Staff Profiles

Shawna M. Howe, CPA

As the daughter of an entrepreneur and helping to manage her husband’s small business for 25 years, Shawna understands the concerns and challenges that exist for the self-employed.  She has used this understanding to aid her clients in ways that few CPA’s can.  Her vast experience with Quickbooks software consulting, payroll, and employee benefits allow her to assist clients so they can focus on what makes them money.

She joined Holmstead & Hyatt, a CPA firm in Twin Falls, Idaho in 1994. Her initiative, work ethic, and client focus at her job, and with the encouragement of the partner group, led her back to school. 

Shawna graduated from Boise State University with a Bachelors Degree in Accounting in 2005 and shortly thereafter received her CPA designation.

Shawna’s experience with the medical field began when she took a job with Magic Valley Regional Medical Center in their payroll and accounting department.  Upon returning to the accounting firm, then called HCM Holmstead, she continued her focus on medical provider accounting.  She was promoted to the position of Tax Manager and was responsible for quality control and review of corporate, partnership, limited liability companies and individual tax returns and financial statements.

In October of 2011, Shawna joined longtime partner Mark Holmstead to form Holmstead Howe, PLLC as a full partner.  They have been able to leverage their energy and skills to provide a haven for small business serving a wide variety of clients in farming, ranching, medical firms and main street professionals.

Shawna has served as a member of the YMCA Board, Magic Valley Marlins Board, Chamber Finance Committee and President of the Magic Valley Traders Club.  When not wrangling the office Shawna can be found nestled in a book or held up at a cabin surrounded by family.


Jared Calvin Heward, CPA, CVA

Jared gained a great love and understanding of small business and agriculture growing up on the family farm in Burley, Idaho. This upbringing has shaped his life and helped him to better serve and assist his clients.

Jared graduated from Idaho State University with a Bachelors Degree in Accounting in 2006 and later graduated from Boise State University with a Masters Degree in Accounting-Taxation in 2007.

Following school, he joined the certified public accounting firm Cooper Norman, of Twin Falls, Idaho. After passing the CPA exam and gaining necessary experience in the accounting arena, Jared determined to increase his knowledge and skillset by accepting a financial underwriting position with Rabo AgriFinance.  This experience in the Ag lending environment proved to be vital as Jared learned the evaluation process by which his customers are scrutinized. In addition, Jared gained valuable connections and lifelong friends from his time at Rabo AgriFinance.

In 2014, Jared joined Holmstead Howe, PLLC in an effort to better serve his friends and neighbors in agriculture and small business.  The following January of 2015 he was admitted as a partner. Jared assists clients in the areas of taxation, financial statement preparation, business valuation, business consultation, and litigation support. His experience has led him to focus on farm and ranch accounting and small business.

In addition to his CPA designation, Jared also holds the professional designation of Certified Valuation Analyst.  This designation allows him to prepare business valuation reports and the experience has enhanced his business analysis and planning skills.

Jared has dedicated time to serve on the Family Health Services Board, as President of the Business Networking International, Chamber Ag Committee and had many adventures with Boy Scouts of America.   When away from the office Jared is often traversing down a river or tramping through the woods with family and friends.


Robert D. Thurston, CPA (Of Council)

Bob grew up on a small farm in Springfield, Idaho just big enough to keep 4 boys busy and mostly out of trouble. As one of these first four boys of 7 total children, Bob became very close with his brothers. So when his elder brother encouraged him to pursue a career in accounting, Bob followed the advice.

He then discovered a natural aptitude for his accounting courses and his field of study was set. Bob later graduated from Brigham Young University with a Bachelors Degree in Accounting in 1973.

Hired as an auditor, Bob began work for the CPA firm Hurdman Cranston of San Francisco, CA.  While in California, Bob met and married Miss Margie Brooke of the East Bay area. The knowledge and skills gained working in California later helped him secure a position as an auditor and move closer to home with the firm Peterson, Seamon, Stacey, and Bancroft of TwinFalls, Idaho in 1977. It was at this time Bob was introduced to the rigors of tax preparation and, as before, he demonstrated a great capacity to understand and benefit his clients. In July 1989, Bob ventured out on his own to form Thurston Financial Services, Inc.

Bob enjoys the relationships made through assisting and offering tax planning and financial advisory services. He has over 40 years of experience with corporate, partnership, Limited Liability Company and individual income tax. His focus has been farming, ranching, construction, professional services and many other small business owners. He is a firm believer that anyone can prepare a tax return but individuals and businesses come for the value added, the alternatives, and a plan.

In January 2013, Bob joined his talents with Holmstead Howe, PLLC. This move has allowed Bob to focus more on the needs of his clients and family and less on the administrative demands of managing the accounting practice. It has also enhanced the knowledge base and skillset available to the firm’s other clients.

Bob has given back to the community through coaching little league sports and his extensive involvement in Boy Scouts of America as a District Commissioner and Council Treasurer. For his service he was awarded the distinguished SilverBeaver award. When not in the office you can often find Bob working away quiet hours in his yard and gardens or catching up with his bride of nearly 40 years and their 4 children.

In 1988, Mark started an independent accounting firm to better serve his client’s needs. Several years later Mark partnered with Brent Hyatt to establish the Holmstead & Hyatt, CPA firm.

Managing his own accounting firm has given Mark exposure to tax preparation and business consulting for a wide variety of clients including partnerships, corporations, and limited liability companies. He also gained experience with farming, ranching, medical firms, commodity warehouses, and many other small businesses in helping them to navigate the complexities of the tax law.

As part of this experience Mark has proven to be an effective representative for clients to bring about positive resolution in matters with the Internal Revenue Service and the Idaho State Tax Commission.

Mark has set himself apart in his understanding within the trust and estate arena. He keeps current and continues to perform estate planning along with the detailed preparation of estate and trust tax returns. He has received his Certified Valuation Analyst designation. This has allowed him to be involved in litigation support for divorces, business disputes, and business valuation. Mark has been appointed receiver and agent by the courts to facilitate litigation matters.

In October of 2011, Mark formed Holmstead Howe, PLLC with Shawna Howe in an effort to better service their customers.
