Meet Our Advisor Team

All top-tier MBAs with professional writing and coaching in their background as well as determination as they withstood being trained by Kathryn who is unapologetically ruthless, our advisors give their all to help clients realize their business school dreams. To ensure they're able to give their all to clients, they work with no more than 6 clients at a time; many work with only 1-3. Our advisors are why our success rate is what it is.


With former top business school Career Management members as well as an award-winning author who was formally trained at Harvard and USC to build his creative writing chops, our leadership team can't imagine a more rewarding way to spend their days (and often nights) than providing clients the support they need to move from square one to business school. They too are why our success rate is what it is.

Kathryn Lucas, Founder

In 2009 Kathryn Lucas founded Square One Prep, an MBA Admissions firm that has partnered with 900+ clients and sustained a success rate that no other firm matches.

With a Bachelor of Architecture degree from Auburn University, after which she practiced architecture for seven years, and an MBA from Wharton, Kathryn ventured into MBA Admissions in early 2003 when she became a GMAT preparation consultant at Veritas Prep. Later that year, she joined the commercial development team at Forest City Ratner to help manage the development of Atlantic Yards/Barclays Center, a $4 billion, 7 million square foot, Brooklyn-based project designed by Frank Gehry. She dedicated herself to that endeavor until June 2007, when she left the world of development to write a book, It Is What It Is, published in July 2008. Inspired by how her book motivated people to introspect, face challenges, and dream big, she then re-joined Veritas Prep as an MBA admissions advisor so she could continue to help people assess their lives and reach for their ambitions. Not long after, realizing that her approach to partnering with applicants was distinct and unusually successful, she started Square One.

Kathryn’s approach involves providing expert, hands-on advice with wit and candor, thereby making the notoriously grueling application process enjoyable for clients. She's also ruthless and trains her team to be equally supportive and relentless in their effort to guide their clients to craft customized, authentic applications that make the admissions committees feel something and want to know more.

In addition to being involved in all PREMIUM partnerships (we have two services: PREMIUM and PREMIUM NEED-BASED), Kathryn also conducts 100% of the firm's free consults. She'll tell you what she believes the truth is, based on her empirical data and experience. Sometimes what she says will align with what you want to hear (and you'll think she's amazing!), while at other times what she says may lead you to want to throw your phone and end the call! But you can trust that she is trying to offer you supportive candor.

With expertise in creative writing, academic coaching, and marketing, Kathryn has personally guided 220 clients, with a success rate of 97%. Simply put, she loves helping folks make their aspirations come true.

Kathryn is also a member of AIGAC (Association of International Graduate Admissions Consultants). When she isn’t busy helping her clients manifest their career dreams, she enjoys practicing yoga, traveling, dancing, trying to learn French, training for half-marathons, and exploring artists in the electronic music space.

Samuel Johnson, Lead Editor

Samuel Johnson, Square One Prep’s Lead Editor, is an award-winning writer and producer who has been working with writers to help make their writing pop since he ran his high school comedy magazine… Working alongside Kathryn, he uses his creativity, sense of humor and eye for detail to review every piece of Square One Prep client writing to ensure it shines the best light on clients’ applications and sets them apart from the pack.

Samuel graduated from Harvard in 2007 with a degree in Russian Literature—his favorite authors are still the Russian greats—and from the feature film producing MFA Program at USC in 2009. While at Harvard, Samuel was a writer and editor of the longest-running comedy magazine in the world, the Harvard Lampoon, for four years and became its Vice President his senior year. He also wrote and produced a musical comedy as part of Harvard’s “Arts First” Festival. At USC, Samuel was awarded the Jack Oakie scholarship for excellence in comedy screenwriting and a second-year production grant for a short film he wrote.

Since graduating, Samuel’s writing has appeared in the Huffington Post and Nat. Brut as well as on Cartoon Network and Pixl TV. He continues to write screenplays which have been selected by such organizations as the Cinestory Foundation Fellowship, the WeScreenplay screenplay competition, the StoryPros screenplay competition, and Shriekfest Film Festival.

For the last eight years, Sam has worked with students applying to MBA and other graduate programs to craft the most compelling essays possible. He approaches each student as a unique individual—as there is no cookie-cutter method of writing a winning MBA essay! He has read and edited thousands of essays.

Samuel speaks French, Mandarin and Russian and will talk your ear off about movies if you let him.

He loves learning from and educating his clients, all of which occurs due to the tough questions he asks that lead clients to do research, introspect, and come back to discussions having learned more about themselves and what they do or don’t want to do.
