As we continue to expand, we’re looking for a talented Senior Tax Associate to bring their expertise and leadership to our team.

• Modern tax software and systems, updated as needs evolve
• A culture of continuous learning, mentorship, and professional growth
• Meaningful client relationships with high-net-worth individuals

• Medical and dental insurance Health Reimbursement Arrangement
• Long term disability and life insurance
• Commuter benefits for hybrid and in-office positions
