About Us

Two Small Business Owners.
Two Different Career Paths.
One Great Team.

Rita Crosby


Like any good dance partner, Rita’s business experience has been filled with intriguing steps, spins, and graceful moves. Two years after graduating from NIU with a degree in Journalism-Advertising, at age 38, she started her first business, a small advertising business, in the low country of South Carolina.

She sold the business when the family moved to Houston. There she assisted a major Woman-Owned business as the liaison with corporate diversity partners, planning trade shows, and training sales people. She conducted business classes for UH/SBDC. When her son went off to college, she fulfilled a lifetime goal and became a national and international speaker. She is considered a Subject Matter Expert (SME) in the following areas: Business Feasibility Plans, Business Plans, Marketing Plans, Strategic Planning, Leadership Skills for Managers, Personnel Law for Managers, Communication Skills, Team Communication Skills, Customer Service Training, Time Management Training,
Presentation Skills, and Leadership Development.

After moving to the Atlanta area, she became a Vistage Chair and worked with business owners in the $1 Million to $3 Million range. She left Vistage in 2009 to help small business owners under $1 Million survive the downturn, bottom, and recovery from the Great Recession by helping them learn how to use their financials to make strategic business decisions. She has facilitated Ritamac CEO Peer Based Advisory Groups for over 13 years.

Mark Crosby

Lead Facilitator

Like many small business owners, Mark had a dream of having his own business. He bought his first house at age 20, did all the work himself to increase its size by 800 square feet, and it’s value by enough to borrow the money to buy his European Auto Repair Shop, where he has been in business for 37 years.

In almost four decades there have been numerous employees, thousands of customers, two major recessions, good years, and difficult years. The industry and skills have changed dramatically. Mark understands what it takes to survive as a small business owner.

Mark has also participated in, and helped run with great success, numerous service groups and charitable events. And to add to his substantial business knowledge, he recently completed an extensive, high level mastermind group facilitation class and is ready to help other small business owners achieve success in today’s challenging business environment. He views the Ritamac groups as a seasoned cabinet of business men & women banding together to tackle each other’s problems and issues in an intelligent, respectful and fully confidential manner.

The mission of Ritamac, Inc. is to provide the platform and environment for owners of businesses $1Million and under to develop the skills and strategies needed to create their vision of success.

Our purpose is to make a positive difference in the lives of small business owners and so to their employees, clients, families and communities.

We’d love to know the story of your business.
This is our story:

We met in July 2019 through dance. We both had taken ballroom dance classes from the same instructor for several years, before being introduced as potential dance partners. We quickly became friends, fell in love, and were married in September 2020 in a ‘Covid Wedding’. We had to limit in- person guests (10) but were able to share our ceremony, dance, and celebration via Zoom with over 200 guests in 15 states.
We love living in San Diego, and enjoy working, playing (hiking, sailing) and dancing together.

In January 2022, we decided it would be great to bring Mark’s 37 years of business ownership experience into Ritamac. Together we are your perfect team for finding success with your business during these changing times!
We look forward to talking with you.

What People Are Saying

As a CEO it is great to have another impartial set of eyes looking over your shoulder and holding you accountable. I always leave our meetings with new ideas on how to improve the performance of my company.

Bill Adams

Adams Realtors - Atlanta, GA

I’m not sure I would still be in business without Rita. She taught me how to think strategically as well as how to analyze the health of my business. Meeting monthly with our group has been very helpful. I am always learning new skills and meeting challenges that affect all businesses. Running a business is not easy. Having Rita and a group of peers to help has made all the difference for me!

David Kurkoski

Aesthetic Solutions Inc. - Atlanta, GA

As a business coach and facilitator Rita is a rare gem in the field as she has a unique understanding about supporting my goals of building a successful “values-based” business. She has done an excellent job of clarifying my business’s mission and purpose as well as helping me assemble my team of experts and advisors.
