What My Clients Say? Testimonials

Heather, Thank you for everything. You are a star!


Heather is amazing! Whether it was recommending places to stay or helping to get us into the best restaurants in town at the last minute she is incredible. She always has a smile on her face and is one of the major reasons we keep coming back to Aspen!

Heather is one of the greatest to work with. She's always so helpful and full of Aspen knowledge! She is also the kind of person that would do anything for her clients, like bring one of her clients coffee pods at 6am because he realized he ran out and would not be able to continue his day without!

Nic R.

Supervising Producer of The Real Housewives of Beverly Hills Thank you for saving the day! Aspen would NOT have happened without you.

I met you years back at Dancing Bear Aspen and I continue to entertain the possibility of an eventual home in Aspen.... I live in Louisville, CO and After the fires ( I'm having a new experience about what I love or don't love, what I remember...) without too deep a dive here, know I remember you and your hospitality and I loved that the Agency gave to our town recovery, so I'm hoping we can cross paths again. In the meantime, thank you.

Thank you so much for everything! It was such a fun experience with you and I really think it will be perfect for us right now! Again, thank you!

It was truly a pleasure working with you on this transaction. I know many people write that and I, too, have written it often but, from start to finish, you were so great to work with. You were so helpful and patient and always willing to get us the answers quickly whether you had them or had to get them from someone else. As you know, there are so many agencies these days and I have dealt with a few. Most often times than not, the transaction may start off smoothly but they end rather disappointingly. I’m not trying to criticize your competitors in this email so we’ll just focus on how great you are. 😊 I really am grateful for all that you did and I hope that my clients have future transactions in Aspen as you will be the only agent I will call! Thanks again for everything!

Jean L.
