"My name is Martin J. Michael, and I am the President/Founder and Pastor of Shalom Christian Prayer Fellowship Inc., New Jersey, USA. An International non-profit organization that engages in global outreach and evangelism. Our outreach extends to countries like Kenya, Uganda (Africa), Pakistan, India, Peru, Ecuador, Nepal, Costa Rica, Etc.

With enthusiasm and pleasure, I am writing this review for Mr. Christopher Arun Kumar, a professional who demonstrated high-level professionalism, dedication and expertise.

I approached Mr. Christopher Arun Kumar in 2018 to register for incorporation of our Church with the state and file 501 (C ) (3) tax Exemption for our non-profit organization.

His professionalism, tenacity and dedication have made a lasting impression on the Shalom Christian Prayer Fellowship community. He guided us step by step throughout whole process and what impressed me the most was when I told him that we are a small home-based Church and are very limited in our resourced, He told us not to worry about it and helped us out beyond our expectations. Mr. Christopher also got the job done on record time and we are very grateful for his services."

We highly recommend them and will continue on as dedicated and very happy customers."

"I recently moved to the Frederick, MD area and a friend recommended Chris to me to handle my personal taxes. After my initial consultation, I knew Chris would be perfect. He takes the time to get to know you, is professional and thorough, and once I provided him the information he needed, he was able to turn around my returns in a short time during this very busy tax season. I highly recommend Chris and will be a return customer for sure."

"What can I say about Chris,
His abilities, knowledge and experience and his warrior like attitude to attack a problem and find a solution. He’s definitely a driving force in his field.
I met Chris in the martial arts, where we nicknamed him Rhino.
That is because he puts his head down walks a straight line and attack the problem.
Both in his profession and in life.

One of the main qualities I like the most about Chris, besides his skills in getting the job done.
Is he trustworthy, honest and always stands by you. Hard to find these days.👊"

"Thank you Chris for your quick and attentive help in filing taxes for me and my husband. We were struggling to file taxes on our own because our situation is more complex and our previous accountant had left the practice without telling us. You made our experience very smooth and relieved us of a lot of stress. We appreciate your care and patience in serving us."

"I used Cornerstone Accounting Services to prepare my 2025 Federal and State tax returns, and they did a fabulous job!

I retired last year and withdrew a large sum from my investment account. This action caused an impact on my Federal and State tax returns' financial responsibility. Mr. Arunkumar, the accountant I worked with at Cornerstone Accounting Services, was extremely knowledgeable in explaining the impact on my tax returns. He also addressed my questions, and his responses were easy to understand. Additionally, he responded promptly to my emails and phone calls during the preparation process. Once my tax returns were prepared, I was pleasantly surprised to learn that the amount owed was less than I expected.

A friend referred me to a person whom I paid to prepare my 2024 tax returns. During the preparation of my 2025 tax returns, Mr. Arunkumar, also reviewed my 2024 tax returns and found errors. He recommended that an amended tax return be filed for tax year 2024. Therefore, I authorized him to prepare an amended tax return for that year as well. I realized that using Cornerstone Accounting Services was a great decision. Using a company with proven tax expertise was invaluable.

Working with Cornerstone Accounting Services was a true blessing! I will use their services again. I highly recommend this company!"

"We are happy to have found Cornerstone Accounting Services for our Business and Personal taxes. They have been professional and helpful with timely responses to questions as well as educating us as we transition from another firm. Highly recommend."

"It's been a great experience working with Chris. He offered professional and knowledgable tax planning for my individual and business taxes. He explains every step clearly and connects you with who you need know. Thanks, Chris!"

"Chris with Cornerstone Accounting is the consummate professional who goes above and beyond for his clients. After a poor experience with a large, expensive accounting firm, my trust in accountants and tax professionals was shot- Chris’s personal service, patience, thorough attention to detail, and sound advice makes him the perfect fit for my small business. I’m grateful to have been introduced to him!"
