A consummate professional with decades of strategic insight

When our healthcare organization faced a complex regulatory investigation, we turned to Terese Beluris. Her 43 years of experience, particularly in health care law and administrative proceedings, were immediately evident. She guided us through the litigation with a steady hand, combining her deep knowledge from Loyola Marymount with practical, strategic thinking. Terese’s recognition in both health care and commercial litigation is well-deserved. Her team at Buchalter was exceptional, but it was Terese’s personal oversight that ensured a favorable resolution. She is not just a lawyer; she is a trusted advisor who understands the stakes and delivers results.
