Dr. Kristal began her nontraditional route to the medical field as an artist, who volunteered as a community sexual health educator. While advocating for HIV awareness and education, she decided that she wanted to attend medical school to help find a cure for the disease. (Things didn't go as planned.) In the midst of applying to allopathic medical school, Dr. Kristal began her own personal journey towards health and realized that she didn't know what health and wellness were. While researching, she came across a magazine article that described 7 different type of doctors and made the decision to attend naturopathic medical school. Naturopathic medical school deepened her appreciation for holistic approaches and reinforced her belief that you have to create the conditions for health.


Dr. Kristal loves helping her patients make better choices and learn healthy habits to improve their overall health and wellness. She understands the uniqueness of each individual and treats the whole person. 

She is an expert at sexual health education, naturopathic nutrition, and bridging the gap between conventional medicine and alternative therapies. She specializes in prevention, hormonal imbalances, gastrointestinal disorders, and autoimmune conditions. She is passionate about helping individuals prevent and manage disease, and wants to be the reliable source of health and wellness for people of color.
