creative, exceptionally thorough – very straightforward and easy to work with

We received an email from a client who looked at our site and noticed several problems and wording we did not write. I called Stefanie in a huge panic after I looked at the site myself. In just a few minutes she knew something was wrong. She said she would get right on it with her top security person. About 24 hrs later I received a detailed email outlining the things Stefanie & her team did to our site – it was very impressive! She had not only cleaned it up but also installed protective measures to prevent further infections/problems. My next step is to meet with Stefanie to have her look at revamping our site to not only provide additional protection but to liven it up. I’ve seen her other work & I want that same experience for our site! I’ve dealt with other web people over the years and NOBODY is quite like her in terms of the passion she brings to her work – it really shows through. She is very creative in her design, exceptionally thorough in her work and very straightforward and easy to work with. On top of that, she is as nice a person as there is.

Stefanie is a rare GEM!

5 StarsStefanie is a rare gem!  I was nervous about using someone that had so few reviews, but this turned out to be the BEST decision I could have made for my company.  She walked me through every step of building a website so that I can know how to create more and manage it on my own.  Who does that?  She not only has the skills and experience as a top notch web  & graphic designer, but has the heART of a teacher and mentor!  She is absolutely committed to her client’s success!

My customer service experience with Stefanie stood out above all others of her excellent qualities.  I always felt like I was her priority and was very valued.  I never felt like I was a job or project to her, but that she was serving me a person.  She is extremely patient, kind and her response time was always timely.

When doing business, character is important to me.  Stefanie exemplifies great integrity.  She will make sure you’re doing things the right way without cutting corners.  She is conscientious and trustworthy.  Because of this, I feel comfortable referring her to people that I know.  And most certainly comfortable hiring her for future projects!

A creative genius with stellar technical abilities

5 StarsStefanie has been such a key player in my business and the businesses of my clients.  I hired Stefanie to design my logo, create my cover photo, create my stationary, create my business cards, and build my website.  Through each of these projects, Stefanie delighted me with her creativity and VERY QUICK turnaround.  She is a creative genius with stellar technical abilities.  Since she completed my business branding projects, I have happily referred her to several of my clients.  She consistently delivered top-tier custom web design, branding, and logo creation. I highly recommend her!

5 StarsStefanie Herzer of heART Web Design is A+wesome!  She helped me create an entirely new website for my business, and she delivered results!  Not only do we love the look and feel of our new site, but IT BRINGS IN BUSINESS!   Our phone rings because it’s attracting traffic, thanks to Stefanie.  Not only is she a great web designer, but she’s also an incredible photographer, so she can provide more services under the same package.  Stefanie is the type of person where if something’s not just right, the way that’s best for her clients, she won’t rest until it’s fixed.  She has an incredible background in IT, and offers a fantastic, well rounded solution to her clients.  I can’t thank heART Web Design and Stefanie enough for all she’s done for our company!

Wow! You *are* fast!

Thanks again. This is really, really great.

So lovely to not have that clenching feeling in my stomach when I look at the website. 🙂 Ahhhhhh.

What we didn’t expect

When you hire a web design company you expect a professional that knows how to put a web site together. What we did NOT expect was the amazing photography that Stefanie of heART Web Design provided as part of her service. We now have photos of all our staff members on our site and although we are a small mom and pop shop, our website looks like a million bucks. We couldn’t be happier!

Stefanie really cares…

I have been working with a dozen web designers. Never before did I feel that they really cared about my needs. Since I started working with Stefanie and her team (note: the people I recommended for social media posts), my website does not only look great, but it also gets found. It is so refreshing to work with somebody who cares so much.
