HR & Finance Specialist (Temporary)

What to Expect Wonderist Agency is a full-service marketing agency that supports 1,200+ dentists around the country. We pride ourselves on ditching the old fashioned marketing model of stock photos and templated sites. We strive to tell our clients’ stories with bespoke brands, impactful photo and video shoots, and stunning website design (Here is a great example of our work: www.valordentaltx.com) We’re a team of over 90+ passionate marketers with our headquarters nestled in sunny San Diego. We are walking distance from local hangouts, bars, and the famed Liberty Station. While many companies simply check the required boxes when it comes to culture, a well-balanced team and positive office culture has been the core of our success from the start. We are a social team at heart, and that is one constant that hasn’t changed with all the movement this economy and industry has seen. We have embraced a hybrid work model where local team members come in at least two days a week. This allows us to work from home and have flexibility, without altogether forgoing the excitement and moments of collaboration and inspiration you can only get from in-person time. Not to mention, we also genuinely enjoy spending time together and socializing. We celebrate new ideas and prioritize a culture of trust and respect where team members can grow and take risks. Each quarter we host events under our four cultural pillars; health & wellness, personal & professional development, social good, and social.
