what other past clients have said about Sistine & Randy:

Ed & Lois had lived in California for over 30 years, and upon retiring, were ready to move to Arizona. After deciding on Tucson, they found Sistine & Randy through the Internet before beginning the process of looking for a home. Inexperienced in real estate matters, they entrusted every detail to Sistine & Randy.

“Sistine & Randy were there to help us every step of the way with our relocation to Tucson. They even worked with the real estate agent in California to coordinate the closing of both properties so that we could move in without a delay, as our furniture was en route. As a matter of fact, when we were running around like chickens without our heads, they kept their COOL . . . Being out of state, we had to rely on them 100%, and as a result of their outstanding service, we refer them to as many people as we can.” ~ Fast Eddie & Lois, 2-9-2003

With the news of baby Chloe on the way, Karin, Sean, and brother Dalton needed to find a bigger home that would fit the needs of their growing family. Karin, a nurse at The University of Arizona and Sean, a major and combat search and rescue pilot in the Air Force, both work full-time. They realized the job of selling their home and buying a new one was something they did not have the time or the expertise to manage on their own. Sistine & Randy came highly recommended to them by two past clients.

“Through what we thought would likely be a difficult and lengthy process, Sistine & Randy provided endless guidance and patience with us so that the entire experience was actually quite simple and enjoyable. Rest-assured, we give all of our friends and family our strongest recommendation to see you when they enter the market to buy or sell a home.” ~ Karin & Sean Choquette, 9-25-2003


“Sistine & Randy know real estate laws and procedures very well, and they helped us at every turn in the process of selling our home. Plus, we got the closing date we wanted! Thank you for the “extra miles” you go for us!” ~ Else & Rudolf Samann, 1-13-2004







I’m very happy with my house and really like the neighborhood. You found me just the house I wanted and went above and beyond to insure everything got done before closing.” ~ Ross Curtis, 3-05-2002










“Sistine and Randy know property values. They are consummate diplomats and work hard to ensure that all parties are treated fairly and reach their goals.” ~ Ann Kerwin, PhD

“Hello Sistine & Randy, I would like to take a moment to say thank you for everything you did to keep this transaction together, I am so looking forward to working with you in the near future.” ~ Rodney Lewis, REALTOR®, 8-20-2010

“I really appreciate Sistine & Randy’s efforts in finding me a home. Their personal touch and attentiveness made for a gratifying home-buying experience.” ~ John Valdata

“It is very refreshing to have truly professional real estate agents looking out for my best interests. You were a pleasure to work with and you checked to see that every ‘i’ was dotted and every ‘t’ was crossed on the huge pile of paperwork that you managed for me.” ~ J. Hartman, 4-30-2004

“Purchasing our first home seemed like a very daunting task, but Sistine & Randy were with us every step of the way answering all of our questions. They were knowledgeable in every step of the process, and most importantly, they did everything with a smile and genuineness. We have found our permanent REALTORS® for as long as we reside in Tucson.” ~ Kevin & Natalie Collins
