Grzegorz Wenc, MBA
Grzegorz Wenc was born in Tarnów, Poland but immigrated to the United States at a young age with his parents and sister. He was raised in Rhode Island and now resides in Massachusetts with his loving wife, Jaclyn, and their dogs. He received his undergrad and MBA degree from Johnson & Wales in Providence, Rhode Island. It’s a testament to his drive and dedication that, although he had the option to complete his undergraduate studies early, Grzeg chose to take an additional eight courses in order to obtain a concentration in forensic.
Grzeg started his career with KPMG and has been with McLaren & Associates since 2015. With his notable accounting skills and attention to detail, he has become an excellent addition to the firm’s specialty: strategic tax planning and forensic accounting. What does he like about working at M&A? “The people that I work with, the environment, and the clients. I like how we don’t just input data into tax software to prepare a return. Instead, we provide actual advice that saves the client money. We become their trusted advisor and play a role in their business and their lives. You feel like you are a part of their success”.
Outside of work Grzeg likes to watch sports and spend time with his family and their extended family. A fun fact about Grzeg is that he is a huge American football fan. When his nephews were younger, he took them to their first professional game. It was a Patriots home game versus the Bengals. They had such a fun time that they have made it a yearly tradition. Once his nephews became a little bit older, they started going to away games. Their goal is to see the Pats play in every stadium in the NFL!
Grzeg admires and gives thanks to his parents for shaping him into the person he is today. His dad has a military background, and his mom is college-educated and had a great career working for the government in Poland. His parents gave up their careers when immigrating to the U.S. and became blue-collar workers for reasons that America represented an opportunity for a better way of life for his sister and himself. Grzeg will always be grateful for their sacrifice and will never forget it. Grzeg is happy to say that he is “living the American Dream” and his parents played a major role in that. His mom showed him the softer side of life such as caring for people, doing the right thing, and staying positive. His dad instilled discipline in him and taught him how to be mentally strong. He showed him the importance of family and how valuable it is to have a strong work ethic as he had worked over 50 plus hours a week for as long as Grzeg can remember. Family life was not always easy growing up, there were some hardships, but Grzeg always had the support of his family. “They were always there for me as I am for them”.
Jennifer Chase-Williams, CPA, MBA
With over 30 years of experience, Jennifer Williams is the firm’s strong right arm, bringing to the table a profound understanding of tax issues—especially those concerning the ramifications of stock options and other employee incentive programs. Her depth of experience and selfless dedication has proved invaluable to the firm and its clients.
Jennifer was born and raised in Worcester, MA and now resides in Hubbardston, MA with her hockey-loving family. She has had an array of influential mentors over the years, but recalls one in particular, “I had a boss who sent me back to get my MBA and my CPA knowing full well that I would end up leaving after my education was done.” That being said, Jennifer graduated with her bachelor’s from New York University, received her MBA from Clark University, and was invited into the Beta Gamma Sigma Society, the international honor society serving business programs accredited by AACSB International (The Association to Advance Collegiate Schools of Business).
When she served as then Loan Specialist and Director, Jen exemplified The Center for Women and Enterprise’s mission “to empower women to become self-sufficient and prosperous through Entrepreneurship.” She helped many of the Center’s clients develop business plans and secure funding for their businesses. “I love being in service to entrepreneurs and their growing companies,” she says, which is clear in her consultations with clients regarding the tax implications of their business decisions, and in her work as a former instructor at Clark University where students learned about taxation, entrepreneurship, accounting, and financial analysis.
Owning and managing five-day care centers in Central Massachusetts gave Jennifer firsthand experience in running a business, and she enthusiastically shares the lessons learned. Taking a hands-on approach to clients’ needs, she works with the McLaren and Associates team to uncover options that other CPA’s miss. Clients say this not only reduces their taxes, but it also helps them to better run their businesses.
Jen is a member of the AICPA, MSCPA, Provisors, and Business Networking International. She is also a winner of the Worcester Business Journal’s “40 Under Forty” award and a lifetime member of the Abigail Adams Society (she’s even portrayed Abigail Adams in “1776” on stage at Theatre at the Mount!) She also was accepted published an article through MassCPAs for reducing stress “Finding Balance: 10 Tips for Managing Stress and Enjoying Life” (Spring 2025)
While most important to Jen is her family—she is devoted to husband Jeff and sons Emery Chase Markles and Gordon Nathaniel Williams—she takes seriously her commitment to others. “I love our team here at McLaren & Associates, and I’m proud of our dedication to helping our clients. I need to be in service, and at McLaren & Associates I can do that by providing extraordinary forensic and strategic tax services.”
Jennifer finds support, inspiration, and encouragement through one of her role models, Cherie Hafford. “My coach, she has such a clear inner voice that tells her the right answers. My inner voice is more of a whisper at this juncture, but I am working at it!”
Although very accomplished already, Jen would like to receive her MST someday.
When Jen is not at work, she is singing opera. She also loves watching her son and the Boston Bruins play hockey and spending time with her grandson.
Guilty pleasure? “I like watching episodes of the original Law and Order” but she also confesses she likes “Our fourth of July ritual: Watching the movie of 1776 (with William Daniels, Blythe Danner, and Ken Howard) and crying like a baby at the sheer beauty of this piece of theater and its portrayal of the struggles and compromises endured to gain our freedom from Great Britain.”
Patrick Sweeney
Patrick Sweeney was born and raised in Northbridge, Massachusetts. He is a first-generation college graduate.

He is now pursuing his Master of Science in Management with a concentration in Accounting.
Patrick has three older half-siblings who are 8, 10, and 12 years older than him. This pushed him to grow and mature faster than most and allowed him to connect well with people who are older than him.
When Patrick is not in the office he is at the gym, playing golf, out with friends, or hiking with his blue nose Pitbull. On the weekends he likes to go to his family’s summer home in Connecticut. Patrick loves cookouts and is a master spike ball and cornhole player.
Patrick started working at McLaren & Associates in 2020. What does Patrick like about working at M&A? “What makes M&A stand out is the culture that has been created over the years. After interning at a previous firm, I can really see the difference at M&A because we are always trying to improve, and by us improving, we are able to communicate and service our clients’ needs that much better.”
Patrick would love to travel and see the world with his friends and family. He hopes to earn his CPA and own his own business one day.

Having a team that collaborates well to balance work and relationships makes all the difference when going to work every day.”

The perfect weekend for Julia would include sleeping in, visiting her favorite café, hiking to feed the local turtles, attending a car show, playing games, spending time with her friends and family at the drag strip, a day at the beach or maybe spending the day in with her two Siamese cats and northeastern painted turtle.
Vartika Jain

In this position, I specialize in maintaining accurate financial records, reconciling accounts, and managing payroll. I take pride in delivering precise financial insights that support informed decision-making for clients and stakeholders.
What I value most about M&A is its collaborative culture, high standards of work, and opportunities for continuous growth. These qualities inspire me to contribute my best every day and to grow as a professional.
Outside of work, I enjoy painting, traveling to explore new cultures and landscapes, and practicing meditation to maintain mindfulness and balance in my life. These hobbies fuel my creativity and provide fresh perspectives that I bring into my professional endeavors.

Lisa M. McLaren
When it comes to dedication, energy, and drive, the apple doesn’t fall very far from the tree in the McLaren family. Daughter Lisa was born in Worcester and raised in Millbury, MA. Her earliest memories are of family, building a snowman with Dad, apple-picking with her maternal grandmother, going to the carnival. “Family and friends – they’re still the ones who make me laugh.”
Lisa is a full time Registered Nurse and has carried her love of family and close relationships into her work environments. She works part time at McLaren & Associates doing a variety of administrative duties. “I love the atmosphere here. It’s a family feeling. Clients attend family parties, they feel that close! I never feel reluctant to get to work. We all try to be as communicative and open as possible – it’s a very positive environment.”
Lisa’s commitment to serving others extends beyond the McLaren & Associates offices: She is currently employed as a full-time Registered Nurse, she’s worked as an Emergency Medical Technician (EMT) for several years while earning her bachelor’s degree in Pre-Medical and Health Studies from the Massachusetts College of Pharmacy and Health Sciences in Boston, with a concentration in Health Psychology. “I feel that this job at McLaren & Associates plays a supplementary role in helping me to become a better healthcare provider. Healthcare is ultimately a business, and I didn’t realize that until I was halfway through college. I now feel I can develop a more in-depth understanding of the healthcare field from observing my father and his clients, and how they run their own businesses.”
When she’s not at the hospital or at the office Lisa directs her considerable energy into kickboxing and Krav Maga, a self-defense system developed by the Israel Defense forces (“I’ve got a yellow belt!”) and the sea – Old Orchard Beach in Maine often beckons.
Guilty pleasure? “Reality TV – it’s awful, but entertaining.”
