Jennifer became a Nursing Assistant, Restorative NA, and reignited her fulfilling passion to serve and help others. There after, she worked in the Home Health industry, caring for people who were suffering from Multiple Sclerosis, Parkinson’s, Dementia, Epilepsy, Anxiety , Cancer and Hospice care.
That’s where Jennifer met Valentia Valentine (owner of Synchronicity Holistic). Valentia was using Cannabis and I saw it’s positive results in treating her debilitating symptoms of MS. MS has been close to me. I have two sisters who suffer from this disease. Valentia was Inspiring and enthusiastic, eager to share her knowledge and experience, trickling it down to any and all.
Seeing Cannabis in its application and being what she calls “Boots on the ground”, watching the patient’s quality of life begin to improve as well as seeing adverse effects from this beautiful plant made me want to have a better understanding on how Cannabis works in the body, and the science behind it. More importantly how to better serve her patients as a caregiver and advocate. Jennifer became certified in Cannabis and is humbled to its potential and knowing we have lots to continue to learn. I am excited for this wonderful opportunity Synchronicity Holistic has provided, and look forward to making a positive impact on our patient population, as well as supporting our Cannabis consumers as a whole.

KENDRA COLLINS

Sales Manager

Kendra Collins has been working on the Monterey Peninsula in a Management capacity for over two decades. She has come to Synchronicity with a corporate retail background where she was a public speaking educator for a large local grocery chain. However, her passion for the Cannabis industry started just five years ago when she walked into Higher Level in Castroville as a medical patient. She was blown away by the amount of knowledge and education the budtenders wanted to share. This inspired her to self educate and learn everything she could about this amazing plant. Kendra eventually started working as a receptionist for Higher Level before becoming a budtender, and finally she was promoted to Purchasing Manager. Kendra then went on to work for OZ distribution and there, she obtained the knowledge that pertained to the distribution side of the cannabis industry. Kendra, has since then, also been involved in the opening one of the newer dispensaries on the peninsula, The Reef. There, she was the inventory manager starting opening day; that was until she came to Synchronicity Holistic, the premiere Cannabis Wellness Center. Here, she is able to continue to share her knowledge and passion for cannabis education nearly every day.
