Sarah Martinez

An educator at heart and Loan Officer by trade, Sarah Partin Martinez emphasizes empowerment throughout the lending process and beyond. Leveraging skills honed throughout her diverse professional career, she provides homebuyers and investors from all walks of life with the informed support and guidance necessary to achieve their unique goals. Furthermore, she enjoys partnering with stakeholders to provide wraparound support and a seamless experience for everyone involved in the purchase process.

Always quick with a smile or friendly word, you can often find Sarah out-and-about meeting new people or enjoying the company of long-time friends and family. Because her husband is a California-born foodie, she is always on the hunt for new local(ish) food spots to try. With a multicultural family of music-lovers, Sarah often attends various cultural celebrations and live music/art performances with her husband and two young daughters. Ultimately, Sarah values fellowship and uplifting the people around her and it is her mission to promote socio-economic mobility by empowering folks to build generational wealth and financial wellbeing through real estate ownership.

Jan Collier

Jan Collier, the Loan Officer Assistant for Melissa, has been in the service industry for more than 40 years. Interacting with her, you will discover a warm, empathetic, and supportive listener, with a keen sense of attention to detail and follow through. She wants to understand you, your circumstances, and support you to meet your needs and goals.

Her background is in service to others. Initially after experiences in retail and office management, she dove deep into the lifelong professional role of a Registered Nurse – nurturing patients, families, co-workers, and students – to achieve the BEST outcomes possible. Her skill set includes health promotion, mentoring, coaching, problem solving, and leadership development to name a few. Modest about being a Veteran, she is grateful to have had the opportunity to serve her country.

Her academic accomplishments – Nursing (BSN, MSN), Business (MBA), and Military (CGS Diploma) – prepared her well for the role of Loan Officer Assistant, that she now enjoys in “retirement”.

Her passion to serve is in perfect alignment with Melissa, to empower others to become financially literate, and have a solid foundation of financial well-being. Empowering others may lead to a fulfilling lifestyle and good health. How wonderful to gain wealth through real estate, only to enjoy the fruits of your labor in building generational wealth too!
