​Licensed Professional Counselor Certified EVOX Practitioner

Rennetta Nikolic


Ashley D. Swanson, MS, LPC received her Master’s degree in Counseling Psychology from the University of Kansas (Rock Chalk!). She is a Licensed Professional Counselor in the state of Kansas and is currently working towards obtaining her LPC licensure here in the beautiful state of Colorado. Ashley completed her clinical practicum at a community mental health facility in Leavenworth, Kansas. During her time at the Guidance Center in Leavenworth, Ashley gained invaluable experience working with adolescents, adults, and families. She specialized in counseling for anxiety, depression, and grief, as well as more deeply ingrained patterns of maladaptive behaviors such as personality disorders.

Ashley takes an integrative approach to the therapeutic process, as she believes that therapy should be a direct reflection of the complex and multifaceted nature of the human mind. She is trained in various therapeutic modalities including Cognitive Behavioral Therapy (CBT), Person Centered Therapy, and Mindfulness Based Cognitive Therapy (MBCT). Ashley believes that therapy should never be approached from a “one size fits all” perspective. Because of this, she strives to make the therapeutic experience one that is built on mutual respect, trust, and healthy communication between client and clinician.

Acacia Whole Health

Rennetta Nikolic began exploring alternative medicine in 1994, when her first child was diagnosed with milk and wheat allergies. With the help of a supportive pediatrician, she began using homeopathy, herbal remedies and diet alternatives to keep her family healthy. As her knowledge grew, neighbors, friends and family increasingly requested information on natural remedies for their own use. 

In 1996, Rennetta began professionally using alternative remedies and modalities with animals, and her knowledge continued to expand. In 2001, she began her formal education in alternative health, and began working as an intern at Acacia Whole Health. Rennetta Nikolic is now the owner and primary Traditional Naturopath at Acacia Whole Health. She was certified to use Electro-Dermal Screening devices through Computronics Corporation, in 2001, and through the American Association of Acupuncture and Bio-Energetic Medicine, in 2010. 

Moving to Hawaii in 2007 allowed her to continue to learn natural healing practices of different cultures. She also completed her Doctorate of Naturopathy during this time. Rennetta understands the healing power within each of us. She works with the individual needs of each person, building the best health program for you. 

“Given proper nutrition, and natural help when needed, the body has the ability to heal beyond current conventional expectations. I look forward to seeing you return to optimum health and teaching you to maintain your highest vitality!”
