General manager, I started working in the restoration industry on and off in 2005, and transitioned to full-time in 2015. Over the past 10 years, I’ve built my career in this field, working my way up through several roles. I began as a Water Technician, advanced to Crew Chief, then to Operations Manager, and currently serve as General Manager. From a customer standpoint, I genuinely enjoy helping people find solutions during what is often a very difficult time in their lives. Supporting insured clients through catastrophic events and helping them restore their home or business gives me a strong sense of purpose. I take great pride in educating my customers and guiding them through the insurance process, helping them regain a sense of normalcy. On the team side, what I find most rewarding is sharing my knowledge and experience. I enjoy mentoring others, helping them grow both personally and professionally, and supporting them in building a lasting career in the restoration industry.
