Vickie” Ortiz, CMA

Primary Role: Medical Assistant to Scott Mack M.D., Office Manager

Vickie has worked in the practice of OB/GYN for 20 years. After Dr. Del Riego sold his practice to Dr. Mack in 1998, she stayed on as his right-hand person right up to the date!

She has extensive experience and an impressive knowledge base of patient education in all areas of OB/GYN office practice. Her early education took place in her native country of Nicaragua – thus she speaks Spanish impeccably.
