Erika was the office manager for LGA for almost 11 years, from the early days in 2008 to early 2019. She was the face (and sense of humor) of our front office and provided invaluable help to the practice through all those years. She is no longer working in the office on a regular basis but she does come in periodically to help Dr. Stevens out with lots of managerial tasks. She continues to be an important part of LGA even though we don't get to see her very often anymore.
Macallan "Mackie" Stevens
Macallan joined the LGA staff in late April 2017. She doesn't provide on-site services very often, but occasionally does rounds after hours or on weekends. She has a serious interest in security and property management, enthusiastically expressing her philosophy to mail carriers and other delivery personnel. In her spare time, she enjoys bird watching, cat herding and tossing squeak toys. She's shy at first, but she's likely to treat familiar visitors to an impromptu tap dance or merengue.
Deputy Security Officer
Alaina joined the LGA staff in early April 2018. She works side by side with Macallan and though they are not often on site together, she is diligent about security and property management. She tirelessly fends off incursions from birds, squirrels, chipmunks and falling oak leaves. In her spare time, she enjoys playing with her sister, stealing shoes, chasing cats and singing like Ethel Merman.
Director of Security, Emeritus
With great sadness we want to let our patients and friends know that Theodore passed away in late February 2017. He met and snuggled with many of you and always enjoyed his time here at work. He was a beloved member of our LGA family and we miss him dearly.
Director of Human and Canine Resources
Piper is a versatile member of the LGA staff. A young and energetic worker, she originally specialized in redecorating and light housekeeping, but quickly demonstrated her talent for managing human and canine staff members. She currently works from home but plans to incorporate site visits into her schedule in the near future. She has an interest in security and will likely involve herself in protecting the staff and surroundings. She feels that a work station near Dairy Queen should allow her to adequately monitor the activities around the office.
