Meet The Doctor

CHIROPRACTOR

Dr. Kaylan Lane

Born and raised in Los Angeles, from an early age Dr. Kaylan Lane always knew that she would pursue a career in healthcare. Growing up in a wonderful yet older family, she grew up seeing her loved ones handle chronic illnesses and physical pain, everything from high blood pressure, pneumonia, chronic back pain, to cancer.

From a young age she experienced her loved ones spend one too many nights in hospitals, be prescribed a multitude of medications, and endure too many surgeries. That was all the motivation Dr. Kaylan needed to pursue higher education in the medical field.

She saw how their doctors were just masking the problem instead of helping her loved ones overcome their issues. That was her determination to seek out ways to help outside of traditional medical care, identifying the benefits of structurally and neurologically based chiropractic care.

Dr. Kaylan graduated from San Francisco State University with a degree in Kinesiology with an emphasis in Exercises and Movement Sciences in 2016. After her undergraduate studies, Dr. Kaylan returned to Los Angeles where she pursued a career as a Master Personal Trainer.

She also worked as a Physical Therapy Aide where she worked in a multidisciplinary clinic and collaborated with Chiropractors, Physical Therapists and other practitioners with various therapeutic and functional therapeutic practices to help with athletic sports management, patient recovery, and preventative care.

Dr.Kaylan started her chiropractic career in 2019 and attended Southern California University of Health Sciences and obtained her Doctor of Chiropractic degree in 2022. During her time at SCUHS, she started studying the Gonstead Method. She has countless hours learning and practicing as a Gonstead Chiropractor, continuing to attend numerous seminars and conferences year-round. Being a chiropractor with Ahava Chiropractic since 2023, she looks forward to continuing to provide efficient and inclusive care to her community and patients.

Dr. Marcus Garcia

Dr. Marcus Garcia grew up in Riverside, California as the oldest of four siblings. From an early age, he developed a strong appreciation for movement and physical activity through playing soccer, learning firsthand how exercise contributes to overall health. Over time, however, Dr. Garcia came to understand that being truly healthy is far more complex than movement alone.

While he never experienced a major injury himself, Dr. Garcia witnessed the challenges many individuals face within the traditional healthcare system, particularly when communication and understanding fall short. These experiences shaped his desire to provide clear, compassionate, and patient-centered care that meets people where they are.

Dr. Garcia began his academic journey at California State University San Marcos, where he graduated in 2020 with a Bachelor of Science (BS) in Kinesiology with an emphasis in Physical Therapy. During his final year of undergraduate studies, he visited a provider who practiced the Gonstead Technique, an experience that sparked a deep respect for this approach and its ability to identify and address the root cause of health concerns rather than simply managing symptoms.

Inspired by this experience, Dr. Garcia went on to pursue his Doctor of Chiropractic degree at Life West College in Hayward, California, where he graduated in 2024 with Magna Cum Laude honors. During his training, he developed a strong foundation in structurally and neurologically based care, with a focused dedication to practicing the Gonstead Technique.

As part of the team at Ahava, Dr. Garcia is committed to serving the community as a whole by providing thorough, intentional, and individualized care. He strives to ensure every patient feels heard, understood, and empowered, while supporting the body’s natural ability to heal and function at its highest potential.

Dr. Nathan Sakai

Born and raised in Chino Hills, Dr. Nathan Sakai began his professional journey in a unique and creative field before entering healthcare. He earned his bachelor’s degree from California State University, Long Beach (CSULB) in Jazz Saxophone and spent ten years working as a full-time musician. Through years of performing, teaching, and collaborating with others, Dr. Sakai developed a deep sense of discipline, awareness, and connection — qualities that would later shape his approach to patient care.

As meaningful as his career in music was, Dr. Sakai felt called toward a profession that allowed him to help people more directly and make a tangible impact on their daily lives. That desire ultimately led him to chiropractic and back into higher education, where he could combine his passion for understanding the human body with his commitment to service and healing.

In 2021, Dr. Sakai began his chiropractic education at Southern California University of Health Sciences (SCUHS). During his time there, he pursued a comprehensive education that included training in sports medicine, developing a strong understanding of biomechanics, injury prevention, rehabilitation, and performance-based care. He obtained his Doctor of Chiropractic degree in 2025, equipped with a foundation that bridges clinical precision with functional movement and athletic care.
While at SCUHS, Dr. Sakai also began extensive study of the Gonstead Technique, a structurally and neurologically based chiropractic method known for its precision and specificity. He has dedicated countless hours to learning and refining this approach and continues to attend seminars and conferences to deepen his expertise as a Gonstead practitioner.

Today, Dr. Sakai approaches chiropractic care with intention, attentiveness, and respect for the body’s innate ability to heal. His goal is to provide thoughtful, individualized care that supports long-term function, resilience and overall well-being. He is committed to serving his patients with clarity, integrity, and care, and looks forward to continuing to support his community through efficient, patient-centered chiropractic care.

CHIROPRACTOR

Dr. Robert Rosas

Dr. Robert Rosas is the youngest of six children and was raised in a close-knit family rooted in love and strong support. Growing up, he witnessed several loved ones struggle with preventable illnesses such as diabetes, pneumonia, and heart disease—experiences that profoundly shaped his calling to serve others through healthcare.

A pivotal moment in Dr. Robert’s life came when he saw his own mother suffer from chronic pain. Although traditional medical approaches—including medications, injections, and surgery—offered temporary relief, they failed to provide lasting healing. Determined to find a better solution for his family and others facing similar challenges, Dr. Robert discovered structurally and neurologically based chiropractic care.
Inspired by its natural and restorative approach, he pursued a Bachelor of Science in Human Anatomy from Cleveland Chiropractic College. He later earned his Doctor of Chiropractic degree from Life Chiropractic College West in 2012, graduating as one of the youngest members of his class. Committed to clinical excellence, Dr. Robert has completed extensive postdoctoral training, including certification in the Webster Technique and more than 200 hours of advanced study in the Gonstead Technique.

Dr. Robert’s passion for service extends beyond the clinic. He has volunteered internationally in Guatemala and El Salvador and has served local communities through organizations such as San Francisco City Impact in the Tenderloin District.
Since beginning his practice in 2012, Dr. Robert has dedicated himself to helping individuals and families experience lasting health and wellness. After practicing in Northern California’s Bay Area for four years, he founded Ahava Chiropractic in Upland, California, in October 2019. In 2022, he relocated the practice to Rancho Cucamonga, where he continues to serve patients throughout San Bernardino, Riverside, and Los Angeles counties with compassionate, personalized chiropractic care.
Dr. Robert is committed to helping his community find hope, healing, and optimal health—naturally.
