Helping business owners understand their numbers all year long with tailored accounting solutions, effective bookkeeping, and guidance from a Certified Public Accountant for efficient tax planning and tax preparation.

Originally from Egypt, Oasis Heritage's owner Mohammed Hassan built his life on the values of hard work, integrity, and service to others. Those values have guided him every step of the way — from starting a new chapter in America to putting down roots in Hampden, Maine, where he now lives with his wife and their three children.
As a husband, father, and business owner, he understands the importance of creating stability, planning for the future, and making wise financial decisions. This understanding is at the heart of his CPA practice, where he offers comprehensive accounting solutions. What began as a vision to serve families, individuals, and business owners has grown into a flourishing firm dedicated to helping clients navigate tax preparation, bookkeeping, and financial matters with clarity and confidence.
While his firm proudly serves the local Maine community, its reach extends far beyond state lines. Today, he works with clients not only across Maine but throughout the United States, offering trusted CPA services with a personal touch. No matter where a client is located, they receive the same commitment, care, and attention to detail that have become the foundation of the business. At its core, the business is about more than numbers. It is about helping people feel confident, informed, and supported as they make important financial decisions. Whether serving a local family in Maine or a business owner in another state, he is committed to delivering trusted guidance in tax planning and bookkeeping with integrity, precision, and heart.
