val Sherman. As CFO, he manages all of United’s financial matters, from invoicing to cash flow to risk management. “As a growing company, it’s a balancing act. We have to measure each new opportunity against the bigger picture, because we are committed to providing the best possible service for all our clients.”Alan says one of the chief attractions for him was the culture of the company. “Val really cares about the company, and, by that, I mean the people on this team and about our clients. This creates a culture where honesty is expected and growth is celebrated. The people here actively support each other, and work together to help each other grow. That kind of culture is fairly rare, and we all benefit from it, especially, our customers.”At home, Alan and his wife, Jennifer, are “official empty nesters,” with four adult children busy building their own lives. “They are becoming good, productive people, and it’s so great to see. Jennifer and I stay busy too. When we’re not working or with our church family, we like to get outdoors. I grew up hunting, fishing, and hiking; so, for me, any day I can be out in a canoe with a fishing line in the water is a good day. I also do my best to maintain a good sense of humor. Yes, I know, I’m an accountant, but I also realize, if you can’t see the humor in life, you’re taking yourself way too seriously.”
Greg joined United Building Maintenance in January 2025, and immediately became an essential contributor to the values that United stands for.

To be part of United Building Maintenance is to be part of a family, and that’s exactly how I’ve felt since the day I first walked through the doors. That sense of belonging has only grown stronger since returning to the Sacramento area where my HR career began. I’ve known Brian for many years, and no matter where our careers took us, I always had a feeling I’d come back to Sacramento to work with him again. Joining United feels like the perfect culmination of that journey. I bring nearly a decade of progressive experience in Human Resources to my role as Vice President of Human Resources at United. My career is grounded in fostering organizational change and driving strategic workforce planning, with a passion for creating workplace environments that foster innovation and growth. At United, I am committed to leading impactful change initiatives that empower our employees and enhance organizational effectiveness. I thrive in environments where I can leverage my expertise in communication, workforce planning, and collaboration with management to propel our company forward. I am dedicated to contributing to a company that values innovation and embraces positive change. Working alongside a team of dedicated and passionate professionals, I am eager to achieve both strategic HR objectives and overall company goals at United Building Maintenance. Outside of work I love spending time with my family who share a passion for baseball and camping. My two boy’s play baseball takes to the diamond for softball games, time spent out on the diamond with them is time well spent in my book.
I chose to work for United because as a medium-size company, I felt I could have a higher impact on HR operations and be able to truly make a difference in the employee life cycle. So far, working at United has been a rewarding experience that has allowed me to grow as a professional and on a personal level. I have over 5 years of HR experience in small to mid-size companies and large corporations in industries including hospitality, construction and retail. In 2020, I earned my HR Certification from the Society of Human Resource Management. My area of expertise is leave administration, policy and procedure development and employment best practices. I’m originally from Long Beach, CA and moved to Sacramento after college in 2018. My hobbies include traveling, karaoke, family game night and visiting Disneyland as much as I can.

He saw it as a great opportunity because of her business acumen and the way she treated him like family and extended that same care to all employees.

Kindness, as well as a sincere desire to meet your needs, defines everything she does.A licensed cosmetologist, DeAna is definitely a people person, skills that allowed her to make a significant career change, when she joined United Building Maintenance in May of 2018. “It was different, sure, but I love it. Interacting with people, helping them however I can, is very important to me. Every day, I have the opportunity let both our clients and my coworkers know how much the company appreciates them.“Many times, I’m the first point of contact, so I have a great deal of one-on-one interaction with clients and with employees, answering questions, connecting them with the right people. A client may want to know who their account manager is, or they may want to order supplies. An employee may need to correct their time card or have a question about paperwork. When they come to me, I will have the answer or find the answer.”When she’s not hard at work finding answers, DeAna still enjoys using her cosmetology skills to help people feel beautiful, and she loves to travel and spend time with her dog, Rocky.“California has so many wonderful places to visit. The list is endless. Internationally, so far, my favorite trip was Iceland. So much to see: the glaciers, the waterfalls, the black sand beaches… What an amazing place!”

To show people a positive attitude and encourage them.” Erika says bringing that positive attitude to work with her every day is easy, because cleaning is her passion. “Even away from work, with my family and friends, someone is always asking me, ‘How do I clean this?’ or ‘How can I organize this to be more efficient?’ It’s just who I am.” Erika moved to Sacramento at the age of 15, and began her career in the janitorial and building maintenance industry in 2013, excited to turn her passion for cleaning into her vocation. She joined United Building Maintenance as a night shift supervisor and has been promoted to Night Operations Manager. “If there’s something I love more than cleaning, it’s working with people. Now, every day, I get to work with great people, building friendships and teaching them the best way to properly, efficiently and effectively care for our client properties.” Away from work, Erika loves spending time with her husband, Javier, and their two children. “I love to cook, especially Mexican food, but we like to try new things as well. I’m always looking for new recipes on YouTube. We also enjoy watching movies, going to the park or out for ice cream… honestly, we’re just happy being together, and that means everything to me.”
I have been blessed with learning opportunities throughout my work life-from experience working in the Los Angeles restaurant industry, to being a volunteer for trail construction in the Los Angeles National Forest. These solid work experiences helped me gain valuable skills in customer service as well as thriving in a team setting. For the last twelve years I was an account manager in software and telecommunications where I focused on client relationships and client satisfaction. I am excited about the opportunity to be part of the team at United Building Maintenance. My years of account management and customer service will help me lean into my new position as an account manager at United. I am a committed team player and a tireless advocate for quality service.

It means a lot when my team members come to me with their questions and concerns, because they know I’ve been where they are. They realize their safety and their ability to do their jobs well are my top priorities.” Away from work, Vianney loves traveling, especially with her kids. “I love spontaneous getaways. Just get the kids in the car, and go see what’s out there. Being able to share those experiences means a lot, because it gives us time together. No matter what we see or do, I want them to know I will always be in their corner.”
