“I saw the progression and deterioration that the disease caused the physical body, and I wanted the opportunity to work with clients who are struggling with addiction before the damage is irreversible. The stakes are high. Just like other chronic diseases, it’s a life or death situation, and when one is facing something that may be terminal, the whole family suffers”.

She is dedicated to offering exceptional service to clients and believes in continuous quality improvement, client safety, and privacy, and creating an environment that promotes physical and emotional well-being.

She is committed to hiring exceptional employees who are passionate and dedicated to helping people recover from addiction.

“It is an honor to be placed in a time and space where someone may very well be at their worst and to be able to have the opportunity to make a difference in someone’s life. I try to remind my staff of this in everything we do each day because you never know the impact that you can make on others when your heart is open to it”.
