client testimonials

"In a short 6 months, I went from disorganized, struggling to respond to my clients, not properly marketing my products, to having professional product reviews posted on a weekly bases which boosted my product sales by 50%, my clients were very pleased to have immediate responses and with that being addressed, my books were ultimately fixed as well."

- lisa g., Q+A with SJ // SJ's Beauty Bar

"One thing I truly appreciated about her services is that she not only boosted my business, but she kept me accountable for things I needed to hold up on my end to keep the business thriving. I cannot thank her enough for not only turning my business around, but being a fantastic mentor, a listening ear, and more importantly, someone I call my friend."

- lisa g., Q+A with SJ // SJ's Beauty Bar

"When my first new client fills out the day-of proposal and I did not lift ONE finger for this $1000+ invoice to be created & paid.
