Kristi L. Hattig, CPA


I have over 25 years of tax experience and was a Controller and CFO for a non profit and for profit businesses that totaled over 10 years. I have done all of the accounting work from data entry to 401(k) and Cafeteria 125 implementation to meeting with insurance and workman’s compensation advisors and presentation of financial statements to owners and management. I received my CPA license over 10 years ago and have completed thousands of income tax returns ranging from individuals, trusts, S Corporation and LLC income tax returns. I have been a business owner over 13 years and enjoy personally working with the individuals, owners, investors, and/or bookkeepers of each organization. I have an extensive experience in dealership accounting and many start up businesses. I have a background in banking, in which I worked in many different components of the industry including mortgage loans.

I have three beautiful daughters, in which, two of them have been employed recently in my business. Two of my three daughters were on full ride softball scholarships, so we enjoy being active and friendly competition. I enjoy golf, biking, motor cycles, kick boxing, boot camp and crossFit. I enjoy watching/participating in many different sporting activities including the Broncos, Nuggets, and Rockies games.


Beverly Woolsey, Tax Manager

Her one desire is to help. 

Beverly moved to Boulder County in August 1991. She is married with four fur babies. During downtime, she is likely to be found somewhere with her dogs and husband. She is a passionate animal lover and avid college basketball fan. She loves being outdoors, whether it be working in her garden, hiking/biking, barbecuing or just sitting next to a pool.


Maria Vanscoy, Tax Accountant


My name is Maria de Lourdes Vanscoy. I have worked actively in accounting for the past 8 years. My experiences in public accounting include preparing tax returns for individuals, businesses, partnerships, trusts, and estates, as well as small business bookkeeping. I am originally from Ecuador where I started working in banking at an early age.

My first experience in the financial field was at a national bank and later at an international bank in the treasury department. After moving to USA and getting married, my husband and I ran an import/export business for many years; that opened a wonderful opportunity to raise our two kids.

Ten years ago, I merited my Associates in Accounting. Currently, I am working towards completing my bachelor’s degree at CSU Global. My aspiration is to continue my studies and become a CPA.

When I am not at work, I enjoy traveling, golfing, gardening, baking, knitting, arts, and crafts.


Kelly Chamberlain, Staff Accountant


I joined the Hattig CPA team in September 2019 after earning a Bachelors of Science Degree in Accounting from the University of Colorado in Colorado Springs. While I was in college, I pole vaulted for the UCCS Track and Field team on scholarship. I also worked at the Broadmoor Hotel and as a UCCS tutor for accounting students. I am currently working on my Masters Degree in Accounting at the Leeds School of Business at the University of Colorado in Boulder. I am excited to apply my accounting skills to help Hattig CPA clients with their short and long term business and personal goals. My long term goals are to become a Certified Public Accountant and work in public accounting in either taxation or auditing.


Jessica Elsey, Administrative


I was born right here in Longmont and attended Berthoud High School. After high school I moved to Yuma, Arizona where my husband of seven years, Dustin, and I had our first child Payton. We moved back to Longmont after his service for the Marines was finished. We had our second child, Ryker who is now 1 and Payton is 5.

I obtained my associates degree from Front Range Community College and graduated with my bachelor’s degree in Developmental Psychology at Post University. I have always had a passion for serving others, especially children. I have worked with my Mom, Kristi Hattig, for 4 years now, and I get to help her build her dream and be with my family along the way. It is truly a special time in our lives and I enjoy getting to serve others in a different environment, and learning new trades along the way.


Cheryl Witt, Office Manager


Being raised in New Jersey and Nebraska made for an odd combination, but moving back to Nebraska gave my family a chance to be near most of the rest of my relatives. I graduated high school in Lincoln, Nebraska, and went on to earn my Bachelor’s degree at the University of Nebraska.

The majority of my professional experience comes is in Information Technology. There I have over 20 years of experience working for large corporations in a variety of industries. As an IT Project Manager I have led large cross-functional projects with multi-million-dollar budgets, while managing many vendors, and their contracts. I have also taken time out to be a small business owner here in Longmont.

After 3 years in Texas I happily moved back to Longmont, in October 2019. I’ve known Kristi Hattig for 16 years, and I feel honored to be part of her team.
