I earned my Bachelor of Science in Education from Greenville University, where I built strong foundations in educational practices. This is my 20th year in education and my 10th year with Great Hearts. I joined Roosevelt Prep 4 years ago, and I have the privilege of teaching middle school math and supporting students during a pivotal stage in their academic growth.  My call to teaching comes from a deep desire to make a lasting impact in students’ lives, helping them develop confidence, perseverance, and a genuine love of learning. I am passionate about equipping  students with critical thinking and problem-solving skills that extend far beyond the classroom. I strive to make math meaningful and engaging, helping students see both its beauty and its real-world relevance  This year, I am excited to step into the role of Academic Dean, where I look forward to supporting both students and teachers in achieving excellence. I am eager to contribute to a strong school culture, collaborate with colleagues, and help ensure that all students are challenged, supported, and set up for success.

My name is Kelsey Nichols and I hold a Bachelor of Science in Biology from Grand Canyon University. I am so excited to share my love of Biology and the ordered universe with students. Having always been the student who asked “why” over and over and wanted to understand the details of scientific concepts or cellular processes, I look forward to exploring those answers alongside the 9th graders this year. From photosynthesis and cellular respiration to human body systems, we will answer so many “why” and “how” questions and grow in our wonder at the complexity of living things.

My name is Melissa McAllister, and I’m honored to be returning to Prep as the College Counselor. This is my sixth year at Great Hearts and my fifth year with Roosevelt. I’ve enjoyed and learned a great deal since starting as a fifth-grade lead teacher, then transitioning to teaching 7^th and 8^th-grade Ancient and Medieval History, and finally 10^th-grade Humane Letters. Choosing to step out of full-time classroom teaching was daunting at first; however, as I’ve continued to work alongside our wonderful high school students and families, I’ve found fulfillment in supporting young adults into the next stage of their lives. With our first senior class upon us, I’m eagerly awaiting all the first/last days, application deadlines, acceptance celebrations, decision day, and many other special events. The road to graduation will have joy, excitement, nerves, and tears, and I can’t wait to savor every moment.

I earned my Master of Social Work from Arizona State University in 2023. This is my second school year at Roosevelt and this year, I have the privilege of serving as the counselor for students in Kindergarten through 12th grade.

It is an honor to encourage, advocate for, and walk alongside students, helping them build confidence, resilience, and the skills they need to thrive both in school and beyond.

“Learning is one of life’s greatest adventures, and there are no limits to how much we can learn. Watching my students learn and grow reminds me of my own journey of continual development through curiosity, reading, music and a strong connection with nature.

Hello, my name is Joshua Guthrie! I have been teaching for two years, one of which was spent teaching in Fukui, Japan. For me, being a teacher means equipping people with tools to be curious, to understand life and all its subjects. Middle school me passionately hated literature because I didn’t know how to understand it; I couldn’t find something to enjoy during the reading process. So, my calling and goal as an educator is to enable students in this formative time to discover that they can find that something they enjoy about literature just as I did.

Mr. Kiser developed a love for natural sciences and mathematics and the arts at an early age. After initial studies in pre-med and biochemistry, his focus shifted to physics and chemistry, graduating from Caltech in engineering and applied sciences, with additional Ph.D. graduate studies in Materials Science and Solid State Physics. 

He went on to a 27-year career in Regional and Corporate Director roles in laboratory-related technical operations and regulatory compliance, providing analytical testing support and consulting services for a wide range of private entities, state, and federal agencies for prevention and/or resolution of public health-related incidents.

Post retirement, Mr. Kiser moved to Phoenix, AZ. Recognizing his desire to continue to engage intellectually with the mathematics and sciences, he began seeking education-related opportunities, and eventually discovered Great Hearts Academies.

Now entering his 11^th year at with Great Hearts and 4^th year at Roosevelt Prep, he has provided instruction in mathematics from Pre-Algebra through Calculus II, all of the high school sciences, and supported the development of both mathematics and science curriculum for Great Hearts. In addition to teaching both Calculus I and II, and Physics I and II this year, he also sponsors the Mathematics Club, assists with the school-wide annual participation in the American Mathematics competitions, and supports his colleagues as the Master Teacher and Instructional Coach for High School Mathematics and Sciences.

Ms. Michaels was born and raised in Sacramento, California. She studied the Liberal Arts at St. John’s College in Santa Fe, New Mexico, where she focused on philosophy, the history of mathematics and sciences, modern literature, and Ancient Greek tragedy.
She desires to spend her life learning how to ask good questions and have good conversations, and she is a firm believer in the power of seminar. She walked the Camino Frances and traveled mostly by car to each of the 50 United States because she thinks the best way to traverse broad distances, physically and intellectually, is slowly, adventurously, and close to the ground.
In addition to reading and thinking about the Great Books, Ms. Michaels loves to run, hike, camp, swim, dance, and spend time with her people. She also has a particular love of mischievous dogs.

“Live with your century, but do not be its creature. Serve your contemporaries but give them what they need, not what they praise.” (Friedrich Schiller, 1795). The human story is one of struggle, of taking two steps forward and one step back, of enlightenment and regression, all guided by ideals that give that struggle meaning and a life worth making. This story is the inheritance of every child. It is theirs to take up and continue with their time in the sun. My humble calling is to guide students as they take their first steps in this story and as they make its ideals the responsibility of their own lives. Studying Latin teaches our students how to read and to write, not just in Latin but in English or any language. Studying economics teaches our students how cooperating in a division of labor moves all of us from scarcity to abundance. And giving form to these studies, the Humane Letters inscribe civilization’s deepest ideals, and the stories showing them, in the hearts of our students. To prepare for this calling, I studied at the University of Chicago and the University of Leipzig.

My name is Kelsey Nichols and I hold a Bachelor of Science in Biology from Grand Canyon University. I am so excited to share my love of Biology and the ordered universe with students. Having always been the student who asked “why” over and over and wanted to understand the details of scientific concepts or cellular processes, I look forward to exploring those answers alongside the 9th graders this year. From photosynthesis and cellular respiration to human body systems, we will answer so many “why” and “how” questions and grow in our wonder at the complexity of living things.

My passion for teaching is rooted in a deep belief that education cultivated both the intellect and the character.  I began my undergraduate studies in chemistry at Howard University, where I developed a deep appreciation for logical reasoning, scientific inquiry, and the pursuit of truth.  Over the past 24 years, I have taught mathematics and science, as well as computer programming in private, public, and boarding schools, as well as internationally in Morocco.  These experiences have enriched my perspective and strengthened my commitment to serving student from diverse backgrounds.  I believe mathematics reveal the beauty of order and truth, and I am dedicated to cultivating wonder, virtue, and disciplined thinking in the classroom.
