Yes, Marianne Alef! When I know I’m getting transferred to Marianne I get excited. She is knowledgeable and helpful in a welcoming way that makes me feel respected and appreciated. I have come up with needing back certificates, scheduling for a out of spec scale needing immediate service. Marianne has been there to get us out of our challenges and she doesn’t mind if I get a few giggles in from time to time.
