Our People

Meet your new marketing team:

Dallas Riffle - President

Dallas Riffle


I can confidently say that I was born to do this. Everything in my life has led me to the world of marketing, and I absolutely love what I do. I started DRM in 2013 in a tiny studio apartment in the Birdtown section of Lakewood, Ohio, and to see our clients flourish because of something we do is an incredible gift. Creating great marketing is a thrill; I get the same rush that some people do jumping out of planes or downhill skiing.

I attended the Meyers School of Art at the University of Akron with a focus in drawing and painting. Then I went on to study graphic design, illustration and web design at Tri-C.

In my free time, I enjoy music of all kinds. I’ve been a musician for several decades and still make time to make music whenever I can.

Colleen Masters - Director of Operations

Colleen Masters

Director of Operations

I have more than a decade of experience in the digital marketing industry, working in both corporate and agency environments, with expertise in ecommerce, healthcare and higher education. Throughout my career, I have evolved from a marketing specialist, to client services, to managing the full scope of business operations. My strengths include workforce planning, talent and resource management, and employee development.

My focus is on improving DRM’s bottom line through the integration of people, systems and processes. My goal is to support the people who support our clients.

I live in Avon, Ohio with my husband Scott and my two sons, Parker and Connor. During my time away from work, I enjoy being with my family, cooking, running, and yoga.

Dave Berman - Creative Director

Dave Berman

Creative Director

I have been a part of the Cleveland design community for over 15 years, with experience as varied as helping grow a start-up integrated marketing agency to being part one of the world’s largest interactive agencies.

I bring extensive experience in integrated marketing, website design and user experience (UX), digital marketing, and brand strategy, messaging, and identity creation, as well as a passion for forming human connections through smart creative—beautiful design and engaging content.

While I’m not pushing pixels around, I’m enjoying all the west side has to offer and spending quality time with my 4- and 6-year-old boys. I’m infatuated with The Muppets, and, I vow that one day I will start running again.

Efi Golan - Director of Web & Marketing Technology

Efi Golan

Director of Web & Marketing Technology

I'm a software developer with a real passion for problem-solving. I love nothing more than taking a complex challenge, breaking it down into manageable parts, and then developing innovative solutions that make a difference to businesses. This is true across the entire lifecycle, from web, application and API development to my other passion: incorporating technology and strategy into stand out digital marketing.

Beyond software development, my bread and butter, I’m particularly proud of my experience teaching and mentoring others. I think it's really important to pay it forward and help others grow into confident, capable professionals.

When not in front of a screen, I spend time with my wife, Michelle and my two daughters, Shai and Izzy, visiting northeast Ohio trails with our dog, attending music concerts, and finding creative recipes incorporating vegetables and herbs from our garden.

Kasey Crabtree - Director of Business Development

Kasey Crabtree

Director of Business Development

I am a professional communicator and earned my BS in Communication from Northwestern University and spent many years in radio as an on-air personality, including 15 incredible years at WNCX in Cleveland.

What excites me about DRM is that my career is closely aligned with its mission. I have always been great at making genuine connections with people, and DRM uses creativity to connect our clients’ brands to its audiences. It’s like a Wonder Twins superpower! Together we are going to create connections and help businesses grow and it’s going to be a thrilling journey!

I’m a huge music fan and live with my cat siblings Shelby and Arabella and love cowboy boots – both wearing them and searching for unique vintage styles.

Megan Ondich - Account Manager

Megan Ondich

Account Manager

In my role as Account Manager, I help DRM serve our clients in account, project and sales support. My passion for creativity and art is what lead to me to marketing. I love tackling new projects and helping clients grow in a measurable way! I earned a Bachelor of Business Administration degree from Kent State University, where I majored in Managerial Marketing.

When I'm not helping DRM clients, I enjoy attending concerts, visiting local breweries, and exploring the Cleveland Metroparks while running, biking, or kayaking.

Cassidy Straub - Graphic Designer

Cassidy Straub

Graphic Designer

I earned a visual communications degree at Cuyahoga Community College and bring a fresh perspective and exuberance to DRM. I love staying on top of trends and how people engage with digital media and design in general, and that drives me to be curious and look for new ways to do things and new ways to design.

What I love about what I do is that I don't feel a ceiling, I’m not racing to an end, I’m not motivated to get to an imaginary finish line; design is always changing and that allows me to just keep going and going. Plus, I like a little bit of doubt and pressure, and graphic design provides that every single day!

In my free time, I enjoy gardening, sewing, and all things creative in the physical world (when I’m not plugged in, of course).
